Abstract:
Three new compounds, including two new diterpenoids, named epianhydrocinnzeylanol (1) and cinnacasiol H (2), and one hydroxylasiodiplodin, (3R,4S,6R)-4,6-dihydroxy-de-O-methyllasiodiplodin (3), together with five known diterpenoids (4-8) and two known phenolic glycosides (9-10) were isolated from the barks of Cinnamomum cassia. Their structures were elucidated by extensive spectroscopic analysis and comparison of the chemical shift values with those of related known compounds. The anti-inflammatory activities of the isolates were evaluated on nitric oxide production in lipopolysaccharide-induced BV-2 microglial cells and the compounds showed weak inhibition activities.
