Abstract: When the suspension cultures of Anisodus acutangulus were sup-plemented with precursors of either phenylalanine, ornithine or hyocyamine, phenylalanine was found to be most effective in promoting both the cell growth and its conversion to scopolamine. The growth rate of the cultures adding phenylalanine as precursor was 50.2% higher than that without phenylalanine and the ratio of conyersion was 4.0%.

摘要： 在三分三悬浮培养中分别补充前体苯丙氨酸、鸟氨酸和莨菪碱时，悬浮细胞的生长速率及东莨度若碱的转化率均以补充苯丙氨酸者为最高，分别比未加前体的对照增加50.2％和4.0％。
