摘要:
从五味子果实中分离出四种新的二苯并环辛二烯木脂素,分别命名为(-)-大黄素 L1 (6)和 L3 (7)、(±)-大黄素 M1 (8)和(+)-大黄素 M2 (9)。(五味子科)果实中分离得到。通过化学和光谱研究阐明了它们的绝对结构。Kochetkov 等人和 Liu 等人也根据化学和光谱研究阐明了 γ-五味子素(1,dl-form)的立体结构,其平面结构已被 Kochetkov 等人和 Liu 等人提出。

摘要:
Five new lignans, schisantherins L-0 and acetylschisantherin L, were isolated from the seeds of Kadsura coccinea. Their structures, including absolute configurations, were elucidated by spectroscopic analysis and chemical conversions.
The Constituents of Schizandra chinensis Baill. X. The Structures of .GAMMA.-schizandrin and four new lignans,(-)-gomisins L1 and L2,(.+-.)-gomisin M1 and (+)-gomisin M2.
Four new dibenzocyclooctadiene lignans, named (-)-gomisins L1 (6) and L3 (7), (±)-gomisin M1 (8) and (+)-gomisin M2 (9), were isolated from the fruits of Schizandra chinensis BAILL. (Schizandraceae). Their absolute structures were elucidated by means of chemical and spectral studies. The stereostructure of γ-schizandrin (1, dl-form), the plane structure of which had already been suggested by Kochetkov et al. and Liu et al., was also elucidated on the basis of chemical and spectral studies.
