Schoepfiajasmins A–H: C-Glycosyl Dihydrochalcones, Dihydrochalcone Glycoside, C-Glucosyl Flavanones, Flavanone Glycoside and Flavone Glycoside from the Branches of Schoepfia jasminodora

Abstract

From the branches of Schoepfia jasminodora collected in Okinawa, three new dihydrochalcone C-glycosides, one dihydrochalcone di-O-glucopyranoside, two flavanone C-glycosides, one flavanone O-glycoside and one flavone O-glycoside were isolated. Their structures were elucidated by extensive study of one- and two-dimensional NMR spectroscopic data.
