Flavonoids are by far the most dominant class of phenolic compounds isolated from Morus alba leaves (MAL).Other classes of compounds are benzofurans,phenolic acids,alkaloids,coumarins,chalcones and stilbenes.Major flavonoids are kuwanons,moracinflavans,moragrols and morkotins.Other major compounds include moracins (benzofurans),caffeoylquinic acids (phenolic acids) and morachalcones (chalcones).Research on the anticancer properties of MAL entailed in vitro and in vivo cytotoxicity of extracts or isolated compounds.Flavonoids,benzofurans,chalcones and alkaloids are classes of compounds from MAL that have been found to be cytotoxic towards human cancer cell lines.Further studies on the phytochemistry and anticancer of MAL are suggested.Sources of information were PubMed,PubMed Central,ScienceDirect,Google,Google Scholar,J-Stage,PubChem and China National Knowledge Infrastructure.
