微波炮制对骨碎补中总黄酮及浸出物含量的影响

目的:考察不同炮制方法对骨碎补中有效成分总黄酮及水溶性浸出物含量的影响.方法:用聚酰胺层析-紫外分光光度法测定骨碎补不同炮制品中总黄酮含量;用浸提法测定浸出物的含量.结果:骨碎补经炮制去毛后可以提高总黄酮及浸出物的含量;经砂烫、恒温烘烤及微波炮制后并不影响总黄酮及浸出物的含量.结论:微波法优于其他方法.

Effects of microwave process on total flavonoids and productivity by immersed in Rhizoma Drynaria

AIM: To study the effects of different process methods on the content of total flavonoids and the aqueous extract from Rhizoma Drynariae. METHODS: The contents of total flavonoids of Rhizoma Drynariae processed in different ways were assayed by polyamide chromatography and ultraviolet spectroplotometry; the contents of the aqueous extract were assayed by extraction in water. RESULTS: The contents of total flavonoids and the aqueous extract in Rhizoma Drynariae increased after it was processed and purified. The contents of total flavonoids and the aqueous extract in Rhizoma Dyrnariae hotted in sands, at constant temperature oven and microwave process were not influenced, but easier to be extracted in water by these methods. CONCLUSION:Microwave processis better than the other methods.
