Abstract: The preparation and purification of mixed plant sterol standard sample by a recrystallization method were studied.Best solvents and operate conditions were found .The experimental results showed that the total content of plant sterol washigher than 99% and the total yield was higher than 55% after the third recrystallization operation. The applications of mixedplant sterol standard sample in quantitative analysis by gas chromatography were studied. These methods were found convenient,short-cut, cheap and practical.
Key words: plant sterol, standard, recrystallization, gas chromatography
