生物磁效应对蛹虫草活性物质含量的影响

Effects of Biomagnetic Effect on the Bioactive Metabolite Production in Fruiting Body of Cordyceps militaris

利用场强为0.1、0.25、0.4T恒定磁场,以流速为1 m·s^(-1),分别对普通水进行9次处理,串联(SC)磁场处理3次的磁处理水,进而用于栽培蛹虫草,并研究了生物磁效应对蛹虫草虫草素、虫草酸、多糖含量及生物学转化效率的影响。结果表明,0.4T处理有利于蛹虫草虫草酸含量及生物学效率的提高,相比对照组分别提高了7.29%和15.37%;0.25T处理组有利于虫草素的积累,比对照组提高了11.31%;0.1T处理有利于多糖的积累,相比对照组提高了14.80%。方差分析表明,经不同场强处理的磁化水对蛹虫草子实体生长和活性物的代谢影响差异显著。但磁处理水对于不同物质含量的影响规律存在一定的差异性。

We carried magnetic treatment for 9 times on ordinary water with field strength of O. 1, O. 25, O. 4T, while treating the series connection （ SC ） 3 times, in flow velocity for 1.0 m s - i and the distance of 30 cm, respectively to culture. Furthermore, the influence of different magnetic field strength on biological efficiency, cordycepin, cordycepic acid （D-mannitot）, polysaccharide by the fruiting body of Cordyceps militaris were investigated. Under the same condition, the 0. gT treatment was favorable for and cordycepic acid production and fruiting body growth,which increased 7.29 % and 15.37% compared with the contrast ,respectively. The 0.25T treatment was favorable for cordycepin production of C. militaris, which increased 11.31% compared with the contrast. The 0.1T treatment was favorable for polysaccharide production in the fruiting body of C. militaris, which increased 14. 80% compared with the contrast. ANOVA showed that different magnetized water had significant effect on fruiting body growth and active substance production. Besides, the influence rules of magnetized water on different substance existed differences.
