Glycosides are the bioactive components of many famous Chinese medicines. Here reported are some bioactive glycosides we discovered from Chinese medicines in recent years. (1) Phenolic glycosides from Chinese medicines: Gastrodia elata, Aconitum austroyunanense and Helicia erratica, three bioactive
A new iridoid ester glycoside acylated with p-coumaric acid was isolated from the flowers of Verbascum phlomoides, together with one known one, specioside. Caffeic acid esters, verbascoside and forsythoside B were found as minor constituents. A new saponin was also obtained and identified as
Chemical investigation on the root of Phlomoides betonicoides led to the isolation of six undescribed diterpenoid glycosides, phlomoidesides A-F, along with two known ones using various chromatographic techniques. The structures of these compounds were determined by extensive spectroscopic analyses
