超声醇溶-紫外分光光度法测定不同产地三七花中总黄酮含量
Ultrasonic sound ethanol dissolve-ultraviolet spectrophotometric determination of total flavones in Panax notoginseng flowers from different areas
摘要
Abstract
A comparative analysis of the total flavones content in Panax notoginseng flowers from different areas was performed. The total flavones content in Panax notoginseng flowers was determined at 508nm by ultraviolet spectrophotometric with rutin as the reference substance. Based on the experiment of single factor, the optimum extraction conditions were as follow: ethanol concentration 60% , ratio of liquid to solid 1 :25, extraction time 1h. Total flavones in Panax notoginseng flowers from different areas were compared and highest content was 0. 73% , the lowest was only 0.43%. The repetition, stability and precision of the method in analyzing the total flavones content are promising.The method can be used to control the quality of Panax notoginseng flowers.关键词
