Abstract

The whole plant of Ajuga bracteosa afforded five compounds including one new clerodane diterpenoid designated as Bracteonin-A ( 1 ) 6 f -acetoxy, 15 (R&S)-methoxy, 18-(4'-hydroxy, 3'- g -methyl, 3'- f -acetoxy, butyryloxy) neoclerodane. The other compounds identified were 14,15-dihydroajugapitin, 14-hydro-15-hydroxy ajugapitin, g -sitosterol, and stigmasterol. The structural elucidation was carried out by spectroscopic techniques.
