Abstract

Regelidine (1), a new nicotinoyl sesquiterpene alkaloid, was isolated from the roots of Tripterygium regelii. The structure of 1 was determined on the basis of ¹H-, ¹³C-NMR spectrometry and X-ray crystallography. The absolute configuration of 1 was deduced unambiguously by the anomalous dispersion method.
