Analysis of Phenolics in Calligonum polygonoides In Vitro Cultured Roots

Abstract

Background: Calligonum polygonoides L. subsp. Comosum (L’Hér.) Sosk. is an endangered plant species belonging to family Polygonaceae. Although the plant is rich in phytoconstituents and has multipurpose medicinal applications, but in vitro root culture studies and phytochemical investigations of these cultures are rare. Objectives: To establish in vitro root, callus and cell suspension cultures from in vitro germinated fruits of C. polygonoides to investigate the production of phenolics through root, callus and cell suspension cultures and attempt to enhance cell capacity to accumulate phenolics. Materials and Methods: Modified Murashige and Skoog medium supplemented with 1 mg l-1 indole-3-butyric acid was used to establish the root culture. Elicitation of cell suspension culture was performed using salicylic acid and yeast extract. The phenolic compounds in root, callus and cell suspension cultures were evaluated using reversed phase high performance liquid chromatography technique.
