本文继续报道从湖北房县中坝采集的一种南五味子(Kadsura sp.种名待定)根中分得的另外三个木脂素类新化合物:五味子酯(schisantherin)G(1),H(2),I(3)和六个已知物:schizandronic acid,isoschizandrolic acid,kadsurarin(1a),veraguensin,β-谷甾醇和硬脂酸的分离,鉴定与结构研究.同时报道在结构研究中获得的八个衍生物:1b,1c,1d,2a,2b,3a,3b和3c的理化数据以及kadsuraxin(1a)的绝对构型. This article continues to report on three new lignan class compounds derived from the root of a Kadsura sp. Collected from Fangba, Fangxian County, Hubei Province: schisantherin G (1), H ( 2), I (3) and six known compounds: schizandronic acid, isoschizandrolic acid, kadsurarin (1a), veraguensin, β-sitosterol and stearic acid separation, identification and structural studies also reported in the structural studies obtained Of the eight derivatives: the physicochemical data of 1b, 1c, 1d, 2a, 2b, 3a, 3b and 3c and the absolute configuration of kadsuraxin (1a).
