Liquid chromatographic methods Separation and quantitative analysis of theaflavins and thearubigens has also been achieved by gel permeation chromatography on Sephadex LH-20, monitoring the eluting peaks at 380 nm. Reversed-phase LC separation has also been conducted using a Cig column, with a mobile phase consisting of 29% aqueous acetone and 1% acetic acid. [Pg.1530]
