3,3'-Di-O-methylellagic acid reveals moderate antibacterial activity, it also shows strong DPPH radical scavenging activities with SC50 of 123.3 ug/mL. It has a lower capacity of stimulating murine peritoneal macrophages to release nitric oxide and tumoural-alpha necrose factor

The methanolic extract from the barks of the medicinal plant Qualea parviflora (Vochysiaceae) was fractionated by column chromatography over silica gel followed by gel permeation over Sephadex LH-20 to give 3,3'-di-O-methylellagic acid-4-O-beta-D-glucopyranoside (1), 3-O-methylellagic acid-4'-O-alpha-L-rhamnopyranoside (2), 3,3',4-tri-O-methylellagic acid-4'-O-beta-D-glucopyranoside (3), and 3,3'-di-O-methylellagic acid (3,8-Di-O-methylellagic acid,4), together with triterpenes and saponins. We also performed comparative analyses among this species and Q. grandiflora and Q. multiflora using high-pressure liquid chromatography[1]
