The quantitative analysis of eight kinds of methoxylated flavonoids in Citrus iyo HORT. ex TANAKA (Rutaceae) was examined by high-performance liquid chromatography. These compounds could be determined within 50 min on C-18 reversed-phase column. Elution system was carried out with a mixture of 1, 4-dioxane-water-acetic acid in ratios of 2 : 7 : 1 and 7 : 2 : 1 in the form of a gradient from 8 : 2 to 2 : 8 for 60 min.
