GC MS ANALYSIS AND ANTIMICROBIAL ACTIVITY OF SEED OIL OF BROUSSONETIA PAPYRIFERA (L.) VENTAbstract
The current study focuses on evaluating chemical composition and antimicrobial activity of seed oil of Broussonetia papyrifera; a widely used Chinese medicinal plant. The chemical constituents of the oil were evaluated by GC‑MS analysis. Antimicrobial activity and minimum inhibitory concentrations were determined by disk diffusion and agar dilution methods. The seed oil contains 46 different phytoconstituents where major compounds were hexadecanoic acid (43.6%), heptadecene‑8‑carbonic acid (17.5%) and caryophyllene (8.4%). Seed oil exhibited inhibitory effect on Staphylococcus aureus, Proteus vulgaris, Bacillus cereus, and Enterobacter aerogenes, while it showed no such inhibitory effect on fungal strains. The studies revealed that majority of the compounds in oil were saturated fatty acids and their derivatives. The oil possessed significant antibacterial activity against selected bacterial strains while tested fungal strains were completely resistant to B. papyrifera seed oil.
