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.
Claims9
A compound of the formula:
- ##STR3## 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-glucoses having 1,2- 1,4- and/or 1,6-bond, provided that the total number of the D-glucose residue in R.sub.1 and R.sub.2 is not more than 6 and provided that both R.sub.1 and R.sub.2 are not both hydrogen at the same time.
A sweetening agent comprising a compound of the formula:
- ##STR4## 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-glucoses having 1,2-, 1,4- and/or 1,6-bond, provided that the total number of the D-glucose residue in R.sub.1 and R.sub.2 is 4 to 6, and a non-toxic carrier and provided that both R.sub.1 and R.sub.2 are not both hydrogen at the same time.
