半夏姜制对鸟苷含量的影响

Effect of Ginger processing on Contents of Guanosine in Pinelliae Rhizoma(Banxia)

目的：比较“正交法”和药典法两种炮制工艺的姜半夏中微量水溶性成分鸟苷的含量，对半夏的其他姜制炮制品中鸟苷含量进行比较。方法：采用反相高效液相色谱法。结果：“正交法”和药典法两种炮制工艺炮制的姜半夏中鸟苷含量接近，与生半夏相比，没有明显变化，其他炮制品的鸟苷含量则有较大幅度下降。结论：“正交法”和药典法炮制的姜半夏没有明显区别。

Objective:To compare the guanosine contents in various products of Pinellia Rhizoma processed by different amounts of ginger and alum.Method:Using the technology of HPLC.Result:The guanosine contents in the two pro ducts of Pinellia Rhizoma processed in line with the pharmacopoeial method and orthogonal method respectively are very close to each other and changevery little as compared with raw Pinellia Rhizoma.But the contents in the products of Pinelliae Rhizoma processed in other ways (digged in alum solution or in ginger Juice decocted with ginger juice,etc.) are much less than those of raw Pinellia Rhizoma.Conclusion:There are no obvious differences in guanosine contents between Pinellia Rhizoma processed by orthogonal technology and Pinellia Rhizoma processed by pharmacopoeial method.Processing technology has considerable influence on the water soluble components of Pinellia Phizoma.
