A new cembrane glycoside in Asterothamnus centrali-asiaticus from Gobi desert

Abstract

A new cembrane glycoside, nephthenol 15-O-β-d-quinovoside, was isolated from the aerial parts of Asterothamnus centrali-asiaticus. Its structure was elucidated by 1D and 2D NMR spectroscopic analysis, as well as by mass spectrometry. This is the first report of the occurrence of a cembrane glycoside in vascular plants.
