title: [Studies on the chemical constituents of Coleus forskohlii].
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).
  
  
  CONCLUSIONS
  Compounds 1 - 3 are isolated from Coleus genus for the first time, and compound 4 is isolated from C. forskohlii for the first time.
