高良姜温中散寒、行气止痛,是一种重要的温热性药物,其中含有的黄酮类化合物主要为槲皮素。槲皮素的测定方法通常有分光光度法、荧光法、光度法和色谱法等,但测定手续较为繁琐。高良姜中槲皮素的电化学方法测定,迄今未见报道。我们采用差示脉冲极谱法测定高良姜中的槲皮素,灵敏度高、方法简便。毋须分离手续,可以在样品提取液中直接测定,结果良好。本法还可适用于其他含黄酮类化合物的中草药分
Galangal warm in the cold, qi and pain, is an important warming drugs, which contain mainly flavonoids quercetin. Quercetin determination usually spectrophotometry, fluorescence, spectrophotometry and chromatography, but the determination of the procedure is more complicated. Electro-chemical determination of quercetin in galangal has not been reported. We use differential pulse polarography determination of Quercetin galangin, high sensitivity, the method is simple. Without separation procedures, can be measured directly in the sample extract, the result is good. This law can also be applied to other herbal ingredients containing flavonoids
