Abstract

Two new sesquiterpene esters, celaglaupin and celaglausin, have been isolated from the root bark of Celastrus glaucophyllus. Their structures have been elucidated on the basis of two-dimensional NMR ¹H-¹H COSY, ¹³C-¹H COSY, and NOESY) and other spectral (UV, IR, HR-mass, and DEPT) analysis as well as chemical methods, respectively.

Key words

Celastrus glaucophyllus - celaglaupin - celaglausin - sesquiterpene esters - structural elucidation
