Diterpenoid constituents from Rabdosia rosthornii.[Reference: WebLink]

METHODS AND RESULTS:
Two new diterpenoids having an ent-kaurene skeleton, rosthornin A(1) and Rosthornin B (2), have been isolated from the ethereal extract of the dried leaves of Rabdosia rosthornii. Their chemical structures have been suggested as ent- 11α-acetoxy-13β,19-dihydroxykaur-16-en-15-one (1)and ent-11α,19-diacetoxy -7β,13β-dihydroxykaur -16-en-15-one (2) respectively on the basis of biogenesis, detailed spectroscopic analysis (COSY) and chemical conversions.
