Isoflavonoid production by callus cultures of Maackia amurensis.
Callus cultures were established from the different parts of Maackia amurensis plants and analyzed for isoflavonoids. The isoflavones daidzein, retuzin, genistein and formononetin and the pterocarpans maakiain and medicarpin were found to be produced by these cultures. The content of isoflavones and pterocarpans was essentially the same in cultures derived from leaf petioles, inflorescences and apical meristems of the plant. The maximal yield of isoflavones and pterocarpans in calluses was 20.8 mg/g cell dry wt., approximately four times higher than the content of the heartwood of M. amurensis plants. Unlike wild-growing plants, none of the cell cultures had the ability to accumulate stilbenes.
