columns including silica gel, ODS, D101 resin, Sephadex LH-20 and HPLC, to yield three new diarylheptanoids (1-3) and two novel stilbenes (4 and 5), together with six known ones (6-11). Their structures were elucidated on the basis of extensive 1D NMR (1H and 13C), 2D NMR (COSY, HSQC, HMBC, NOESY), IR, and MS spectroscopic data analyses. Moreover, the in vitro bioactivity screening experiment suggested that
将薯os根茎的70%乙醇提取物进行色谱柱处理,包括硅胶,ODS,D101树脂,Sephadex LH-20和HPLC,得到三个新的二芳基庚烷类化合物(1-3)和两个新的对苯二酚(4和5)以及六个已知的(6-11)。在广泛的1D NMR(1H和13C),2D NMR(COSY,HSQC,HMBC,NOESY),IR和MS光谱数据分析的基础上阐明了它们的结构。此外,体外生物活性筛选实验表明,化合物6-8和10可以显着增加分化的L6肌管中的葡萄糖消耗,而2,9-11在HepG2细胞中显示出甘油三酸酯抑制作用。
