Alkannin, a red-purple dye and bioactive compound found in the roots of Arnebia hispidissima has antibiotic and anti-inflammatory properties and is also used in cosmetic and textile industries at a large-scale. In the present communication, we demonstrate the establishment of callus and cell suspension culture of A. hispidissima with the aim of optimizing the production of alkannin. Highest alkannin content was recorded in cell suspension and callus culture established on M-9 medium. Production of alkannin was influenced by the different culture medium. Evaluation of alkannin content of roots of field-grown plants and in vitro grown cell, tissue and organ showed that alkannin production was higher in all in vitro grown culture systems (cell suspension, callus and roots) than the roots of fieldgrown plants. The present investigation may be applicable in designing systems for the large-scale cultivation of A. hispidissima cell suspensions for the production of alkannin.
