Abstract

Abstract: Cyclovirobuxinum D was isolated from traditional Chinese medicine Buxus icrophylla Sieb. et Zucc, for treating coronary heart disease and arrhythmias. High performance liquid preparation chromatography was used for separation and purification. ¹³C and ¹H chemical shifts of the compound were assigned using 1D and 2D NMR techniques including ¹H NMR, ¹³C NMR, COSY, DEPT, HMQC and HMBC. The structure of the compound was determined from the NMR data.

Key words: NMR, chemical shift, 2D NMR, cyclovirobuxinum D, Buxus alkaloids

CLC Number:

O641
