Popis: | A pair of 2,3-seco cafestol-type diterpenoid epimers, frutilactones A (1) and B (2) were isolated from twigs of Tricalysia fruticosa. Their structures were elucidated by comprehensively employing spectroscopic methods (MS and 1D/2D NMR) and ECD. Their inhibitory effects on nitric oxide production in lipopolysaccharide-activated macrophages were evaluated, and a possible biogenetic pathway was also proposed. |
