It has been isolated from several plant species and exhibits antioxidant and anti-allergic properties. It has a role as a plant metabolite, an antioxidant and an anti-allergic agent. It is a methyl ester, a member of pyrans, an enoate ester, a beta-D-glucoside, a monosaccharide derivative, a dicarboxylic acid monoester and a secoiridoid glycoside. It is a conjugate acid of a secoxyloganin(1-)."}]
