| 摘 要： | 目的 : 探讨莲房原花青素体内抗氧化机制。方法 : 选用 4月龄 Wistar健康大鼠1 9只 ,按性别、体重随机分成对照组和莲房原花青素组。经口灌胃 1 0 0 mg/kg,3 5 d。结果 : 原花青素组大鼠血清和皮肤组织中 MDA值显著低于对照组 (P<0 .0 5 ) ,而血清和皮肤组织中的 SOD活性、GSH- Px活性和羟脯氨酸 (Hyp)含量均显著高于对照组。结论 : 莲房原花青素能提高大鼠机体抗氧化能力 ,抑制脂质过氧化作用的发生 ,并能增加皮肤中的胶元蛋白含量。

| Abstract: | Objective: To probe into the antioxidation mechanism of lotus seedpod in vivo.Methods:Nineteen 4-month old rats were randomly divided into control group and procyanidins group. After feeding 100 mg/kg LSPC for 35 d, MDA and SOD in skin and serum, GSH-Px and Hyp in blood and skin were measured.Results: MDA levels in skin and serum in the procyanidins group were obviously lower than that of the control(P<0.05); SOD activities in serum and skin, GSH-Px activities in blood and skin were significantly increased; Hyp in serum and skin were significantly increased as compared with control.Conclusion: Lotus seedpod procyanidins could improve the antioxidant capacity in vivo, and inhibit the lipid peroxidation and aging process of the skin. |
