Abstract: A novel 18-nor-clerodane diterpenoid named sagitone (1) was isolated from the 95% ethanol extract of dry roots of Tinospora sagittata var. yunnanensis together with the five known diterpenoids columbin (2), palmatoside C (3), fibleucin (4), tinophylloloside (5) and epitinophylloloside (6). The structure of the new compound 1 was determined based on MS, IR, 1D and 2D NMR spectral data. The compounds 1~6 did not show significant cytotoxic activity against cancer cell lines K562 and HL-60.
Keywords: Tinospora sagittata var. Yunnanensis; clerodane diterpenoid; sagitone; cytotoxic activity
