Abstract:
Investigation of the leaves and twigs of Callicarpa longissima resulted in the isolation of four new compounds (1-4), callilongisins A-D, and five known compounds, ursolic acid, 3-oxoanticopalic acid, (E)-6β-hydroxylabda-8(17),13-dien-15-oic acid, 5-hydroxy-3,6,7,4'-tetramethoxyflavone, and artemetin. Compounds 1-3 are 3,4-seco-abietane-type diterpenoids, and compound 4 is an analogue of a labdenoic-type diterpene. The structure of compound 1 was confirmed by X-ray crystallographic analysis. Cytotoxicity against a human prostate cancer cell line (PC3) and anti-inflammatory activities of the isolated compounds were evaluated.
