<p>A process for producing oleanolic acid analogs which comprises inducing and culturing hairy roots originating in a plant capable of forming oleanolic acid analogs (such as myricerol, 27-hydroxy-caffeoylmyricerol, myricerone or 27-hydroxy-caffeoylmyriceron) by using plasmids such as Ri plasmid capable of inducing hairy roots and taking up the oleanolic acid analogs from the culture medium thus obtained.</p> |
