It is well known that plants are the source of valuable products and some useful basic materials including cellulose, wood, and rubber. In addition, secondary metabolites such as terpenoids, cardenolides, coumarins, anthraquinones, flavonoids, glucosinolates and alkaloids are also produced by plants and are used as drugs flavors, pigments (food ingredients), and agrochemicals. Hitherto some secondary metabolites have been produced using the plant cultured cells. Furthermore, many studies have recently focused on the ability of the plant cultured cells to transform foreign substrate (biotransformation). In this study, to clarity the conversion ability of plant cultured cells, the biotransformation of bioactive compounds such as hesperetin and vitamin E derivatives (dl-α-tocopherol, TMC-10, pentamechyl-6-chromanol and trolox), using the plant cultured cells of Eucalyptus perriniana was carried out Furthermore, the biotransformation of pentamechyl-6-chromanol using the plant cultured cells of Catharanthus roseus and Phytolacca americana was executed. From this experiment result, it was found that the cultured cells of E. perriniana predominantly glycosylated hesperetin, pentamethyl-6-chromanol, and trolox. In addition, the plant cultured cells of C. roseus and P. americana glycosylated the hydroxyl group of pentamethyl-6-chromanol.
