The regulatory effects of blood glucose, lipid metabolism and free radical elimination were compared in streptozotocin-induced hyperglycemic rats among the following treatments: Ginkgo biloba leaf extract (EGB), the biotransformation of EGB by Hericium erinaceus, a cultural filtrate of H.erinaceus, and the cultural filtrate of H.erinaceus plus EGB, together with the normal control, the model control and the positive control (Metformin). The best results were obtained from the biotransformation treatment group, which could significantly reduce the levels of blood glucose and fructosamine. However, the treatment did not increase the blood insulin level. The EGB transformed products could obviously increase the serum superoxide dismutase activity and reduce the malondialdehyde level, but the reduction of malondialdehyde was not obvious as compared with that of the other treatment groups. This study provides a useful information on improving the medical properties of the herb extracts by biotransformation. 相似文献

银杏叶提取物猴头菌转化前后降血糖作用的比较研究 总被引:1,自引:1,他引:0
以正常对照组、模型对照组和阳性(二甲双胍)对照组为参照,试验比较了银杏叶提取物(EGB)、猴头菌转化EGB的产物、猴头菌发酵液、猴头菌发酵液中添加EGB对链脲佐菌素诱导的2型糖尿病模型大鼠血糖和血脂代谢的调节作用以及对自由基清除作用。结果显示:相对于其他给药组,猴头菌转化EGB的转化产物能更加显著地降低糖尿病模型大鼠的血糖和果糖胺水平,但是对胰岛素水平无显著的调节作用,与模型对照组和其他给药组相比,EGB转化产物可以显著提高超氧化物岐化酶活性;与模型对照组相比亦可显著降低丙二醛水平,但与其他给药组相比其降丙二醛作用差异不明显。本项研究对采用微生物转化法提高植物提取物药用效果提供了参考资料。 相似文献
