文摘Six new diterpene-quinones were isolated from the ethanol extract of the roots of Tripterygium regelii Sprague and their structures were elucidated through interpretation of their spectroscopic data and chemical correlations. The absolute configuration of triptoquinonoic acid A (1) was determined by X-ray crystallography.
