【 摘 要 】

The roots from Operculina macrocarpa (L.) Urb., Convolvulaceae, are widely used in Brazilian traditional medicine as a laxative and purgative. The biological properties of this drug material have been attributed to its polysaccharides content. Thus, the aim of this study was to evaluate the polysaccharide content in drug material from O. macrocarpa by spectrophotometric quantitative analysis. The root was used as plant material and the botanical identification was performed by macro and microscopic analysis. The plant material was used to validate the spectrophotometric procedures at 490 nm for the quantification of the reaction product from drug polysaccharides and phenol-sulfuric acid solution. The analytical procedure was evaluated in order to comply with the necessary legal requirements by the determination of the following parameters: specificity, linearity, selectivity, precision, accuracy and robustness. This study provides with a simple and valid analytical procedure (linear, precise, accurate and reproducible), which can be satisfactorily used for quality control and standardization of herbal drug from O. macrocarpa.
