Abstract:
Glycosides having an excellent sweetness and hydrolysate thereof of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and are each hydrogen, a residue of .beta.-D-glucose, or a residue of an oligosaccharide comprising not more than four D-glucose having 1,2-, 1,4- and/or 1,6-bond, provided that the total number of D-glucose residue in R.sub.1 and R.sub.2 is not more than 6, which is isolated from a fruit of a plant of Cucurbitaceae, particularly Momordica grosvenori Swingle (e.g. Fructus Momordicae) and said hydrolysates are produced by hydrolyzing the glycosides with an enzyme.
