摘要
目的:研究半夏Pinellia ternata鲜块茎中的生物活性成分,为其质量评价提供科学依据。方法:采用多种柱色谱方法进行分离纯化,根据理化性质和谱学方法鉴定其结构。利用微孔板紫外吸收比色法,体外测定化合物对脂多糖(LPS)刺激的小鼠腹腔巨噬细胞产生肿瘤坏死因子TNF-α的抑制作用。结果:从半夏鲜块茎中分离得到9个化合物,分别鉴定为反式-对-香豆醇(1),3,4-二羟基桂皮醇(2),阿魏酸(3),落叶松脂醇(4),赤式-1-(4-羟基-3-甲氧基苯基)-2-{2,6-二甲氧基-4-[1-(E)-丙稀-3-醇]-苯氧基}-丙烷-1,3-二醇(5),去氢二松柏醇(6),异落叶松脂醇(7),4-羟苯丙烯基-O-β-D-吡喃葡糖苷(8)和松柏苷(9)。化合物1,2,3,8和9在10~mol·L^-1浓度对LPS刺激的小鼠腹腔巨噬细胞产生TNF-α的抑制作用分别为24.1%,57.6%,40.2%,82.7%和62.0%。结论:化合物1,2和4~8系首次从半夏属植物分离得到,化合物9系首次从半夏分离得到。化合物1,2,8和9为苯丙素类化合物,化合物4~7为木脂素类化合物。半夏的抗炎作用可能与化合物1,2,3,8和9有关。
Objective: To study the bioactive constituents of the fresh rhizome of Pinellia ternata, and provide the scientific basis for quality control. Method: Various chromatographic techniques were used to separate and purify the chemical constituents, and their chemical structures were determined on the basis of physical-chemical properties and spectroscopic analysis. The inhibitory effects of the isolated compounds on tumor necrosis factor (TNF)-α production in the peritoneal macrophages of mice stimulated with lipopolysaccharide (LPS) were assayed in vitro by microplate colorimetric method. Result: Nine compounds were isolated and identified as (E)-p-coumaryl alcohol (1), 3, 4-dihydroxycinnamyl alcohol (2), ferulic acid (3), lariciresinol (4), erythro-guaiacylglycerol-β-O- 4'-sinapyl ether (5), dehydrodiconiferyl alcohol (6), isolariciresinol (7), sachaliside 1 (8) and coniferin (9). The inhibitory effect of compounds 1, 2, 3, 8, and 9 were 24. 1%, 57. 6%, 40. 2%, 82. 7%, and 62. 0%, respectively, against the TNF-α production in the peritoneal macrophages of mice stimulated with LPS at a concentration of 10 -5 mol . L^-1 in vitro. Conclusion: The compounds 1, 2 and 4-8 from genera Pinellia Ten. and compound 9 from P. ternata were isolated for the flint time. The compounds 1, 2, 8 and 9 were phenylpropanoids, and 4-7 were lignanoids. The anti-inflammatory effects of the rhizome of P. ternata might relate at the least to compounds 1, 2, 3, 8 and 9.
