摘　　要：以枣皮粉为试验材料,采用硫代巴比妥酸法(TBA法),探讨红枣可溶性膳食纤维对蛋黄卵磷脂、亚油酸、小鼠肝组织、红细胞膜脂质过氧化体系的影响,研究了红枣可溶性膳食纤维抗脂质过氧化的作用。结果表明:红枣可溶性膳食纤维对脂质过氧化、Fe2+诱发蛋黄卵磷脂脂质过氧化、亚油酸脂质过氧化具有一定的抑制作用,且随可溶性膳食纤维浓度增大,抑制作用逐渐增强;红枣可溶性膳食纤维能够抑制小鼠肝组织的脂质过氧化,对自发性脂质过氧化和Fe2++H2O2诱导肝组织脂质过氧化的抑制作用较强,但对H2O2诱导的肝组织脂质过氧化抑制作用较弱;红枣可溶性膳食纤维对H2O2诱导的红细胞膜脂质过氧化和红细胞膜溶血有一定的保护作用,且呈一定的量效关系。红枣可溶性膳食纤维具有较好的体外抗脂质过氧化能力。To study the anti-lipoperoxidant in vitro of soluble dietary fiber from jujube. With jujube powder as test materials,the effects of soluble dietary fiber on lipid peroxidation system of egg lecithin,linoleic acid,mice liver tissue and erythrocyte membrane was discussed by thiobarbituric acid（ TBA） method.The results showed that,soluble dietary fiber from jujube had inhibition on lipid peroxidation,the yolk lipoprotein peroxidation induced by Fe2＋and linoleic acid peroxidation,and the inhibitory effect was increased with the increase of the concentration of soluble dietary fiber from jujube. Soluble dietary fiber from jujube could inhibit the mice liver lipid peroxidation. The inhibitory effect on spontaneity liver lipid peroxidation and liver lipid peroxidation induced by H2 O2 were stronger,but on liver lipid peroxidation inhibition induced by H2 O2 was weaker. The soluble dietary fiber from jujube had protective function on erythrocyte membrane lipid peroxidation and erythrocytic hemolysis induced by H2 O2,and it showed a doseeffect relationship.From this experiment concluded that,the soluble dietary fiber from jujube had better ability of anti lipid peroxidation in vitro.
