Abstract
OBJECTIVE To study the chemical constituents in the aerial parts of Coleus forskohlii. METHODS The compounds were isolated by various column chromatographic methods, and their structures were identified by spectroscopic methods. RESULTS Twelve compounds were isolated and identified as chamaecydin (1), 6 alpha-hydroxydemethylcryptojaponol (2), alpha-cedrene (3), oleanolic acid (4), forskolin G (5), forskolin J (6), 1,6-diacetyl-9-deoxyforskolin (7), forskolin A (8), forskolin H (9), 6-acetyl-1-deoxyforskolin (10), betulinic acid (11), beta-sitosterol (12). CONCLUSION Compounds 1 - 3 are isolated from Coleus genus for the first time, and compound 4 is isolated from C. forskohlii for the first time.
