Abstract
|
|
|
|
A new nortriterpene, rhombenone (1) was isolated from the leaves of Hedera rhombea Bean (Araliaceae). The structure of this compound was established as 27-demethyl-20(S)-dammar-23-ene-, 20-diol-3, 25-dione on the basis of spectral analysis including HMQC and HMBC techniques. Rhombenone (1) was the first 27-demethyl nortriterpene of dammarane type isolated from natural sources.
