3-O-methylgalangin is a naturally-occurring flavonoid. It is isolated and purified from the rhizomes of Alpinia officinarum and flowers of Helichrysum kraussii and H. odoratissimum. 3-O-methylgalangin exhibited significant anti-platelet aggregation activity in vitro. It has antioxidant activity. The higher antioxidant activity 3-O-methylgalangin can be attributed to the presence of C-2-C-3 unsaturation allowing the resonance stabilization of the formed radical. Flavonoids are known for their antimicrobial properties and 3-O-methylgalangin possess antibacterial activity against Gram-positive and Gram-negative bacteria also. 3-O-methylgalangin is an inhibitor of pancreatic lipase and it was reported that it lowered serum triglyceride level on corn oil-induced hyperlipidemic mice.

In Vitro Use Guide

To determine the effect of 3-O-methylgalangin on the growth curve of E. coli and B. subtilis, it was added to exponentially-growing cultures. 3-O-methylgalangin decreased the culture turbidity and cell viability of the Gram-positive bacteria Bacillus subtilis with the concentration 0.01 ug/ul. 3-O-methylgalangin showed a MICs that ranged from 0.25 to 1 ug/ml for tested Gram-negative bacteria (Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis) and Gram-positive bacteria (Bacillus cereus, B. subtilis, B. coagulans, and Staphylococcus aureus).
