摘要
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。
In order to investigate the effects of different extracting methods on cynaroside content in Lonicera japonica Thunb., cynaroside was extracted from Lonicerajaponica Thunb. by water reflux and 70% ethanol, respectively. Then cynaroside content of two extracts were tested by high pressure liquid chromatography. The results showed that cynaroside content was 0.01% in extracts by water reflux method, while it was 0.061% in extracts by 70% ethanol uhrsonic extraction, which was 6.1 times of water extraction.
