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.
