A new method for the determination of baicalin with HPLC-CL was developed. The method was based on the chemiluminescence reaction between KMnO4 and baicalin sensitized from HCHO. The linear range was 3.7?0-6~9.8?0-5 mol/L with detection limit of 1.7?0-6 mol/L and the relative standard deviation was 2.5 % (Cs=6.6?0-5 mol/L, n=5). The method has been applied to the determination of baicalin in oral administration, injection, Scutellariae radix and granules with good results.

摘 要声乐艺术是音乐范畴中直接运用语言和音乐结合起来、表达思想感情塑造艺术形象的艺术形式。而且声乐是一个非常抽象的学科,在这个过程中经常会遇到各种各样的问题。本文就是通过笔者大学四年在声乐学习过程中遇到的种种问题,论述了在高师声乐专业学习中的练声、咬字吐字等声乐基本功练习内容与方法,以及学习心态等方面的内容。 【关键词】基本功;咬字吐字;歌唱心态 声乐是一个非常抽象的学科,它的学习过程非常艰难
