摘要
目的：对不同产地的两种丹参用差示扫描量热（ DSC）法进行分析鉴别，鉴别内容包括：原药材粉末、水提物和醇提物。方法以α-Al2 O3作为对比参比物，在静态空的气气氛，以8mW差示扫描量热（DSC）量程，以10℃/min的升温速率，在25-400℃的温度范围下，根据实验所得到的特征和图谱峰进行比较。结果同产地的两种丹参原药材粉末、水提物和醇提物差示扫描量热（ DSC）图谱峰形基本一致，仅放热峰温略有不同。结论实验表明差示扫描量热（ DSC）法具有试量微样化、不用溶剂、曲线易于解析、快速简便等优点，可作为不同产地丹参及其提取物的鉴别方法之一。
Abstract
Objective Two kinds of Salvia Miltiorrhizae from different sources by differential scanning calorimetry ( DSC) analysis identification,identification in-clude:raw material powder,water extract and alcohol extract.Methods The alpha-A l2O3 as comparative reference substance in the atmosphere,static empty,with a 8 mW differential scanning calorimetry(DSC)range,with 10℃/min heating rate,in the temperature range of 25-400℃,according to the comparison of the characteristics and the spectrum peak.Results Different origin of two kinds of Salvia miltiorrhiza powder ,water and ethanol extracts of differential scanning calorimetry ( DSC) spectrum peak is basically the same,only the exothermic peak temperature slightly different.Conclusion experiments show that the differential scanning calorimetry(DSC)method has a small amount of test sample,no solvent,curve is easy to resolve,quick,can be used as one of the method to identify and extract of Radix Salviae Miltiorrhizae from different habitats.
