Garcimultiflorone G, a novel benzoylphloroglucinol derivative from Garcinia multiflora
Garcinia multiflora (Guttiferae) Champ. is a small evergreen tree, distributed in South China, Hong Kong, and Taiwan. Xanthones, biflavonoids, benzophenones, phloroglucinol, and their derivatives are widely distributed in plants of genus Garcinia. Many of these compounds exhibit anti-inflammatory, anti-HIV, antitubercular, cytotoxic, and antioxidant activities. In our studies on the anti-inflammatory constituents of Formosan plants, many species have been screened for in vitro anti-inflammatory activity, and G. multiflora has been found to be an active species. In our search for compounds with anti-inflammatory activities, an additonal new benzophenone derivative, garcimultiflorone G (1) has been isolated and identified from the fruits of G. multiflora. The structural elucidation of garcimultiflorone G (1) was established by spectroscopic and MS analyses and its anti-inflammatory activity was evaluated by suppressing fMet-Leu-Phe/cytochalasin B (fMLP/CB)-induced superoxide anion (O2 ·-) generation and elastase release by human neutrophils.
