“…The alcoholic fractions of J. cinerea presented flavonoids, phenols, coumarins, and tannins; while the alcoholic fractions of J. cordata only presented flavonoids, phenols, and tannins. There are reports of other Jatropha species showing a high content of phenolic compounds [17,18]. On the other hand, coumarins in ethyl acetate and alcoholic fractions of J. cinerea were found.…”

Jatropha species have been shown to be an important source of secondary metabolites with different biological effects. Jatropha cinerea (Ortega) Müll. Arg and Jatropha cordata (Ortega) Müll. Arg are distributed in the Northwestern region of Mexico, are adapted to extreme weather conditions and are widely used (stems, leaves, and sap) in traditional medicine. The aim of the present study was to carry out the phytochemical characterization and the evaluation of the antioxidant activity in methanolic extracts of stems and leaves from J. cinerea and J. cordata. The compounds present in the extracts of both species were characterized by ESI-IT-MS/MS and quantified by HPLC-DAD. The results showed that the stem extracts of both species are rich in phenolic acids, while the leaf extracts are rich in flavonoids. Some of the main compounds found were gallic acid, gentisic acid, 3,4-Dihydroxybenzoic acid, vitexin, isovitexin, and catechol. Both species showed high concentrations of phenols and total flavonoids and antioxidant activity. J. cordata showed the highest antioxidant capacity and the highest concentration of phenolic compounds. Overall, both Jatropha species are a natural source of antioxidant compounds with potential biotechnological uses.

Jatropha chevalieri beille's foliage possesses haemostatic and vulnerary properties, capable of stopping bleeding by being applied directly onto wounds. Recently, the identification of novel antimicrobial phytoconstituents has become increasingly imperative. The pursuit of new sources of natural antioxidants, antimicrobials, and antifungal agents is of utmost importance. In this study, we explore the antioxidant, antimicrobial, and antifungal activity of methanol fractions derived from Jatropha chevalieri beille. We conducted a test for antimicrobial activity on a range of clinical isolates. We tested Gram-positive strains such as Listeria monocytogenes ATCC9144, Staphylococcus aureus and Salmonella typhimurium ATCC14028, as well as Gram-negative strains including Escherichia coli ATCC25922 and Pseudomonas aeruginosa. Additionally, we tested for antifungal activity against Fusarium oxysporum and assessed antioxidant activity using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. A significant discovery was made in the methanol extract of Jatropha chevalieri beille as it contained various secondary metabolites including flavonoids, polyphenols, saponins, and tannins. Furthermore, this extract demonstrated strong potential in terms of antioxidant, antimicrobial, and antifungal properties.Our results indicate that the methanol fraction derived from Jatropha chevalieri Beille is highly effective in combatting Escherichia coli ATCC25922, Salmonella typhimurium ATCC14028, and Staphylococcus aureus, and shows potential as an excellent agent for combating fusarium fungi. Moreover, this fraction displayed the greatest antioxidant activity, likely resulting from the presence of secondary metabolites. Additional research should be conducted to better identify and characterize these compounds and their biological activity.

“…In a study by [47] the phytochemical screening of Jatropha curcas leaf revealed the presence of tannins, saponins, flavonoids, alkaloids, oxalates and cardiac glycosides while [48] reported that root and latex extracts of J.curcas plant contained phenolics, flavonoid and saponins. Other phytochemical screening reported by [49] indicated the presence of nine different phytochemicals form Jatropha curcas in varying degrees.…”

Bixa orellana, Jatropha curcas and Cassia alata are three of the prominent plants used for traditional medicine in Nigeria. Dermatophytosis also known as tinea or ringworm is the most frequent superficial fungal infections in Nigeria. Objective: In this Present Study, We Aimed at Comparing The Phytochemical Components and the Antifungal Efficacy of these Medicinal against Selected Dermatophytes. Study Design: Cross Sectional Study among a Particular Population. Place and Duration of Study: Department of Microbiology, Federal University of Technology, Akure, Ondo State. Between March 2019 and September 2019. Methods: The phytochemical contents of the plants were determined and the in-vitro antifungal activities of Bixa orellana, Jatropha curcas and Cassia alata were screened against seven species of Trichophyton (T. ajelloi, T. mentagrophytes, T. rubrum, M.gypseum T. soudenensis, T. tonsurans and T. verrucosum) using agar dilution method. Results: The phytochemical screening revealed the presence of flavonoid, saponin, phenol, steroids, glycoside, phytosteroids, alkaloids, terpenoid, tannin, and cardiac glycoside in various quantities. The findings from our study showed that the ethanol extracts of these medicinal plants have more antifungal activities than other solvents. However, the hexane and ethanol extracts of Jatropha curcas was observed to be significantly higher than other extracts. The zone of inhibition recorded ranges from 22 mm-32 mm and the minimum inhibitory concentration (MIC) of 12.5 mg/ml was recorded. Conclusion: The ethanolic extract of Jatropha curcas showed broad effectiveness against the tested pathogens when compared to other plants and we conclude that the plants antifungal property is concentration dependent. However, we recommend further studies on these plants extracts using a large number of different isolates and solvents.
