Background: Oreopanax ecuadorensis Seem. is a plant from Ecuador, that is found in the Andean region of the country. The plant is commonly used in protective rituals, and as an antiflu, analgesic and disinfectant medicine. Aim: The research aims to extract and analyze the chemical composition and evaluation of its antifungal potential of the essential oil extracted from its leaves. Methods: steam distillation was used for the extraction of essential oil, the evaluation of its components was performed by GC/MS, and the antifungal evaluation by the disc diffusion method. Results: The essential oil was obtained with a yield of 0.05\%. 33 compounds were detected of which 30 were identified, corresponding to 99.28\%; the most abundant molecules were: thujene \<α-\> (36.63\%), followed by bicyclogermacrene with (8.76\%), pinene \<β-\> with (8.32\%) and limonene with 5.15\%. Three of the four strains evaluated were affected by the oil at concentrations of 1.25\%, inhibiting its growth. The strains were: Trichophyton mentagrophytes, Trichophyton rubrum and Microsporum canis. Conclusion: The essential oil shows good antifungal activity, which could be less than 1.25\%. In this way, this medicinal plant is valued by verifying ancestral knowledge in the use of medicinal plants by the Andean people of Ecuador.

Background: Oxalis pes-caprae is also called as \“sourgrass\” or soursob. The roots, stems and leaves of Oxalis pes-caprae have high medicinal values and have the function of antiinflammatory and analgesia, clearing heat, removing toxicity. In present study Oxalis pescaprae belonging to family oxalidaceae evaluated for pharmacological activities like cytotoxicity, phtotoxicity, antibacterial and antifungal bioassays. Materials and Methods: Cytotoxic activity was performed by brine shrimp bioassay using methodology of Atta- ur- Rahman et al., 2001. The phytotoxic activity was investigated by applying Lamna minor (as test species) following Atta-ur-Rahman et al., 2001. Anti-bacterial screening was conducted following Rathan (2000). Anti-fungal screening was carried out using agar well diffusion method following Perez et al. (1990) and Atta-ur-Rahman et al. (1991). Results: Its ethanolic extract showed highly significant (100\%) cytotoxicity with LD50 8.98 at 1000 ppm. Lemna minor phytotoxicity assay showed that O. pes-caprae chloroform extract showed 90\% inhibition at 1000 ppm with FI50 0.1048. Antibacterial bioassays showed that all the samples of the plant were significant against Xanthomonas, Clavibacter machengnitis and Bacillus at 1000, 1500 and 2500 ppm doses. Dose dependent antifungal activities against test species (Aspergillus flavus, Penicillium and Fusarium solani) were noticed for all the extracts at 100 and 1000 ppm. Conclusion: Pharmacological potentials showed that this plant can be used in upcoming time for extracting numerous active constituents for their pharmacological preparations.

Objective: Isolation of compounds from Euphorbia fusiformis rhizomes and evaluation of extracts and each isolates for its antioxidant and antifungal activities. Results: Five compounds were isolated including Euphol 1, \β-Sitosterol 2, Caudicifolin 3, Scoparone 4 and Scopoletin 5. The occurrence of the compounds 2, 4 and 5 in the herb reported here for the first time. The ethyl acetate extract showed significant antioxidant activity (IC50 = 2.781 mg/ml) and its yielded compound 3 showed moderate antioxidant activity (IC50 = 3.25 mg/ml) using DPPH method. The ethyl acetate extract showed better antifungal activity against Aspergillus niger and Candida albicans. Conclusion: Compounds 2, 4, 5 were isolated first time from this plant. The ethyl acetate extract showed significant antioxidant and antifungal activity against A. nigar and C. Albicans. Thus, this study concludes by demonstrating the isolation, characterization, antioxidant and antifungal properties of E. fusiformis, which may have further therapeutic value.
