  5alpha-Cycloart-24-ene-3,23-dione (1), 5alpha-cycloart-24-ene-3,16,23-trione (2) and methyl 3,4-seco-cycloart-4(28),24-diene-29-hydroxy-23-oxo-3-oate (3), together with five known flavones 5,7,4'-tlihydroxy-3,8-dimethoxyflavone (4), 5,7,4'-trihydroxy-3,8,3'-trimethoxyflavone (5), 5,7,4'-trihydroxy-3,6,8-trimethoxyflavone (6), 5,4'-dihydroxy-3,6,7,8-tetramethoxyflavone (7) and 5,3-dihydroxy-3,6,7,8,4'-pentamethoxyflavone (8) have been isolated from the leaves and twigs of Gardenia obtusifolia. The structures were assigned on the basis of spectroscopic methods. Compounds 3-8 and some of the modified compounds showed significant cytotoxic activities in several mammalian cell lines, especially 8 and its diacetate 21 which exhibited potent cytotoxicities (compound 8: P-388 0.05 mug/mL, KB 0.09 mug/mL, BCA-1 0.63 mug/mL, Lu-1 0.09 mug/mL, ASK 0.70 mug/mL; its diacetate: P-388 0.27 mug/mL, KB 0.06 mug/mL, BCA-1 0.53 mug/mL, Lu-1 0.49 mug/mL). It was also found that 5, 8 and 21 showed antimitotic acitivity in the ASK assay. Compounds 2, 4, 6, 7 and some of the modified compounds displayed interesting anti-HIV activity in the syncytium assay, but were inactive or exhibited weak activity in the HIV-1 RT assay; while compound 3 was found to be active in the HIV-1 RT assay (99.9% inhibition at 200 mug/mL), but cytotoxic in the syncytium assay.

  Abstract From a dichloromethane extract and a hydrolysed methanolic extract from the leaves of Psiadia trinervia, 13 3-methylated flavonols have been isolated. Their structures were established by the usual spectroscopic methods (UV, EIMS, 1H and 13C NMR). Ayanin, casticin, chrysosplenol-D and 5,7,4′-trihydroxy-3,8-dimethoxyfiavone were responsible for the antifungal activity found in the preliminary
