Title: The research on extracting process of chlorogenic acid from compound Flos Lonicerae
Abstract: To study the compound consist of flos lonicerae,herba taraxaci,fructus forsythiae,herba violae and radix salviae miltiorrhizae.The content of chlorogenic acid was measured by ultraviolet spectrophotomety in 327 waver through the materials were extracted by solvent extraction,ethanol precipitation ,ethanol extraction and process ultrasonic treatment. The contents of chlorogenic acid were 10.0167mg/g,6.9333mg/g,10.0167mg/g,6.9333mg/g respetively,7.4000mg/g,9.6333mg/g;chlorogenic acid yield were32.52%,22.52%,24.03%,31.28%respetively;extractyield:25.3%,18.70%,14.00%,16.40%.Conclusion:the extraction process of water and ultrasonic treatments were optimum.
