摘    要:目的:研究绒毛诃子果实中多酚类化学成分及其抗氧化活性。方法:采用ToyopearlHW-40和MCIgelCHP-20P柱分离并结合制备型高效液相色谱,对诃子70%丙酮提取部分进行分离纯化,利用MS、1H—NMR和13C·NMR进行结构鉴定;以紫外分光光度法测定诃子多酚类对DPPH’和ABTS。的清除率。结果:从诃子果实中分离鉴定了9个化合物,分别鉴定为:诃黎勒酸(1)、诃子酸(2)、1,3,4,6-四-O-没食子酰-/3-D-葡萄糖苷(3)、1,3,6-三-O-没食子酰-β-D-葡萄糖苷(4)、没食子酸(5)、诃子素(6)、1,2,3,4,6一五-O-没食子酰巾-D-葡萄糖苷(7)、新诃黎勒鞣花酸甲酯(8)、新诃黎勒鞣花酸酯(9)。其中4、8为首次从诃子中分离得到。抗氧化实验中,化合物4的TEAC值为(3.912±0.21)mmol·g-1,抗氧化活性最强,与其他单体化合物比较,差异具有统计学意义(P〈0.01),化合物3、5和6的TEAC值与对照品维生素c接近,有较强的抗氧化活性,与对照组比较差异没有统计学意义,但是与其他化合物比较差异具有统计学意义(P〈0.01),化合物8的抗氧化活性最低。

关 键 词:鞣质  NMR  诃子果实  抗氧化

Abstract:Objective: To study polyphenolic compounds from fruits of Terminalia chebula Retz. vat. tomentella Kurt. and their antioxidant activity. Methods: Macroporous resin(Toyopearl HW-40 and MCI gel CHP-20P) columns and preparative HPLC were used, compound structures were determined by MS, NMR, COSY and HMBC techniques. The antioxidant activities of the polyphenolic compounds were assayed based on the method of DPPH and ABTS, which can evaluate the antioxidant ability in vitro. Results: Nine compounds were isolated and identified as chebulinic acid (1), chebulagic acid (2), 1, 3, 4, 6-tetra-O-galloyl-β-D-glucose (3), 1, 3, 6-tri- O-galloyl-β-D-glucose( 4 ), gallic acid ( 5 ), terchebin ( 6 ), 1, 2, 3, 4, 6-penta-O-galloyl-β-D-glucose ( 7 ), methyl neochebulinate (8), neochebulinate (9) . Conclusion: Compounds 4 and 8 were isolated for the frist time from the fruits of T. chebula. Compounds 3, 4 and 5 have obvious antioxidant activity compared with control group. The antioxidant activity of crude extract was lower than single compounds.
Keywords:Hydrolyzable tannins  NMR  Terminalia chebula Retz. var. tomentella Kurt.  Antioxidant activity
