目的比较几种生物诱导子〔酵母提取物(yeast ex tract)、寡半乳糖醛酸(o ligoga lacturon ides)、真菌诱导子(funga l e lic itor)〕和非生物诱导子(A g+、Co2+和α-氨基异丁酸)对丹参毛状根培养生产丹参酮的影响。方法高效液相色谱法测...目的比较几种生物诱导子〔酵母提取物(yeast ex tract)、寡半乳糖醛酸(o ligoga lacturon ides)、真菌诱导子(funga l e lic itor)〕和非生物诱导子(A g+、Co2+和α-氨基异丁酸)对丹参毛状根培养生产丹参酮的影响。方法高效液相色谱法测定3种丹参酮。结果生物诱导子一般都能有效地提高丹参酮的产量,不同诱导子的诱导效果之间存在差别。最高的丹参酮产量由100μg/mL的真菌诱导子获得,是对照组产量(0.42 m g/g)的4.7倍。非生物诱导子对丹参酮的诱导能力相对生物诱导子较差,其中50μm o l/L Co2+获得了最高的丹参酮产量(1.75 m g/g),是对照组产量的4.1倍。生物诱导子和非生物诱导子表现出了一定的诱导选择性。所有的生物诱导子都显著提高了隐丹参酮的量而所有的非生物诱导子都选择性地提高了丹参酮Ⅰ的量。并且在大部分情况下,添加的诱导子都没有对丹参毛状根的生长造成明显的抑制作用。结论在丹参毛状根培养中添加不同的生物和非生物诱导子都可以选择性地提高丹参酮的积累,并且不影响毛状根的生长。展开更多
