ABSTRACT
This study aimed to investigate the anti-allergic activity of compounds isolated from Geranium wilfordii Maxim. and to suggest potential therapeutic agents for allergies. Nine compounds were isolated from an ethanolic G. wilfordii extract using chromatographic methods and identified chemically and by spectroscopic analysis. These compounds were identified using reported literature data as brevifolin carboxylic acid (1), chlorogenic acid (2), corilagin (3), ellagic acid (4), geraniol (5), kaempferol 3-O-dirhamnoside (6), kaempferol 3-O-neohesperidoside (7), protocatechuic acid (8), and gallic acid (9). All nine identified compounds were assessed for including IL-4 mRNA expression and ß-hexosaminidase release in RBL-2H3 cells stimulated with PMA/ionomycin or IgE + DNP-BSA. IL-4 gene expression assay showed that corilagin (3) potently inhibited IL-4 production, and ß-hexosaminidase release assay showed that protocatechuic acid (8) markedly reduced histamine release. The study shows that of the nine compounds isolated from G. wilfordii, corilagin (3), and protocatechuic acid (8) are potential treatments for allergy-related diseases.
