Transilin is a sesquiterpene lactone. Transilin can be isolated from the whole plant of Lepisorus contortus (Christ) Ching[1].

ChEBI: 3-O-methylquercetin-7-O-beta-D-glucopyranoside is a quercetin O-glucoside that is 3-O-methylquercetin attached to a beta-D-glucopyranosyl residue at position 7 via a glycosidic linkage. It has been isolated from Ophioglossum pedunculosum and Lepisorus contortus. It has a role as a metabolite and a plant metabolite. It is a quercetin O-glucoside, a beta-D-glucoside and a monosaccharide derivative.
