Abstract

Five flavonoids isolated from the ethyl acetate fraction of Cedrela sinensis A. Juss. were identified by high performance liquid chromatography. Separation was achieved by reversed phase chromatography on ${\mu}-bondapak$ C18 column with isocratic elution method. The content of the major flavonoid, quercitrin was about 9.48%(w/w) and 37.06%(w/w) for the methanol extract and ethyl acetate fraction, respectively.

참죽나무(Cedrela sinensis A. Juss.) 잎의 ethyl acetate분획으로부터 분리한 5종의 flavonoid성분들은 HPLC에 의한 용매계 THF-dioxane-MeOH-HOAc-5% $H_3PO_4-H_2O$(145 : 125 : 50 : 20 : 2 : 658)에서 양호한 분리능을 나타내었다. 또한 주성분인 quercitrin의 함량은 MeOH엑스 및 EtOAc 분획에서 각각 9.48%(w/w) 및 37.06%(w/w) 함유되어 있음을 알 수 있었다.
