    摘要: The fresh seeds obtained from the fresh fruits of Garcinia subelliptica, were extracted with chloroform at room temperature. The CHCl3 extract was concentrated under reduced pressure to afford a brown residue. This residue was subjected to column chromatography (silica gel) and eluted with appropriate solvent system to give two phloroglucinol derivatives (Compounds 1 and 4). Compound 1 exhibited potent inhibitory effects on the release of β-glucuronidase and lysozyme from rat neutrophils stimulated with formyl-Met-Leu-Phe(fMLP)/cyto-chalasin B (CB). Compound 1 also exhibited potent inhibitory effect on the superoxide anion generation in rat neutrophils stimulated with fMLP/CB. Compound 4 exhibited potent inhibitory effect on NO production in lipopolysaccharide (LPS)/interferon-γ (IFN-γ)-activation in N9 cells. These Compounds may be developed as anti-inflammatory, anti-cancer agent, cure for ageing, and Alzheimer's disease treatment drugs.
