  • Title: Isolation and identification of a phenolic antioxidant from Aloe barbadensis.
    Author: Lee KY, Weintraub ST, Yu BP.
    Journal: Free Radic Biol Med; 2000 Jan 15; 28(2):261-5. PubMed ID: 11281293.
    Abstract:
    A potent antioxidative compound has been isolated from a methanolic extract of Aloe barbadensis Miller using a combination of column and thin-layer chromatography. The antioxidant activity of this substance was similar to that of alpha-tocopherol as assessed in vitro using rat brain homogenates. On the basis of electrospray ionization and electron-impact ionization mass spectra in combination with reversed-phase, high-performance liquid chromatographic behavior, this compound has been identified as 8-C-beta-D-[2-O-(E)-coumaroyl]glucopyranosyl-2-[2-hydroxy]-propyl-7-methoxy-5-methylchromone.
