Abstract

Methoxylated flavonoids (sinenstin, nobiletin, tangeretin) were isolated and identified by preparative HPLC, mass and NMR. Chung-pi(I) and Chung-pi(II) contained methoxylated flavonoids most richly. Methoxylated flavonoids in Chung-pi obtained from Korean Milgam increased with fruit maturity, while contents of the methoxylated flavonoids gradually decreased after mid of October.

감귤류와 한국산 청피에 함유된 methoxylated flavonoids (sinenstin, nobiletin, tangeretin)를 HPLC, mass 그리고 NMR로 분리하고 분석하였다. Methoxylated flavonoids는 Chung-pi(I)과 Chung-pi(II)에 가장 풍부하게 함유되었다. 한국산 밀감에서 얻어진 Chung-pi(I), (II)의 methoxylated flavonoids 함유량은 밀감성숙도에 따라 증가하였으며, 10월 중순이후에는 서서히 감소하였다.
