对北五味子的化学成分进行研究,分离得到10个化合物.通过波谱分析技术(1H NMR、13C NMR)及比对文献资料的方法进行结构鉴定,这10个化合物分别为12-当归酰基-五味子二内酯Ⅰ(1)、五味子二内酯Ⅰ(2)、五味子二内酯G(3)、去氧五味子素(4)、 sasanquin (5)、地衣酚-O-β-D-吡喃葡萄糖苷(6)、奥卡宁-4-甲基醚-3'-O-β-D-吡喃葡萄糖苷(7)、扁枝衣二酸(8)、juglansol A (9)、苯甲酸-2-乙酰氧基苄酯(10).化合物1为新化合物,化合物6-10为首次从五味子中分离得到.“,”A new 18-norschiartane bisnortriterpenoid,12-angeloyl wuweizidilactone I (1) and nine known compounds,wuweizidilactone I (2),wuweizidilactone G (3),deoxychizandrin (4),sasanquin (5),orcinol-O-β-D-glucopyranoside (6),okanin-4-methyl ether-3'-O-β-D-glucopyranoside (7),evemic acid (8),juglansol A (9) and 2-acetoxybenzyl benzoate (10),were isolated from the fruits of Schisandra Chinensis.Their structures were established by a combination of spectroscopic data analysis in addition to comparison with literature data.Compound 1 was new,and compounds 6-10 were isolated from Schisandrae Chinensis for the first time.
