Keywords: medicinal plants; phytochemicals; toxicity; treatment; antimicrobial; resistance
This study was conducted to assess the proximate, mineral content, and phyto-constituents of several therapeutic plants and herbs found in India. The medicinal properties of herbs are attributable to the existence of several complex chemical substances known as secondary metabolites, which are exclusively accumulated in diverse sections of the plant such as leaves, stems, roots, and flowers. These secondary metabolites or phytochemicals contain saponins, alkaloids, flavonoids, triterpenoids, diterpenoids, tannins, and steroids, which are considered a valuable source of nutrition and also possess pharmacological properties such as antimicrobial, anfungal, antiviral, antihelminthic, antioxidant, hepato-protective, antibacterial, immunostimulatory, hypolipidemic, anti-rheumatic, antidiarrheal, anti-pyretic, antimalarial, anticancer, and anti-allergic properties, among others. Medicinal plant extracts have traditionally been used to treat diseases and inhibit the activities of pathogenic organisms such as Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus, Bacillus subtilis, Penicillium notatum, and Candida albicans. It was determined that all medicinal plants investigated had varied chemical compositions, which might be ascribed to the plant's age, specie, extraction procedure or processing, storage, geographical location, and other factors. This study will also provide information on emerging phyto-constituents, which can help to lower the growing incidence of antimicrobial resistance and bridge the gap between animal production and food safety.
Medicinal or herbal plants have nutritional, pharmacological, or therapeutic characteristics because they contain phytochemicals (Singh et al., 2002). They've been used to treat a variety of ailments for thousands of years. The use of terrestrial plants as medicines has been reported in Egypt, China, India and Greece from ancient times, and an astounding number of modern pharmaceuticals have been produced from them (Singh et al., 2002). Plants' natural ingredients or phytochemicals can be obtained from their stem barks, leaves, flowers, roots, fruits, and seeds (Wojcikowski et al., 2004; Singh et al., 2021).In 1999, the World Health Organization (WHO) reported that 80% of the world's population used medicinal plants to heal ailments. In recent years, medicinal plants have become a primary health supply for the pharmaceutical business (Phillipson, 1991).
Medicinal plants are currently gaining acceptance among literates in urban settlements, most likely due to the increasing inefficacy of many modern drugs used to control many infections, as well as the increase in resistance by several bacteria to various antibiotics and the rising cost of prescription drugs for personal health maintenance (Smolinski et al., 2003; Tzortzakis and Economakis, 2007). Current issues with antibiotic use, as well as the rising incidence of multiple-drug resistance strains of a variety of harmful bacteria, have reignited interest in plants having antimicrobial capabilities (Voravuthikunchai and Kitpipit, 2003).Antimicrobial resistance endangers the population by making infections difficult to cure and raising morbidity and mortality rates. It also raises the expense of disease treatment and management (Zhang et al., 2013; Winkel, 2015).
Secondary metabolites are the active ingredients in many plant-derived medications. Plant extracts' antibacterial properties may be attributed to a range of components, including aldehydes and phenolic chemicals (Yadav et al., 2010; Valgas et al., 2007). According to the World Health Organization (2001), there are over 100,000 medicinal plant species worldwide, many of which have yet to be identified. They perform multiple biological activities such as: antimicrobial (Daniel and Alagbe, 2023; Musa et al., 2021), antioxidant, anti-inflammatory (Demain and Fang, 2000), anti-helminthic, anticancer, antimalarial, anti-rheumatic (Daglia, 2012; WHO, 2000), anti-diuretic, anticonvulsant, antidiarrheal, antiviral (Ayanwuyi et al., 2010), hepato-protective, immuno-stimulatory, anti-fungal, dermato-protective, hypolipidemic
Infusions of any or extracts from plant parts have also been used traditionally for the treatment of various diseases and infections such as cough, chest, pain, waist pain, irregular menstruation, internal pile, malarial, quick ejaculation, headache, hypertension, dysentery, premature aging, memory improvement, blood cleansing, chronic venous, insufficiency, mental function, minor burns, scars, scieroderma, skin ulcers, varicose veins, wound healing, rheumatism, blood disease, congestive heart failure, urinary tract infections, venereal disease, hepatitis and high blood pressure phlebitis, leg cramps, gastro intestinal diseases, amongst others (Trentin et al., 2011; Singh et al., 2008). They have also been shown to suppress the activity of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus, Bacillus subtilis, Penicillium notatum, and Candida albicans, among others (Trentin et al., 2011; Yasunaka et al., 2005). However, factors such as species, age of medicinal plants, and geographical location may impact plant nutritional and phytochemical composition (Alagbe et al., 2021). Given the pharmacological or therapeutic activity associated with various phytochemicals in medicinal plants, it is necessary to identify their chemical components or phyto-constituents, as this could lead to the discovery of novel drugs while also providing information on their harmful effects.
