| 产品描述 | 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 |
| 体外活性 | 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] |
