“…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.

Synthetic chemicals have been used to control plant pathogenic nematodes in the farmers fields. These chemicals, though valued for their effectiveness, are costly and may constitute health hazards to farm households and the environment. Reducing these situations in the farms through use of natural plant extracts is one of the challenges in Nigeria. Powdery extracts of Jatropha curcas, Parkia biglobosas, Newbouldia laevis, Ficus exasperata and Cassia alata were evaluated for the control of M. incognita in yam bean (Sphenostylis stenocarpa Hochst ex A. Rich) at the University of Nigeria, Nsukka in Nigeria. Newbouldia laevis extract significantly (P<0.05) controlled the galling of Meloidogyne incognita, while the efficacy of other extracts were insignificant (P >0.05). Newbouldia laevis extract had significant effects on the height of the plant. Significant difference was observed on the plants height. Newbouldia laevis extract reduced the number of galls from 1.89 to 1.18 and increased the height from 106.1 to 213.3 cm and the number of leaves from 59.2 to 69.2 compared with control (water treatment). Cassia alata extract had a significant effect on both leaf numbers and stem height of the plant. It increased the number of the leaves from 59.2 to 81.3 and the height from 196.1 to 201.3 cm, and the number of root gall from 1.89 to 2.49.
