H. Mizutani et al., ANTHRAQUINONE PRODUCTION BY CELL-SUSPENSION CULTURES OF RUBIA AKANE NAKAI, Bioscience, biotechnology, and biochemistry, 61(10), 1997, pp. 1743-1744
The effects of various plant growth regulators and nutrients on cell g
rowth and anthraquinone production in cell suspension cultures of Rubi
a akane NAKAI were investigated. Use of an optimized medium resulted i
n a two-fold increase in the anthraquinone content. From the cell cult
ures 1,2-dihydroxyanthraquinone was isolated as the main constituent.
