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 twodimensional NMR spectroscopic data. © 2013 The Pharmaceutical Society of Japan.
