Abstract
An assay is described for the estimation of total anthracene derivatives in senna, rhubarb or their preparations. The extracted glycosides are oxidised by ferric chloride in aqueous solution followed by hydrolysis in acid solution. The free anthraquinones are estimated colorimetrically.Keywords
