익모초의 계절 및 지역별 Rutin 함량변화 연구

Abstract

In a pattern analysis of GC-MS of 21 Leonuri herba samples harvested in China and Korea, characteristic differences were observed between Chinese and Korean samples. specifically, Leonuri herba form Hanllasan showed unusual retention time. Rutin was employed as a standard compound of Leonuri herba. All samples had 0.32±0.18 (%) rutin contents in average, but Korean samples had more rutin than Chinese one, especially the sample from Hanllasan of Jeju showed highest rutin content (3.2%). In rutin contents of seasonal variation, there were more rutin contents in after blooming, 2 years aged Leonuri herba than before.
