Antioxidant, icthyotoxicity and brine shrimp lethality tests of Magonia glabrata

The ethanolic extract of the fruit bark from Magonia glabrata yielded shikimic acid, scopoletin, sitosterol glycoside and 2-O-methyl-L-inositol. Antioxidant, icthyotoxicity and brine shrimp lethality activities were observed in this extract. The major constituent, 2-O-methyl-L-inositol, was found to be inactive in two assays but showed moderate activity as a radical scavenger. (c) 2006 Elsevier B.V. All rights reserved.
