Medicinal plants play an important role for health care. Medicinal plants have ability to cure both infectious and non infectious diseases. According to an estimate about 25 % of medicines are derived from plants. The objective of the present study was to evaluate the antifungal activity of Feronia elephantum Correa by using Agar well diffusion assay. The fungal strains used in this research work were Aspergillus niger, Penicillium exspansum, Candida albicans and Fusarium oxysporum. The length of inhibition zone was measured in millimetres. The results were referenced against Glucanazole antifungal agent. Methanolic fruit extract showed maximum antifungal activity against most of the strains where as moderate antifungal potential was shown by leaf extract in aqueous extract.
The roots of Citrus sinensis have yielded a flavanoid glycoside. The compound was characterized as dihydrokaempferol 7,4’-dimethyl ether-3-O-α-rhamnopyranosyl(1”’→ 6”)-β-glucopyranoside on the basis of U.V, I.R and N.M.R (1H, 13C).
Phellodendron amurense Rupr. (amur cork tree, Rutaceae), a strong tree, native to Eastern Asia, it is cultivated in Europe and America as a decorative plant. Phellodendri cortex contains alkaloids, limonoids, phenolic compounds and polysaccharides. It is used as antiinflammatory, antineuralgic and antidiabetic agent in stomach diseases in Far East Medicine. Air-dried fruits contain 1.9% of essential oil. Monoterpene and sesquiterpene hydrocarbons were investigated. Hydrocarbon fractions were isolated by vacuum distillation and flash chromatography. Components of fractions were identified by GC, GC/MS, and 'H-NMR spectroscopy. Fifteen monoterpene hydrocarbons representing 72% of the oil with myrcene (67,3%) and nineteen sesquiterpene hydrocarbons representing 1 1% of the oil with ß-caryophyllene (7.0%) and germacrene D (1.6%), were identified.
