7-Oxodihydrokarounidiol [7-oxo-D:C-friedo-olean-8-ene-3α,29-diol], novel triterpene from Trichosanthes kirilowii

Akihisa,Kokke,Tamura,Nambara

, p. 1199 - 1202 (2007/10/02)

The structure of 7-oxodihydrokarounidiol [7-oxo-D:C-friedo-olean-8-ene-3α,29-diol], isolated from the seeds of Trichosanthes kirilowii (Cucurbitaceae), was determined by chemical correlation with karounidiol [D:C-friedo-oleana-7,9(11)-diene-3α,29-diol] from the same source. Two other natural products, viz. bryonolic acid (3β-hydroxy-D:C-friedo-olean-8-en-29-oic acid) and bryononic acid (3-oxo-D:C-friedo-olean-8-en-29-oic acid), were also correlated with karounidiol.
