title: [Studies on the sweet principles from the leaves of Cyclocarya paliurus (Batal.) Iljinskaya].
abstract: Four intensely sweet compounds (I-IV) were obtained from the leaves of Cyclocarya paliurus (Batal.) Iljinskaya. The structure of compound I was elucidated by chemical and spectroscopic methods as 20,24-epoxy-dammarane-(3 beta,12 beta,24R)-12-O-alpha-L-rhamnopyranosyl-25- hydroxyl-3-O-alpha-(5'-O-acetyl)-L-arabinofuranoside. It is a new natural product, named cyclocarioside A, and is the main sweet principle of this plant, possessing about 200 times the sweetness intensity of sugar.
