Sesquiterpene lactones from Diaspananthus uniflorus (SCH. BIP.) KITAM.
摘要:
从 Diaspananthus uniflorus (SCH. BIP.) KITAM.(菊科)中分离出五种新的愈创木型倍半萜内酯,即 diaspanolides A (V)和 B (VI),以及 diaspanosides A (VIII)、B (IX)和 C (X)。(Compositae)中分离出来,同时分离出的还有五种已知化合物:costunolide (I)、reynosin (II)、dehydrocostuslactone (III)、11, 13α-dihydrozaluzanin C (IV) 和 glucozaluzanin C (VII)。这些化合物的结构是根据光谱数据和一些化学变化确定的。

Five new guaiane-type sesquiterpene lactones, diaspanolides A (V) and B (VI) and diaspanosides A (VIII), B (IX) and C (X), have been isolated from Diaspananthus uniflorus (SCH. BIP.) KITAM. (Compositae), together with five known compounds, costunolide (I), reynosin (II), dehydrocostuslactone (III), 11, 13α-dihydrozaluzanin C (IV) and glucozaluzanin C (VII). The structures were determined on the basis of spectral data and some chemical transformations.
