[Quantitative analysis of methoxylated flavonoids in iyo (Citrus iyo) peels by high-performance liquid
Abstract:
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.
