Popis: Morinda citrifolia L. belongs to family Rubiaceae. It is a traditional Polynesian medicinal plant. Its root serves as a rich source of various anthraquinone constituents. The anthraquinone compounds exhibit therapeutic effects of antibacterial, antiviral and anticancer activities. In the present work, an adventitious root culture of M. citrifolia was established and the effectiveness of various elicitors viz, yeast extract, xylan, pectin and the precursor α-ketoglutaric acid on the level of anthraquinone production in adventitious root cultures were assayed. Adventitious root proliferation was achieved in Murashige and Skoog liquid medium supplemented with 24 μM Indole-3-butyric acid. The anthraquinone content was determined by spectrophotometric analysis and the anthraquinone constituents–viz, alizarin and purpurin were quantified by high-performance liquid chromatographic method. Enhancement in alizarin and purpurin along with total anthraquinones was detected due to the addition of precursor and elicitors. Pectin (20 mg/l) added cultures resulted in highest anthraquinone accumulation (44.4 mg/g dw). The protocol developed for the regeneration of roots was simple, reproducible and reliable for the possible commercial production of in vitro root biomass based alizarin and purpurin.
