| Section2 = }} Morindone is an anthraquinone compound obtained from various ''Morinda'' species, especially ''M. tinctoria'', but also ''M. citrifolia''. Its principal use is as a dye, but it has also been investigated for anticancer and microbial uses. == Preparation == Morindone is obtained from the root bark of ''M. tinctoria'' or related species in two stages. In the first step, small roots of immature plants are boiled in alcohol to obtain morindin, a yellowish substance which can also be used in dyeing. Further heating brings about hydrolysis of two glucose monomers through sublimation, leaving intensely red crystals. ''M. tinctoria'' is extensively grown in India for commercial production. Moridin content in the roots peaks in two to three years and drops off considerably after that; some attempts have been made to speed up production using tissue cultures. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「morindone」の詳細全文を読む スポンサード リンク
