Background:

7-O-Methylaloeresin A is 5-methylchromone glycoside isolated from Commiphora socotrana (Burseraceae)[1]. 7-O-Methylaloeresin A exhibits good activity against multiple drug resistant Staphylococcus aureus (NCTC 11994) and Salmonella typhimurium (ATCC 1255) with MIC values of 0.72 and 0.18 mM, respectively[2].7-O-Methylaloeresin A has antioxidant activities, gives IC50 values of 0.026 mM and 0.021 mM for DPPH and 2-deoxyribose degradation assay, respectively[2].
