Abstract

The seasonal variation of two flavonoid, quercitrin and afzelin, in the leaves of Cedrela sinensis A. Juss. from May until November was investigated by high performance liquid chromatography. Separation by reversed phase chromatography on ${\mu}-Bondapak\;C_{18}$ column was achieved by isocratic elution. The concentration of quercitrin was 5.81% (w/w) in May and high in July(8.89%, w/w), August(7.94%, w/w), and decreased from September to November. The content of another flavonoid, afzelin was 0.06% (w/w) in May and highest in June (0.12%, w/w), and was reduced from July.

참축나무잎 flavonoid들을 column chromatography로서 분리하여 HPLC를 이용하여 화합물을 분석하고 주성분인 quercitrin 및 afzelin을 계절별로 채집, 함유량을 정량하였다. 참죽나무잎 중의 flavonoid는 주 성분인 quercitrin은 채집 초기인 5월을 시작으로 증가되다가 7월과 8월에 7.94, 8.89%로서 최대치에 달하며 9월 부터 감소하는 경향을 보였다. Afzelin의 함유량도 6월에 0.12%로서 최고조에 달하며 7, 8월에 0.09, 0.08%로 많은 양을 함유하다가 가을철인 9월 부터 점점 감소함을 관찰할 수 있다. 따라서 참죽나무잎의 flavonoid 함유량은 여름에 최고조로 달하며 동일나무에서 그의 함량은 일정하지 않고 계절에 따라 변화함을 관찰할 수 있다.
