A new dammarane-type triterpene ketone, panaxadione, was isolated from the seeds of Panax ginseng C. A. MEYER (Araliaceae) together with two dammarane-type and lupane-type triterpenes, an aromatic oligoglycoside, three sterol glycosides, and three dammarane-type triterpene oligoglycosides (ginsenosides Rd, Re, and Rg(2)). The structure of a new compound was elucidated on the basis of physicochemical evidence. The relative contents of major ginsenosides in the seeds were compared with those of the flesh parts of young and mature fruits.
从人参（五加科）种子中分离出一种新的达玛烷型三萜酮——人参二醇，同时还分离出两种达玛烷型和羽扇豆烷型三萜、一种芳香寡糖苷、三种甾醇糖苷以及三种达玛烷型三萜寡糖苷（人参皂苷Rd、Re和Rg(2)）。根据理化证据阐明了新化合物的结构。将种子中主要人参皂苷的相对含量与幼果和成熟果实果肉部分的含量进行了比较。
