Abstract: Two new ent-kaurenoids, rosthornin C and D, with rosthornin A and B, have been iso- lated from the ethereal extract of the leaves of Rabdosia rosthornii. The chemical structures of the two minor constituents have been established as entu-11α-acetoxy 7β,13β, l9-trihydroxykaur-16-en - l5- one (1 ) and ent- llα-acetoxy-7β, 12β, l4α-trihydroxykaur- 16-en- 15-one (2). respectively, on the basis of detailed spectroscopic analysis, including 2D NMR data.

Key words: Rosthornin C and D