Experimental Location
The experiment was carried out at Sumitra Research Laboratory Gujarat, India located between 23o 13' N and 72o 41' E. All laboratory kit/machines were operated according to their manufacturer’s recommendation.

Proximate composition of some sixteen medicinal plants found in India (expressed in %) is presented in Table 1. The crude protein values obtained in this study varied from 7.31 – 17.1 %, moisture (8.13 – 11.7 %), crude fat (1.29 – 2.61 %), crude fibre (10.9 – 18.4 %), ash (7.55 – 9.87 %) and carbohydrates (40.9 – 55.6 %). Centella asiatica had the highest crude protein value while Tribulus terrestris had the lowest value. Higher moisture content was recorded for Tinospora cordifolia while Symplocos racemose had the lowest value. Result on crude fibe, crude fat, ash and carbohydrate revealed that Tribulus terrestris, Glycyrrhiza glabra, Bauhinia variegate and Centella asiatica had a higher value compared to Crateva nurvala, Tribulus terrestris, Symplocos racemose and Psoralea corylifolia which had a lower value respectively.
As presented in Table 2, mineral composition of some medicinal plants found in India (expressed in mg/100g). Result revealed that calcium level varied from 155.7 – 211.6 mg/100g, phosphorus (78.9 – 114.2 mg/100g), potassium (398.7 – 831.1 mg/100g), magnesium (47.2 – 96.0 mg/100g), manganese (10.5 – 31.9 mg/100g), zinc (29.1 – 48.0 mg/100g), iron (5.12 – 13.2 mg/100g), selenium (0.43 – 3.11 mg/100g), copper (1.83 – 8.67 mg/100g) and sodium (101 – 132 mg/100g).
As presented in Table 3, phytochemical evaluation of some medicinal plants found in India (expressed in mg/g). Result showed that the concentrations of alkaloids, saponins, flavonoids, tannins, glycosides, steroids and phenols were greater in Terminalia bellerica (40.6 mg/g), Centella asiatica (45.8 mg/g), Bauhinia variegate (70.5 mg/g), Eclipta alba (29.5 mg/g), Andrographis paniculata (7.12 mg/g), Bauhinia variegate (6.17 mg/g) and Terminalia bellerica (92.5 mg/g) compared to those of Psoralea corylifolia (21.3 mg/g), Symplocos racemose (22.0 mg/g), Withania somnifera (37.0 mg/g), Plumbago zeylanica (16.3 mg/g), Tinospora cordifolia (2.06 mg/g), Psoralea corylifolia (2.67 mg/g) and Barleria prionites (51.4 mg/g) respectively.

