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
Four undescribed 23,24-O-isopropylidene-19(18 → 17)-abeo-28-noroleanane-derived spirocyclic triterpenoids and an undescribed 28-noroleanane-derived spirocyclic triterpenoid, together with five known 28-noroleanane-derived spirocyclic triterpenoids, were isolated and identified. In addition, three
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
