Anti-inflammatory monoterpene esters from the stems of Illigera aromatica

Abstract

Two new monoterpene esters illigerates F and G (1 and 2) together with 5 know compounds illigerate A (3), illigerate C (4), actinodaphnine (5), N-methylactinodaphnine(6) and N-methyllaurotetanine(7) were isolated from Illigera aromatica S. Z. Huang et S. L.Mo. Their structures were identified by extensive NMR data and by comparing with the known compounds. The anti-inflammatory activity of four monoterpenes (1 -4) was evaluated by inhibiting nitric oxide (NO) production in lipopolysaccharide-activated
