目的：对菠萝叶质量标准进行研究，以更好的开发应用菠萝叶的药用资源。方法：利用组织切片法观察菠萝叶组织结构；利用薄层层析法以菠萝酰酯为对照品进行定性鉴别；利用高效液相色谱法对主要成分进行含量测定。结果：菠萝叶镜下可分上下表皮层，其间有气孔；薄层层析可以清晰检测到菠萝酰酯成分；高效液相色谱法可以准确的测定菠萝叶中对香豆酸和菠萝酰酯的含量，且不同产地的菠萝叶中对香豆酸和菠萝酰酯含量差异较大，其中以云南的菠萝叶含量最高，广西的菠萝叶含量最低。结论：以菠萝酰酯作定性鉴别，以对香豆酸和菠萝酰酯为指标成分进行定量检测，可以较好的控制菠萝叶药材的质量。

This article was aimed to study the quality control of pineapple leaf in order to further develop the applications of pineapple leave as medicinal resources. The tissue structure of pineapple leaf was observed by tissue biopsy assay. Thin-layer chromatography (TLC) was employed on the qualitative identification of ananasate in the leave.The p-coumaric acid and ananasate were detected with high-performance liquid chromatography (HPLC) assay in the content determination. The results showed that pineapple leaf can be divided into the upper and lower leaf epidermis with stoma under microscope observation. Ananasate of the leave can be indentified clearly by TLC. HPLC method can accurately detect the content of p-coumaric acid and ananasate of pineapple leave. There are different contents of p -coumaric acid and ananasate of pineapple leave in different origins. In Yunnan province, the contents of p -coumaric acid and ananasate of pineapple leave are the highest; while the contents of p-coumaric acid and ananasate in Guangxi province are the lowest. It was concluded that ananasate can be used in the quality identification. The pcoumaric acid and ananasate can be used in the quantitative determination in the better control of the quality of pineapple leaf.
