通常,生药中挥发性成分的含量是较难准确测定的。特别是含量甚微的成分,更不用说测定其含量了。Okugawa 等创造了一种新方法,即吸香(?)色谱联用技术,使这一问题得到了解决。吸香法是提取香料的一种技术,利用这种技术,先使生药中具升华性或挥发性成分充分地被油脂吸收,然后用适当的溶剂提取。经色谱分析,可以有效地进行定量分析。这种方法简便易行。例如,用吸香(?)色谱技术测定牡丹皮和芍药根中牡丹酚的含量,具体操作如下:
In general, the content of volatile components in crude drugs is difficult to determine accurately. In particular, very little content, let alone determine its content. Okugawa et al. have created a new method, namely aromatization (?) chromatography, which has solved this problem. The method of extracting a fragrance is a technique for extracting a fragrance. By using this technique, sublimation or volatile components are fully absorbed by fats and oils in a crude drug, and then extracted with a suitable solvent. Chromatographic analysis can effectively perform quantitative analysis. This method is simple and easy. For example, using aroma (?) chromatographic techniques to determine the content of phytol in peony bark and peony root, the specific operation is as follows:
