探讨水提法和70%乙醇提取方法对金银花提取物中木犀草苷含量的影响。分别采用水回流法和70%乙醇超声法提取金银花中的木犀草苷,用高压液相色谱仪对两种提取液中的木犀草苷含量进行测定,结果水回流法提取的木犀草苷含量为0.01%,70%乙醇超声法提取的木犀草苷含量为0.061%,70%乙醇超声法提取的木犀草苷含量为水提法的6.1倍。
The effects of water extraction and 70% ethanol extraction on the content of luteolin in the extract of honeysuckle were investigated. Respectively, using water reflux method and 70% ethanol ultrasonic extraction of luteolin in honeysuckle, high pressure liquid chromatography of the two extracts of luteolin in the determination of the results of water reflux extraction method for the content of luteolin The content of luteolin in 0.01%, 70% ethanol ultrasonic method was 0.061%, and the content of luteolin in ultrasonic extraction method of 70% ethanol was 6.1 times of that of water.
