ABSTRACT
OBJECTIVE:
To study the phenolic glycosides of Urena lobata.METHODS:
Compounds were isolated and purified using various column chromatographies such as D101 macroporous adsorption resin, silica gel, Sephadex LH-20, and preparation HPLC. Their structures were established using extensive spectroscopic techniques such as MS and NMR. The anti-inflammatory activities of all compounds were evaluated by using LPS-stimulated RAW264.7 cells.RESULTS:
Twelve phenolic glycosides were obtained from the n-BuOH extract of U. lobata including benzyl-7-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (1), phenylethyl-8-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (2), phenylethyl-8-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (3), eugenyl-1-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (4), 6-methoxyeugenyl-1-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (5), 3,4,5-trimethoxybenzene-1-O-α-L-rhamnosyl-(1→6)-β-D-glucopyranoside (6), 4-O-(glycer-2-yl)-dihydroconiferylalcohol-1′-O-β-D-mannopyranoside (7), benzyl-7-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside (8), 3,5-dimethoxy-4-hydroxyphenylethyl-8-O-β-D-glucopyranoside (9), 3,4,5-trimethoxybenzene-1-O-β-D-glucopyranoside (10), phenylethyl-8-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside(11),and 3,4,5-trimethoxybenzene-1-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (12).CONCLUSION:
Compounds 2-8 and 10-12 are obtained from the family Malvaceae for the first time, and compounds 3, 8, 9 and 11 show moderate inhibition of nitric oxide production in LPS-stimulated RAW264.7 cells, with IC50values of(40.5±4.9 ), (31.9±4.6),( 37.7±3.3 ), and (36.1±4.6 )μmol•L-1, respectively.
