title: Hepatoprotective sesquiterpene glycosides from Sarcandra glabra.
abstract: Six new sesquiterpene glycosides, compounds 1-6, with eudesmanolide, elemanolide, lindenane, and germacranolide sesquiterpene aglycons, along with one known compound, chloranoside A (7), have been isolated from the whole plant of Sarcandra glabra. The structures of 1-6 were elucidated by chemical and spectroscopic methods including (1)H-(1)H COSY, HMQC, HMBC, and NOESY NMR experiments. In addition, compounds 1-7 showed pronounced hepatoprotective activities against D-galactosamine-induced toxicity in WB-F344 rat hepatic epithelial stem-like cells.
