Santonin content in Artemisia kurramensis Quaz. can be determined by extracting the plant material with barium hydroxide, acidification of the baryta extract with hydrochloric acid, shaken with chloroform, and purifying the finally obtained chloroform solution of santonin, or chloroform extract of this plant itself by passage through an adsorption column filled with activated alumina or carbon, and finally by colorimetric determination with sodium methoxide. The sample required for this method is 0.1g. and the procedures are so simple that it can be adopted for the detection of the variation of santonin content during growth or in various parts of the plant body.
