51楼楼主，您好。据目前个人能力有限，而且本人也查了很多相关资料，证明用分光光度计检测，的确有些局限性。欢迎楼主能帮我解开这个疑团，同时也希望广大板油们积极来谈论这个问题，

但是，用分光光度计来进行本课题研究，的确有些地方很方便。
根据辩证法原理，一事都有两面性，所以我们搞研究也必须遵照事物的基本规律，辩证地分析。

好详细的文章，非常不错！以前我做过藿香正气水中乙醇含量测定，楼主的文章有亲切感。

谢谢楼主的夸奖。

摘要
双黄连口服液由金银花、黄芩、连翘精制而成。它是传统的中药。本文主要从制备工艺、质量检查等方面进行研究。通过正交试验优选出双黄连口服液最佳的提取工艺，再通过单因素试验考察纯化工艺，并对矫味剂进行考察、筛选，从而为大生产提供合理可行的技术参数。通过薄层色谱鉴别口服液制剂中金银花、黄芩等药味的存在，并且金银花、黄芩分别以绿原酸、黄芩苷为考察指标，并采用HPLC、UV-2000测定金银花、黄芩进行含量测定，规定其下限作为制剂的质量控制指标，以保证临床用药的合理性、安全性和有效性。

Abstrast

Shuanghuanglian Oral Liquid，composed of Chlorhydric acid，radix scutellariae and Fructus Forsythiae. It is a species of Chinese traditional medicine. The preparation procedure and quality inspection of Shuanghuanglian Oral Liquid were stuidied in this acticle. The optimum extraction process of preparation was carried out with orthogonal test，and the craft of extraction by the single factor experiment, and I suruey the corrigent to choose suitable quantity. This result would be technology parameters for production of Shuanghuanglian Oral Liquid. It has been identified whether chlorhydric acid or baicalin not. Chlorhydric acid and baicalin of preparation exist or not in by Tlc-scanning Method. This detective index could be used to control the quality of Shuanghuanglian Oral Liquid preparation. To determine the content of chlorphenamine maleate and baicalin by HPLC and UV-2000 and regulate the minimum limit as the control of preparation quality, in order to insure clinical management rationality, safety and usefulness.

我的意思是：把这个无限的想象空间留给各位，任由发挥。

一篇中药制剂分析文章，学习了。

学习了，。谢谢！

看样子你好久每上线了
能不能把这两种物质的紫外扫描结果传上来看看一起分析一下呢？
