Abstract

Two new norlignan derivatives, crassifoside I (1) and sinensigenin C (2), were isolated from the rhizomes of Curculigo capitulate, along with six known norlignan derivatives, 1,1-bis(3,4-dihydroxyphenyl)-1-(2-furan)-methane (3), crassifogenin B (4), crassifoside A (5), breviscaside A (6), crassifoside D (7), and curcapital (8). Their structures were elucidated on the basis of spectral evidence and comparisons with literature data. The 1H and 13C NMR data of compound 3 was first assigned. Compounds 3-7 were isolated from this plant for the first time.

摘要

两种新的木脂素衍生物，crassifoside I（1）和sinensigenin C（2），从 Curculigo capitulate 的根茎中分离出来，此外还有六种已知的木脂素衍生物，1,1-双（3,4-二羟基苯基）-1-（2-呋喃）-甲烷（3），cras sifogenin B（4），cras sifoside A（5），breviscaside A（6），cras sifoside D（7）和 curcapital（8）。基于光谱证据和与文献数据的比较，确定了它们的结构。首次分配了化合物 3 的 1H 和 13C NMR 数据。化合物 3-7 也是首次从该植物中分离得到。
