- Abstract
- Phytochemical investigation of the roots of Echinops latifolius led to the isolation of a new carbon skeleton dimeric sesquiterpene (1) and a new thiophene (2), along with six known compounds (3-8). Their structures and relative stereochemistry were elucidated by spectroscopic and spectrometric methods (H-1 and C-13 NMR, COSY, HSQC, HMBC, ROESY, and MS). All isolates were evaluated for their inhibition of LPS-induced NO production in RAW 264.7 cells. Compounds 4 and 5 exhibited the most potent inhibitory effects on NO production.
