The production in Hyoscyamus hairy roots was reported to be stable during at least 10 subcultures (337). Hairy root cultures of Scopolia japonic a were selected for high alkaloid production. Media were optimized for growth and alkaloid production. One cell line, SI, produced scopolamine as the major alkaloid (0.5% of DW) the productivity was approximately 17 mg/liter in 4 weeks. Cell line S22 had atropine as the major alkaloid (1.3% of DW), from which a productivity of about 117 mg/liter in 4 weeks can be calculated (347,348). A similar productivity for atropine was found in Datura stramonium hairy roots (50-100 mg/liter in 4 weeks) (314,317). The Datura roots excreted about 5% of the atropine into the medium in the stationary phase this increases to about 30% with a concomitant decrease in total alkaloids (317). Datura wrightii was found to produce about 180 mg/liter of atropine, a production which was reached after only 15 days, which is considerably faster than the 45 days after which maximum alkaloid production is achieved in D. stramonium (317).

Solandra (4), Brugmansia (3), Datura (5), Physalis (1)]. Surprisingly, 3P-acetoxytropane was identified only in a few species of the Solanoideae (H. albus, H. pusiUus, B. Candida x aurea, D. wrightii, P. peruviana). Finally, 3p-(2-methylbutyryloxy)tropane seems to be confined to D. inoxia (Witte et al. 1987).
