摘要:

通过在北柴胡不定根系培养体系中添加目的产物柴胡皂苷的前体物质和生物合成促进物质以及进行高糖渗透胁迫试验,探讨了利用不定根系生产柴胡皂苷的条件和方法。结果表明,在1/2 MS培养基中添加硫酸镁、硝酸钾、丙酮酸钠以及高糖渗透胁迫均有利于柴胡皂苷的合成。1/2 MS培养基 + 硫酸镁0.37 g/L + 硝酸钾5.7 g/L + 丙酮酸钠2.0 mmol/L + 蔗糖50 g/L是最适合柴胡皂苷转化合成的培养基,此条件下使柴胡皂苷的含量提高了9.74倍。

Abstract:

The conditions and methods of using Bupleurum chinese adventitious root system to produce saikosaponins were studied through adding precursors,accelerators and high sucrose concentrations. The results showed that the addition of proper concentrations of magnesium sulfate,potassium nitrate,sodium pyruvate and sucrose in medium had the effects on biotransformation and biosynthesis of saikosaponins. The most suitable components were 1/2 MS medium adding 0.37 g/L magnesium sulfate,5.7 g/L potassium nitrate,2.0 mmol/L sodium pyruvate and 50 g/L sucrose,in which the saikosaponins were enhanced 9.74 times.

Key words: Bupleurum chinese DC, adventitious root, biotransformation, saikosaponins
