Sesquiterpenes from with anti-neuroinflammatory effects.

An anti-neuroinflammatory activities-guided phytochemical research of was performed for the first time. Three undescribed carotane-type sesquiterpenes, excoecafolinols C-E (), and nine known sesquiterpene derivatives were isolated from the effective ethyl acetate extract of . Their structures were determined based on multiple spectroscopic techniques and electronic circular dichroism (ECD) spectra.
