5个不同地区市售乳香质量评价及易掺伪品松香的检查

Quality evaluation of Olibanum marketed in 5 different areas and identification of rosin

目的对5个不同地区市售乳香进行质量评价及易掺伪品松香检查。方法采用气相色谱法对其来源进行鉴定,以乳香中的特征成分11-羰基-β-乙酰乳香酸为对照品采用高效液相色谱法进行含量测定;理化鉴别,薄层鉴别来确定乳香中是否添加松香;以松香中的特征成分松香酸为对照品采用高效液相色谱法进行含量测定。结果经气相色谱法鉴定结果表明5个不同地区市售乳香均为埃塞俄比亚乳香,经高效液相色谱法测定5个不同地区的市售乳香中的11-羰基-β-乙酰乳香酸含量均大于3.5%;理化和薄层鉴别后表明5个不同地区的市售乳香中均不同程度的掺有松香;经高效液相色谱法测定5个不同地区的市售乳香中的松香含量均小于0.1%。结论经测定不同地区市售乳香,其中11-羰基-β-乙酰乳香酸含量均符合标准;虽然松香含量较低,但其掺伪现象仍比较普遍,应加大监管力度。该实验所建立的检测方法,可为掺伪物松香定性定量检测提供参考。

Objective Quality evaluation of Olibanum marketed in 5 different areas and identification of rosin which is commonly adulterated in Olibanum. Methods Gas chromatography was used to identify the source. We compared the samples with standard using physicochemical identification, thin layer chromatography and high performance liquid chromatography methods.Results The results show that the 5 different regions of commercially available olibanum all from Ethiopia. 11-beta carbonyl acetyl boswellic acid was detected in 5 different regions,and all the content were more than 3. 5%. Rosin acid was detected in 5 different regions,and all the content were less than 0. 1%. Conclusion The 11-beta carbonyl acetyl boswellic acid all conform to the standard Although the content of the rosin is low,the phenomenon of counterfeit and falsify in olibanum commercial samples is serious,the relevant department should strengthen supervision. The method we developed can meet the requirements of identification and determination.
