Abstract
Bioassay-guided fractionation based on the anti-inflammatory activity of a methanol extract of Ficus microcarpa leaves led to the isolation of seven galactolipids: 2(S)-3-O-octadeca-9Z,12Z,15Z-trienoylglyceryl-O-β-D- galactopyranoside (1), (2S)-2,3-O-dioctadeca-9Z,12Z,15Z-trienoylglyceryl-O- β-D-galactopyranoside (2), (2S)-2,3-O-dioctadeca-9Z,12Z-dienoylglyceryl-O- β-D-galactopyranoside (3), (2S)-3-O-octadeca-9Z,12Z,15Z-trienoylglyceryl- 6′-O-(α-D-galactopyranosyl)-β-D-galactopyranoside (4), (2S)-2,3-O-dioctadeca-9Z,12Z,15Z-trienoylglyceryl-6'-O-(α-D- galactopyranosyl)-β-D-galactopyranoside (5), gingerglycolipid B (6), and (2S)-2,3-O-dioctadeca-9Z,12Z-dienoylglyceryl-6′-O-(α-D- galactopyranosyl)-β-D-galactopyranoside (7). Their chemical structures were elucidated by mass, 1D-, and 2D-NMR spectroscopic methods as well as chemical methods. The antiinflammatory effect of these compounds on TNF-α induced IL-8 secretion in the HT-29 cell line was evaluated. All above galactolipids showed significant inhibition ranging 40% at a concentration of 50 μM. The results suggest that galactolipids from the leaves of F. microcarpa may be used as potent anti-inflammatory agents.
