Extensive chromatographic separation and purification of the organic solvent extracts of Nephelium longan (Sapindaceae) stem bark afforded two compounds; scopoletin and stigmasterol. The structures of these compounds were determined by spectroscopic analyses, including 1H and 13C NMR. Different crude extracts (n-hexane, carbon tetrachloride, chloroform and methanol) were tested for antimicrobial activity by standard disc diffusion method known as the Kirby-Bauer method and cytotoxicity was measured by brine shrimp lethality bio-assay. In the brine shrimp lethality bio-assay, the plant extracts showed some promising results as compared to the standard vincristine sulphate, and the test results showed statistical validity. The chloroform and carbon tetrachloride extracts were subjected to antimicrobial and antifungal study and with some exceptions the results are insignificant compared to the standard antibiotic ampicillin. |
