肉桂道地产区与GAP基地药材及商品药材的质量对比研究

目的评价道地产区及GAP基地肉桂药材的质量,并与商品药材进行比较。方法高效液相色谱法测定肉桂中桂皮醛的含量。以桂皮醛的含量为指标,结合对含油量、总灰分、酸不溶性灰分等的考察评价药材的质量。结果各样品总灰分和酸不溶性灰分均符合要求。道地产区和GAP基地药材挥发油含量和桂皮醛含量均符合药典规定,商品药材含油量和含醛量波动大。结论道地产区与GAP基地药材质量好,且较稳定,商品药材质量不稳定。

Comparison Study on the Quality of Cortex Cinnamomi from Genuine Producing Areas, GAP Planting Base and Commercial Markets

Objective To evaluate the quality of Cortex Cinnamomi from genuine producing areas and GAP planting base,and to compare with those of the commercial medicinal materials.Methods A RP-HPLC method was carried out to determine the content of cinnamyl aldehyde in cortex cinnamomi.Combined with the comparison of volatile oil yield,total ash content and acid-insoluble ash content,the quality of the samples was evaluated with the index of cinnamyl aldehyde content.Results The total ash contents and acid-insoluble ash contents of all samples were in the normal range.Cinnamyl aldehyde contents and volatile oil yields for samples from genuine producing areas and GAP planting base were up to the pharmacopoeia.There was a great fluctuation in cinnamyl aldehyde contents and volatile oil yields in commercial materials.Conclusions The quality is good and stable for the samples from genuine producing areas and GAP planting base,but it is not stable for the commercial materials.
