Butyrospermol acetate exhibits inhibitory effect on skin tumor promotion in an in vivo two-stage carcinogenesis test using 7,12-dimethylbenz [a] anthracene (DMBA) as an initiator and TPA as a promoter, the exceptionally high levels of triterpenes in shea fat, indicates that shea nuts and shea fat (shea butter) constitute a significant source of anti-inflammatory and anti-tumor promoting compounds.

To investigate the anti-HBV constituents in the roots of Euphorbia fischeriana. METHODS AND RESULTS:The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis. Some compounds were tested for the anti-HBV activity. Eleven compounds were isolated and identified as tirucalla-5,24-dien-3-ol (1), 24-methyltirucalla-5, 24-dien-3-ol (2), euphol (3), Butyrospermol (4), 24-methylenecycloartenol (5), cycloartenol (6), jolkinolid E (7) helioscopinolide A (8), isoscopoletion (9), dephnoretin (10), and 3, 3'-di-O-methylellagic acid 4'-O-beta-D-xylopyranoside (11). CONCLUSIONS:Compounds 1, 2 and 10 were isolated from the genus Euphorbia for the first time. Compounds 3, 4 and 11 were isolated from this species for the first time. Compounds 1, 8, 9 and 11 showed weak anti-HBsAg and anti-HBeAg activity, while compound 10 showed weak anti-HBsAg activity.