According to Alagbe (2019a, 2019b), a plant's chemical makeup can be influenced by factors such as age, geographical location, and species. The crude protein range (7.31 - 17.1%) in this study was consistent with Huskie et al.'s (2010) established values for leafy vegetables (8.00 - 30.0%). The findings imply that these therapeutic plants provide both nutritional and pharmacological benefits, making them suitable for inclusion in animal diets. Andrew et al. (2023) reported protein concentrations for Dysphania ambrosoides (15.99%) and Crassocephalum crepidiodes leaves (17.11%) that are consistent with the investigation. Alagbe et al. (2024) found a lower value of 7.60% for Pterocarpus erinaceus leaves, 5.11% for Pterocarpus erinaceus stem bark, and 4.33% for the root. Mohammad et al. (2020) recorded a higher crude protein of 28.20 % for Vernonia amygdalina leaves. Protein are needed for the growth and maintenance of animals, they also play an integral part in the immune system and enzyme production in the body (Ojediran et al., 2024). The range of moisture content 8.13 – 11.7 % was within the standard range of 6 – 15 % reported for vegetables (Rishi et al., 2012). Therefore, high moisture content in the samples are advantageous because inhibits the growth of microbes on a sample (Adewale et al., 2022). The difference in moisture content between different plants is directly dependent on climatic changes (Goss, 1980). This result corresponds to the reported values by Adewale et al. (2022) for Pterocarpus carpus leaves (11.46 %) and stem bark (13.18 %) and lower when compare with the report of Alagbe et al. (2022) for Piliostigma thonningii leaves (7.23 %). The results on the crude fibre suggests that Tribulus terrestris had the highest concentration (18.4 %). Availability of such high contents in the diets of livestock’s helps to prevent gastrointestinal disorders and coronary heart disease (Ibironke, 2003). The crude fibre range (10.4 – 18.9 %) were within the range reported by Abiodun et al. (2017) for Chenopodium ambrosoides leaves (13.40 %) and Morinda lucida leaves (15.06 %) but lower than values recorded for Parquetin nigrescen leaves (22.05 %), Oscium gratissimum (22.02 %) and Magnifera indica (19.01 %) by the same author. Ash content of medicinal plants can be used to evaluate its mineral content (Daniel et al., 2023; Alagbe, 2022). The ash content range reported in this study 7.55 – 9.87 % showed that Bauhinia variegate had the highest mineral content suggesting that it can promote construction of muscles, blood cells, internal organs and enzymes in animals (Singh et al., 2022). Therefore, animals with a deficiency of minerals will never develop properly and are more susceptible to diseases (Alagbe, 2024). The mineral content of medicinal plants is in consonance with the reports of Amabye (2015) for Rhamnus prinoides leaves (9.50 %) and lower when compared with the reports of Raimi et al. (2014) for Sida acuta leaves (6.33 %). Crude fat content range of 1.29 – 2.61 % recorded for the medicinal plants indicated that Terminalia arjuna had the lowest value. This result suggests that they are able to maintain good health by preventing the incidence of cardiovascular diseases as a result of excessive fat consumption (Sodamade, 2013). Carbohydrate values (40.9 – 55.6 %) corresponds with the values of Abiodun et al. (2017) on Oscium gratissimum (50.06 %) and lower when compared with the report of the same author for Parquetin nigrescen leaves (36.03 %), Chenopodium ambrosiodes (4.36 %) and Magnifera indica (43.76 %). Availability of high carbohydrate content in a sample is helpful in providing energy and excess of it can be stored as fat which is stored in the adipose tissues of animals (Alagbe et al., 2023).
Calcium, phosphorus, potassium, magnesium, manganese, zinc, iron, selenium, copper and manganese in Eclipta alba (211.6 mg/100g), Barleria prionites (114.2 mg/100g), Plumbago zeylanica (831.1 mg/100g), Glycyrrhiza glabra (96.0 mg/100g), Terminalia bellerica (31.2 mg/100g), Terminalia bellerica (3.11 mg/100g), Bauhinia variegate (8.67 mg/100g) and Terminalia bellerica (132.0 mg/100g) compared to those of Crateva nurvala (155.7 mg/100g), Crateva nurvala (70.2 mg/100g), Crateva nurvala (398.7 mg/100g), Crateva nurvala (47.2 mg/100g), Andrographis paniculata (10.5 mg/100g), Psoralea corylifolia (27.6 mg/100g), Tribulus terrestris (5.12 mg/100g), Andrographis paniculata (0.43 mg/100g), Symplocos racemose (1.83 mg/100g) and Symplocos racemose (101 mg/100g) which had lower values. The variation in their compositions may be due to differences in geographical location and species of plants (Alagbe, 2021a). The result obtained showed that the medicinal plants contains appreciable quantities of minerals which are needed for the activation of enzymatic reaction in the body of animals (Ojediran et al., 2024; Alagbe, 2021b). Deficiency of minerals are known to affect the performance and health in both humans and animals (Thomas and Krishnakumari, 2015). Calcium and phosphorus are essential components of the skeleton and are necessary for the synthesis of structural proteins (Alagbe, 2021a). The calcium and phosphorus levels are within the standard range reported by Obazelu et al. (2021) for Combretum platypterum leaves (266.4 mg/100g) but lower than values reported for Ficus capensis leaves 186.0 mg/100g and 160 mg/100 respectively by Ngozi et al. (2017).Magnesium activates enzyme systems that maintain electrical potential in nerves, whereas potassium influences osmotic pressure and contributes to normal acid-base balance (Thomas and Krishnakumari, 2015). Iron is essential in mammalian diet to prevent anemia, and it is a component of hemoglobin and myoglobulin molecules that transport oxygen to and within cells. Zinc creates metalloproteinase and enzyme complexes that cannot be separated without losing activity (Alagbe et al., 2021; Adewale et al., 2021). They also help cells replicate and differentiate (Robert et al., 2003).
