摘要:

利用质谱引导的自动纯化分离系统对垫状卷柏95%乙醇提取物的乙酸乙酯萃取部分进行选择性分离纯化双黄酮类、炔酚类化合物。并利用MS、1H NMR、13C NMR、2D NMR等光波谱分析方法确定结构,结果得到四个双黄酮类化合物,分别为扁柏双黄酮(1)、异柳杉双黄酮(2)、苏铁双黄酮(3)、穗花杉双黄酮(4),七个炔酚类化合物,分别为selaginellin(5)、selaginpulvilin A(6)、selaginpulvilin B(7)、selaginellin O(8)、selaginellin E(9)、selaginellin A(10)、selaginellin B(11)。采用MTT法评价了化合物1~11体外抑制人非小细胞肺癌细胞(NSCLC) H322增殖活性,结果表明,除化合物47外,其他化合物对人非小细胞肺癌细胞H322有不同程度的增殖抑制活性,其中化合物310抑制作用较强,IC50值分别为16.70和9.54 μmol/L。

Abstract:

Targeting isolation of biflavonoids and selaginellin derivatives from Selaginella pulvinata (Hook.& Grev.) Maxim. was investagated by was performed on a Waters preparative LC-MS autopurification system and the ethyl acetate part of the 95% ethanol extract of S. pulvinata was separated and purified. The chemical structures of the separated compounds were identified by MS,1H NMR,13C NMR,2D NMR and spectral analysis methods. Four biflavonoids were isolated and identified as hinokiflavone (1),isocryptomerin (2),sotetsuflavone (3) and amentoflavone (4). Seven selaginellin derivatives were obtained and identified as selaginellin (5),selaginpulvilin A (6),selaginpulvilin B (7),selaginellin O (8),selaginellin E (9),selaginellin A (10) and selaginellin B (11). The MTT assay was used to evaluate the inhibitory effect of compounds 1~11 on the proliferation of human non-small cell lung cancer cell line (NSCLC) H322 in vitro. The results showed that compounds 1,2,3,5,6,8,9,10 and 11 had different degrees of inhibitory activity on human NSCLC cell line H322. Compounds 3 and 10 had stronger inhibitory activity on human NSCLC cell line H322,with IC50 values of 16.70 μmol/L and 9.54 μmol/L,respectively.
