GC-MS Analysis on Form and Content of Phytosterol in the Beans from Different Producing Areas

This paper established the GC-MS method to analyze phytosterol in beans and study the content and distribution of phytosterol in green beans,red beans,black beans and soybeans in 5 main producing areas of China(Inner Mongolia,Heilongjiang,Jilin,Hebei,Shandong).This paper used GC-MS method to analyze the content and distribution of campesterol,stigmasterol,sitostanol,brassicasterol,ergosterol,cycloartanol,cycloartenol,2,4-methylenecycloartanol,spinasterol,cholesterol and cholestanol in the beans from different producing areas.Results showed that the content of sterol in green beans was higher than in three other kinds of beans,and the content of sterol in red beans was the lowest.Different producing areas had a significant impact on the content of sterol in beans,and the dominant producing areas included Inner Mongolia and Heilongjiang.The study provided a basis for quality assessment and nutritional evaluation of beans and provided a reference for traceability and variety distinction study of other edible beans.
