Abstract 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.
