用热分析技术和红外光谱法鉴别花鹿茸的研究

IDENTIFICATION OF PILOSE ANTLER OF SIKA BY THERMAL ANALYSIS AND IR

热分析技术可用以快速鉴定花鹿茸的组成，差热曲线显示花鹿茸的失水峰的外延起始温度为３８．９℃，其所含蛋白质的热解外延起始温度３０５℃。热重曲线显示花鹿茸含水分８．２９％，含蛋白质４０．２８％，含无机物５１．００％，应用差热分析法求花鹿茸细粉的热解活化能，未角化的内部组织的平均热解活化能为１３．１３ＫＪ／ｍｏｌ（ＳＤ＝０．１２ＫＪ／ｍｏｌｎ＝３），表皮层的平均热解活化能为４３．０９ＫＪ／ｍｏ１（ＳＤ＝６．２８ＫＪ／ｍｏｌ，ｎ＝３），表皮层的热解活化能比之未角化的内部组织的热解活化能大。红外光谱确定花鹿茸在２８０～４８０℃热解的有机物为蛋白质类，其无机物残渣为骨炭，花鹿茸在１５０℃以下有良好的稳定性。

Thermal analytical technique was used as a rapid means for the identification of pilose antler sika.DTA curve showed that the extra-expolation temperature of the water and the proteins in pilose antler were 38.9℃ and 305.0℃ respectively.TG curve showed that pilose antler of sika contained 8.29% of water,40.28%of proteins and 51.0% of inorganic compounds, The proteins degradating ranging from 280℃ to 480℃ were identified by IR,The residue after the degradation was bone black.The powder of pilose antler of sika was quite stable below 150℃.
