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.
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.
