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.
从冲绳收集的茉莉schoepfia jasminodora的分支中,分离出三种新的二氢查耳酮C-糖苷,一种二氢查耳酮二-O-葡萄糖吡喃糖苷,两种黄烷酮C-糖苷,一种黄烷酮O-糖苷和一种黄酮O-糖苷。一维和二维NMR光谱数据的广泛研究阐明了它们的结构。