Phytochemicals are basically divided into two groups that are primary and secondary metabolites. Primary metabolites comprise common sugar, amino acids, proteins and chlorophyll while secondary metabolites consist of alkaloids, flavonoids, tannins etc., (Kumar et al., 2009). Phytochemicals like flavonoids and phenols are powerful antioxidants and have an important role in the health care system (Ojediran et al., 2024). The values of alkaloids, saponins, flavonoids, tannins, glycosides, steroids and tannins which varied from 20.6 – 40.6 mg/g, 22.0 – 42.0 mg/g, 37.0 – 70.5 mg/g, 16.3 – 29.5 mg/g, 2.06 – 7.12 mg/g, 2.56 – 6.60 mg/g and 50.9 – 92.5 mg/g respectively. Alkaloid, saponin, tannin and flavonoid concentrations were within the range reported by Aliyu et al. (2008) for the leaves of Anchomanes difformis (23.6 mg/g), Anisopus mannii (41.6 mg/g), Pavetta crassipes (39.6 mg/g), Stachytarpheta augustifolia (40.8 mg/g) and Vernonia blumeoides (38.2 mg/g) but lower than values recorded by Obazelu et al. (2021) for Combretum platypterum (3.52 mg/g). The role of medicinal plants in disease prevention or control has been attributed to antioxidant properties of their active constituents (Ivanova et al., 2005). Medicinal plants have been shown to function as free radical scavengers through anti-oxidative mechanisms mediated by polyphenols, flavonoids, ascorbic acid, and terpenoids, which have the ability to protect cell organelles from damage caused by free radical-induced oxidative stress by inhibiting the initiation or propagation of oxidative chain reactions (Ghaffar and El-Elaimy, 2012; Shittu and Alagbe, 2020). Alkaloids have been shown to act as painkillers as well as having antimalarial and antibacterial activities (Alagbe et al., 2024; Alagbe et al., 2020).Melaleuca Alternifolia (Cox et al., 2000), Cassia Occidentalis (Chukwujekwu et al., 2006), Rhamnus Californica, and Umbellularia Californica leaves have all been found to contain alkaloids and saponins (Carranza et al., 2015). Tannins are employed as antiseptics due to the presence of phenolic groups, and they have also been linked to antibacterial and antioxidant characteristics (Alagbe and Ushie, 2021). Saponins are also useful therapeutically because they have been proven to have hypolipidemic and anticancer properties (Carranza et al., 2015). Glycosides have a bitter taste and have been employed as flavoring ingredients in numerous pharmacological products (Sarker and Nahar, 2007).These natural metabolites are significant as prospective antibacterial crude drugs and a source of natural chemicals as new anti-infection agents (Dwivedi et al., 2011).
Medicinal plants are thought to be safe and free of adverse effects when used to improve animal performance. Herbs can be used as feed additives because they are suitable and preferred, have a minimal risk of toxicity, pose few health risks, are environmentally friendly, and are less expensive to produce. Differences in processing processes, species, geographical regions, plant age, and storage, among other factors, can all have an impact on the chemical composition of medicinal plants. Phytochemicals are natural substances that are easily digested by animals. They can also assist to slow the rise in antimicrobial resistance and improve food safety. They can boost feed intake and digestibility in animals while causing no negative effects or withdrawal periods, enhancing farmer profits.

I am very pleased to serve as EBM of the journal, I hope many years of my experience in stem cells can help the journal from one way or another. As we know, stem cells hold great potential for regenerative medicine, which are mostly used to promote the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. I think Stem Cell Research and Therapeutics International is a great platform to publish and share the understanding towards the biology and translational or clinical application of stem cells.
