초록

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.

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.
