Abstract

El presente estudio tuvo como objetivo caracterizar la anatomía e histoquímica del tallo y las hojas de Jasminum azoricum L. Para ello, se realizaron preparaciones histológicas semipermanentes que contenían cortes transversales de tallo y hoja, además de cortes paradérmicos de la lámina foliar, analizados por microscopía óptica. También se realizaron pruebas histoquímicas para verificar la ubicación de acumulación de constituyentes químicos en secciones transversales de la hoja. Las caracterizaciones anatómicas aportaron importantes datos para distinguir las especies y el estudio histoquímico reveló los sitios de síntesis y/o almacenamiento de los metabolitos que poseen importantes propiedades medicinales. The present study aimed to characterize the anatomy and histochemistry of the stem and leaves of Jasminum azoricum L. Thus, semi-permanent slides were prepared containing transverse sections of the stem and leaf, in addition to paradermal sections of the leaf blade, analyzed by optical microscopy. Histochemical tests were also carried out in order to verify the site of accumulation of chemical constituents in cross-sections of the leaf blade. The anatomical characterizations allowed the identification of important characteristics to distinguish the species and the histochemistry revealed the sites of synthesis and/or storage of the metabolites. The results found help to identify the species studied and point out possible metabolites that have considerable medicinal properties.

茉莉茎叶的解剖学和组织化学研究。
这项研究的目的是描述茉莉花茎和叶的解剖和组织化学。为此,进行了半永久性的组织学准备,其中包括茎和叶的横向切片,以及光学显微镜分析的叶片的非热切片。还进行了组织化学测试,以验证化学成分在叶片横截面上积累的位置。解剖特征为区分物种提供了重要数据,组织化学研究揭示了具有重要药用特性的代谢物的合成和/或储存地点。本研究旨在表征茉莉属植物茎和叶的解剖和组织化学。因此,除了用光学显微镜分析叶片的反常截面外,还制备了含有茎和叶横截面的半永久性薄片。还进行了组织化学测试,以验证叶片横截面中化学成分积累的位置。解剖特征使识别重要特征以区分物种成为可能,组织化学揭示了代谢产物的合成和/或储存地点。发现的结果有助于确定所研究的物种,并指出可能具有相当大药用特性的代谢产物。
