Bioassay-Guided Fractionation of Acetone and Methanol Extracts of Quercus infectoria Galls with Antimalarial Properties.
The antimalarial properties of crude extracts from Quercus infectoria galls were investigated through bioassay-guided fractionation. Acetone (QIA) and methanol (QIM) crude extracts have been reported to have promising antimalarial activity against Plasmodium falciparum (3D7 strain). These extracts were subjected to fractionation using automated preparative high-performance liquid chromatography (prep-HPLC) to identify the most active fractions. Nine fractions were isolated from each extract, of which the fractions QIA11 and QIM16 showed antimalarial activity, with IC50 values of 17.65 ± 1.82 μg/mL and 24.21 ± 1.88 μg/mL, respectively. In comparison, the standard antimalarial drug artemisinin has an IC50 value of 0.004 ± 0.001 μg/mL). Through high-resolution liquid chromatography coupled with mass spectrometry (HR-LCMS) analysis of the fractions, four known compounds were successfully identified: gallic acid, ellagic acid, 1,3,6-tris-o-(3,4,5-trihydroxybenzoyl)-beta-d-glucose and 1-O,6-O-digalloyl-beta-D-glucose.
期刊介绍：
Tropical Life Sciences Research (TLSR) formerly known as Journal of Bioscience seeks to publish relevant ideas and knowledge addressing vital life sciences issues in the tropical region. The Journal’s scope is interdisciplinary in nature and covers any aspects related to issues on life sciences especially from the field of biochemistry, microbiology, biotechnology and animal, plant, environmental, biomedical and pharmaceutical sciences. TLSR practices double blind peer review system to ensure and maintain the good quality of articles published in this journal. Two issues are published annually in printed and electronic form. TLSR also accepts review articles, experimental papers and short communications. The Chief Editor would like to invite researchers to use this journal as a mean to rapidly promote their research findings.
