ABSTRACT:
A method for producing high purity sterol glycosides which is characterized by selecting a most suitable raw material from among raw materials, by making use of free sterols coexistent in said raw materials, as an indication for the selection; extracting a mixture of sterol glycosides from the selected raw material; turning the resulting extract into their tetracetates; thereafter separating an objective fraction alone according to a liquid chromatography; and hydrolyzing this fraction to obtain the original sterol glycosides.
