บทคัดย่อ/คำอธิบาย :

Four triterpene acetates, α-amyrin acetate (1a), β-amyrin acetate (2a), lupeol acetate (3a), and bu-tyrospermol acetate (4a), and four triterpene cinnamates, α-amyrin cinnamate (1c), β-amyrin cinnamate (2c), lupeol cinnamate (3c), and butyrospermol cinnamate (4c), were isolated from the kernel fat (n-hexane extract) of the shea tree (Vitellaria paradoxa; Sapotaceae). Upon evaluation of these eight triterpene esters for inhibitory activity against 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation (1 μg/ear) in mice, all of the compounds tested exhibited marked anti-inflammatory activity, with ID 50 values in the range of 0.15-0.75 μmol/ear, and among which compound 3c showed the highest activity with ID 50 of 0.15 μmol/ear. Compound 3c (10 mg/kg) further exhibited anti-inflammatory activity on rat hind paw edema in-duced by carrageenan, with the percentage of inflammation at 1, 3, and 5 h of 35.4, 41.5, and 45.5%, respec-tively. The eight triterpene esters were then evaluated for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) in Raji cells as a primary screening test for inhibitors of tumor promoters. All the com-pounds showed moderate inhibitory effects. Furthermore, compound 3c exhibited 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 biological activities of triterpene acetate and cinnamate esters, together with the exceptionally high levels of these triterpenes in shea fat, indicate that shea nuts and shea fat (shea butter) constitute a significant source of anti-inflammatory and anti-tumor promoting compounds. © 2010 by Japan Oil Chemists' Society.
