Four intensely sweet compounds (I apprx IV) were obtained from the leaves of Cyclocarya paliurus. 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.
