EFFECT OF BEE POLLEN AND ITS ALCOHOL EXTRACT ON LIP1D PEROXIDATION IN VIVO AND IN VITRO / 营养学报

ABSTRACT

The effect of bee pollen of Brassica campestris L. and its alcohol extract on lipid peroxidation was observed in vivo and in vitro.The results showed that the production of lipid peroxides in normal liver hotnogenate of mice and elevation of production of lipid peroxides induced by cysteine and FeSO4 in homogenate were found to be inhibited significantly by in vitro addition of alcohol extract of bee pollen.The elevation of lipid peroxides in serum and liver in adult mice induced by alloxan 75 mg/kg(iv)or by administration of peroxidized corn oil 0.2 ml/mouse was markedly inhibited by oral administration of bee pollen (10 g? kg-1?d-1)for 20 days as compared with respective control groups.The level of lipid peroxide in geriatric mice was also markedly lowered by oral administration of bee pollen (10 g?kg-1?d-1)for 3 months as compared to non-treated geriatric mice.Based on the above in vitro and in vivo experimental results, it may be suggested that bee pollen and its alcohol extract protect tissues against destruction by lipid peroxides.
