Charactbristics of Scopolamine-releasing Hairy Root Clones of Duboisia leichhardtii

Abstract

A good scopolamine-releasing hairy root clone, DL47-1, was developed from Duboisia leichhardtii. Hyoscyamine 6β-hydroxylase activity of the clone DL47-1 in the medium for alkaloid release was 2-fold higher than that in the medium for hairy root growth. Other high scopolamine-producing clones also tended to have a high enzyme activity.
