Study on Extraction Process of Inositol from Ceratonia siliqua

[ Objective ] The optimum extraction process is probed to inositol from Ceratonia siliqua. [ Method ] The impact of different sol- vents, extraction temperature and extraction time on the yield of inositol were investigated ; by using orthogonal test method optimum purifica- tion process are determined from the raw extracts, and quantitative analysis of inositol from Ceratonia siliqua was made by GC. [ Result ] The optimum extraction process of inositol from Ceratonia siliqua was as follows ： the ethanol concentration is 40%, the temperature is 80 ℃, the extraction time is 3 h ; the optimum hydrolytic condition is pH 4.5, concentration of phytase is 4. 0%, hydrolytic temperature is 40 ℃ And the content of inositol attains 10.76% after purification. [ Conclusion] The research provides foundation for extracting the inositol from Cerato- nia siliqua.
