Task: Please create a text description for a molecule.
Molecule SMILES: Oc1cc(O)cc(Oc2c(O)cc(O)c3c2Oc2c(O)cc(O)cc2O3)c1
Constraint: Answer the question with full sentences.
Result: The molecule is a phlorotannin that is oxanthrene-1,3,6,8-tetrol substituted by a 3,5-dihydroxyphenoxy moiety at position 4. Isolated from the marine brown alga, Ecklonia cava, it exhibits antioxidant activity. It has a role as a metabolite and an antioxidant. It derives from a phloroglucinol.
