It is isolated from the leaves of Alvaradoa haitiensis and exhibits cytotoxicity against human oral epidermoid carcinoma. It has a role as a metabolite and an antineoplastic agent. It is a C-glycosyl compound, an acetate ester, a member of anthracenes and a polyphenol. It is functionally related to a 3-methylbut-2-enoic acid."}]
