Five new anthraquinone glycosides, hedanthrosides A–E (1–5, resp.) and two new iridoid glycosides, hediridosides A and B (6 and 7, resp.), along with two known anthraquinones and four known iridoids, were isolated from the stems of Hedyotis hedyotidea (DC.) Merr. The structures of the new compounds were elucidated on the basis of 1D‐ and 2D‐NMR, and HR‐MS analysis and chemical methods.
五个新的蒽醌苷,hedanthrosides A-E(1 - 5,RESP)和两个新的环烯醚萜苷,hediridosides A和B(6和7。,RESP),用两个已知的蒽醌和四个已知环烯醚萜一起,被从分离Hedyotis hedyotidea(DC。)Merr的茎。在1D和2D-NMR以及HR-MS分析和化学方法的基础上阐明了新化合物的结构。
