黑桑椹的营养成分和抗氧化作用的研究

Study on Nutritional Components of Black Mulberry Fruit and Effects on Anti-oxidation

本文分析了山西地产黑桑椹的13种微量无素和VC、VE、β-胡萝卜素、黄酮等多种营养成分,并观察了其对大鼠机体脂质过氧化作用和果蝇寿命的影响。用10%桑椹鲜果或原汁饲喂大鼠8w,可显著降低大鼠血浆和肝脏组织中脂质过氧化产物丙二醛(MAD)含量及肝脏中脂褐素含量(p<0.05～0.01),增加超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-Px)的活性(p<0.05～0.01)。黑桑椹能显著延长果蝇寿命(p<0.05～0.01)。

We analyzed the nutritional components of black mulberry fruit（Morus alba L.） in Shanxi Province, China. It was found to contain VC, VE, β-caroten, rutin, myricetin, morin, quercetin, Fe, Mn, Zn,Se, et al. The juice was extracted from the black mulberry fruit. After being fed on the diet with 10% fresh mulberry fruits or juice for 8 weeks, male Wistar rats showed significantly reduced MDA and increased SOD and GSH-Px in blood and liver （p 〈 0.05-0.01）. and decreased the lipofuscin in liver（p 〈 0.05-0.01）. Fresh black mulberry fruits or juice could prolong the life span and improve the flying ability of Drosophila melanogaster （p 〈 0.05-0.01）. The results showed that the mulberry fruit has evident antioxidation effects. It is worth further researching and exploiting.
