Abstract

PURPOSE: To prepare a saponin derivative useful as a raw material of other compounds and known saponin compounds, by eliminting at least one saccharide from the substutuent at a specific position by the enzymatic hydrolysis of saponin, and purifying and separating the products.
CONSTITUTION: A novel saponin of formula (when R1 is [β-D-glucopyranosyl(1- →2)-α-L-rhamno-pyranosyl(1→6)]-β-D-glucopyranosyl group, then R2 is H, β-D- glucopyranosyl(1→6)-β-D-glucopyranosyl group, etc. and R3 is H, hydroxyl group, etc.) is made to contact with a hydrolase capable of braking the O-glycoside bond, e.g. hesperidinase, maltase, cellulase, etc. By this treatment, at least one saccharide is removed from the substituent group at the 3- and/or 20-position of the compound of formula. If necessary, the product is separated and purified.
