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