    摘要: The present invention relates to a method for the preparation of a melanic pigment by enzymatic bioconversion, implementing a melanin precursor substrate and plant cells, characterized in that: (a) poppy (Papaver somniferum) plant cells previously cultivated are separated from their culture medium and subcultured in a culture medium with a concentration from 10 to 100 g/l; (b) the cells are ground at least partially, before or at the end of the latency time, (c) the at least partially ground cells are placed in a bioconversion medium in the presence with a melanin precursor substrate selected amoung indol, indolin, dihydroxyphenylalanin, tyramin and tyrosin; (d) the precipitated melanic pigment is collected. The invention also relates to the utilization of such resulting pigments for the preparation of cosmetic compositions.
