微波技术对黄芩中黄芩苷浸出量影响的研究

目的：研究微波技术对黄芩中黄芩苷浸出量的影响。方法：对不同浸出方法。药材粒径,浸出时间及微波输出功率进行正交试验。优选黄芩中黄芩苷最佳浸出方案;用紫外分光光度法对黄芩浸出液中黄芩苷含量进行测定。结果：微波技术对黄芩中黄芩苷的浸入量明显优于常规煎煮方法。结论：微波技术应用于药材浸出是一种省时便捷,值得推广普及的中药浸出新方法;半量黄芩粗粉的浸出量优于全量黄芩饮片的浸出量,与中医药理论“煮散减半”相符。

Studies on influence of microwave technique on the amount of baicalin infused from Scutellaria baicalensis.

OBJECTIVE To study the influence of microwave technique on the amount of baicalin infused from Scutellaria Baiacalensis.METHODS With some different infusing methods, powder radius of Chinese medicinal material, diffused time, output power microwave orthogonal test was carried out. Choose the best infusing test design. The amount of baicalin in the Scutellaria baiacalensis infusion was determined by UV.RESULTS Influence of microw ave technique on the amount of baicalin is superior to the general decocting method.CONCLUSION Application of microwave technique in the Chinese medicinal material infusion is a new method which is to save time and worth of spreading out.The amount of baicalin diffused from half amount Scutellaria baiacalensis is larger than total amount of its prepared herbal medicine. The result is coincidence with the traditional Chinese medical theory-"amount of Zhu San(powder decoction)is reduced by half."
