以亚油酸过氧化值为指标，研究了180种东方中草药甲醇提取物在50 ℃贮藏过程中的抗氧化活性。在所测试的草药提取物中，有44种植物对亚油酸的氧化表现出较强的抗氧化活性。在亚油酸甲酯体系中，进一步研究了44种中草药提取物在贮藏35 d时的抗氧化作用。在44种供试植物中，有11种具有特别高的抗氧化作用。研究了不同提取溶剂（甲醇、石油醚和乙酸乙酯）对这11种植物抗氧化活性的影响。大多数草药提取物的抗氧化活性在很大程度上取决于所用的提取溶剂;然而，一些提取物显示出强的抗氧化活性，而不管用于提取的溶剂是什么。[医]补骨脂和狭叶无翅草Sorphora angustifotia Sieb.和Zucc）在75 ℃保持7 d的猪油中进行进一步研究。采用甲醇提取法对紫堇的甲醇提取物进行了分离纯化。和S; angustifolia Sieb.和Zucc。大大降低了猪油在贮藏过程中过氧化物的生成。用0.20%的榛叶提取物处理。对猪油氧化的抑制作用显著强于0.02%丁基羟基茴香醚（P < 0.05）。
Antioxidant activities of methanol extracts of 180 Oriental herbs were studied by determining the peroxide values of linoleic acid during storage at 50 degrees C. Among the herb extracts tested, 44 species showed strong antioxidant sc activities on the oxidation of linoleic acid. The antioxidative effects of these 44 selected herb extracts were studied further in a methyl linoleate system during storage for 35 d. Among the 44 species tested, 11 species had particularly high antioxidative effects. The effects of type of extraction solvent (methanol, petroleum ether and ethyl acetate) on the antioxidant activities of the 11 species were studied. Antioxidant activities of most herb extracts were greatly dependent on the extraction solvent used; however, some of tbe extracts showed strong antioxidant activities regardless of the solvents used for the extraction, Among the 11 herbs selected, based on the antioxidant activity of their methanol extracts, two (i.e., Psoralea corylifolia L. and Sorphora angustifotia Sieb. and Zucc) were selected for fur ther study in lard held at 75 degrees C for 7 d. The methanol extracts of P. corylifolia L. and S; angustifolia Sieb. and Zucc. greatly decreased the peroxide formation of lard during storage. Treatment with 0.20% methanolic extract of Il corylifolia L. exhibited significantly stronger antioxidant effect on the oxidation of lard than treatment with 0.02% butylated hydroxyanisole (P < 0.05).
