Anthraquinones in Ketsumeishi samples obtained from various places were quantitatively analysed. After treatment with a mixture of 10% sodium bicarbonate solution, 12% sodium carbonate solution, and 5% sodium hydroxide solution containing 2% ammonia, the absorbance of the alkaline extract at 520 nm was measured using 1,8-dihydroxyanthra-quinone as standard. So far the quantitative estimation of rhein-like anthraquinones is concerned, this method was clearly shown to be superior to conventional ones. Samples of Ketsumeishi from different places of origin may be classified into three groups according to the contents of anthraquinones. The identification of the species according to the contents of rhein-like anthraquinones may also be possible.
