A Study on Determination of Chlorogenic Acid and Cafeine Acid In Buds of Lonicera Macrathiods Hands Maazz
灰毡毛忍冬花蕾中绿原酸和咖啡酸的含量测定

Objective: To scientifically assess the medicinal value of Lonicera Macrathoids Hands-Mazz on the basis of the content of Chlorogenic acid and cafeine acid in it. Method To compare the content of Chlorogenic acid and cafeine acid extracted from Lonicera Macrathoids Hands-Mazz produced in Hunan Province with that extracted from A-class Flos Lonicerae cultivated in Shandong and Henan provinces by the method of high performance liquid chromatography. Result The percentage content of chlorogenic acid in Lonicera Macrathoids Hands-Mazz from the counties of Lonhui, Xupu and Xinning in Hunan Province and that in Flos Lonicerae from Hennan and Shandong provinces of China respectively are as follows: 3.967±0.2724, 2.674±0.1408, 4.514±0.0182, 2.415±0.1913 and 2.104±0.1684 and the percentage content of caffeine acid in them are: 0.0536±0.0063, 0.0424±0.0086, 0.0447±0.0033, 0.0477±0.0023 and 0.0647±0.00645 respectively. Conclusion The content of Chlorogenic acid in the buds of Lonicera Macrathoids Hands-mazz is far or slightly higher than that in A-class Flos Lonicerae and the content of caffeine acid in the former is close to or a little bit higher than that in the latter.
