High accumulation of dehydrodiconiferyl alcohol-4-beta-D: -glucoside in free and immobilized Linum usitatissimum cell cultures.

As flaxseed mainly accumulates lignans (secoisolariciresinol diglucoside and matairesinol), these compounds were barely or not detected in plant cell suspensions initiated from Linum usitatissimum. In contrast, these cell suspensions were shown to accumulate substantial amounts of a neolignan identified as dehydrodiconiferyl alcohol-4-beta-D: -glucoside (DCG) (up to 47.7 mg g(-1) DW). The formation of this pharmacologically active compound was evaluated as a function of cell growth and in relation to phytohormone balance of the culture media. After establishment of efficient culture conditions, production of DCG was investigated in immobilized plant cell suspensions initiated from plantlet roots of L. usitatissimum. The results indicate that immobilization enhances the DCG production up to 60.0 mg g(-1) DW but depresses the cell growth resulting in no improvement of the total DCG yield. Nevertheless, with immobilized cell suspensions, a release of DCG into the medium is observed allowing an easier recovery.[1]
