摘要:

为了研究月见草Oenothera biennis L.的化学成分,采用硅胶、Sephadex LH-20凝胶、MCI gel CHP-20等柱色谱并结合半制备高效液相等分离技术,利用现代波谱学手段进行化合物结构鉴定。从月见草50%丙酮提取物中分离得到10个化合物,分别鉴定为dimethyl 3-lactyl shikimate(1)、methyl shikimate(2)、3,3′,4-O-三甲基鞣花酸(3)、3,3′-二甲氧基-鞣花酸(4)、3,4,3′-三甲氧基鞣花酸(5)、alternariol 9-methyl ether(6)、2,3-二羟基-1-(4-羟基-3,5-二甲氧基苯基)-1-丙酮(7)、scirpyrone H(8)、dimethoxydimethylphthalide(9)、clearanol C(10)。其中化合物1为新化合物,化合物2~10均为首次从该植物中分离得到。化合物23可显著提高TGF-β1诱导BEAS-2B细胞的活力,推测其具有潜在的肺保护作用。

Abstract:

To study the chemical constituents of Oenothera biennis L..The chemical constituents from 50% acetone extract of the O. biennis were isolated by repeated chromatograph with silica gel,Sephadex LH-20,MCI gel CHP-20 and semi-preparative RP-HPLC.The structure of the separated chemical components was identified by modern spectroscopy identification.Ten compounds were isolated from the ethyl acetate fraction of 50% acetone extract of O. biennis,and identified as dimethyl 3-lactyl shikimate (1),methyl shikimate (2),3,3′,4-O-triomethylellagic acid (3),3,3′-dimethylellagic acid (4),3,4,3′-trimethoxy flavellagic acid (5),alternariol 9-methyl ether (6),2,3-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone (7),scirpyrone H (8),dimethoxydimethylphthalide (9),clearanol C (10).Compound 1 was a new shikimate derivative and compounds 2-10 were newly isolated from the O. biennis. Compounds 2 and 3 could significantly increase the viability of BEAS-2B cells induced by TGF-β1,showing potent lung protection.
