Study on the Seasonal and Regional Variation of Rutin Content of Leonuri Herba

In a pattern analysis of GC-MS of 21 Leonuri herba samples harvested in China and Korea, characteristic differenced 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.
