Abstract
Two new sesquiterpenes, litseachrandaevanes C and D (1 and 2), together with five known sesquiterpenes (3 − 7), were isolated from the stems of Fissistigma glaucescens (Hance) Merr. Their structures were elucidated using comprehensive spectroscopic methods. The inhibitory effect of all compounds on the proliferation of primary synovial cells was evaluated. Compound 3 showed inhibitory effect on the proliferation of synoviocytes, with an IC50 value of 12.5 μM.
