Abstract
The health benefits of dates arise from their content of phytochemicals, known for having pharmacological properties, including flavonoids, carotenoids, phenolic acids, sterols, procyanidins, and anthocyanins. In vitro cell culture technology has become an attractive means for the production of biomass and bioactive compounds. This chapter describes step-by-step procedures for the induction and proliferation of callus from date palm offshoots on Murashige and Skoog (MS) medium supplemented with plant growth regulators. Subsequently cell suspension cultures are established for optimum biomass accumulation, based on the growth curve developed by packed cell volume as well as fresh and dry weights. The highest production of biomass occurs at the 11th week after culturing. Moreover, this chapter describes methodologies for the extraction and analysis of secondary metabolites of date palm cell suspension cultures using high-performance liquid chromatography (HPLC). The optimum level of catechin, caffeic acid, apigenin, and kaempferol from the cell suspension cultures establishes after the 11th and 12th weeks of culture. This protocol is useful for scale-up production of secondary metabolites from date palm cell suspension cultures.
