Resumo: ABSTRACT: Diabetes is a noncommunicable disease responsible for about 1.6 million deaths in 2016 worldwide. The use of medicinal plants is commonly reported in the literature as an adjuvant in the treatment of diabetes. Syzygium cumini (L.) Skeels, popularly known as azeitona preta or jambolão, is an important medicinal species of the Myrtaceae family used for diabetes. This work aimed to conduct an anatomical and histochemical study of the leaf blade of S. cumini. Semipermanent histological slides were prepared for analysis of the leaf blade in optical microscopy, polarization and scanning electron microscopy. Histochemical tests were performed in cross-sections of fresh leaf slides, using specific reagents for each group of metabolites. Microscopic analysis allowed the identification of important elements in the diagnosis of the species. The histochemical tests evidenced the presence of phenolic compounds, tannins, triterpenes and steroids, alkaloids, essential oils, lipophilic compounds, starch, lignin and calcium oxalate crystals. The results presented contribute to the pharmacobotanical standardization of the species. KEYWORDS: pharmacobotany, microscopy, Myrtaceae.

O uso de plantas medicinais é comumente relatado na literatura como adjuvante no tratamento de diabetes. Syzygium cumini (L.) Skeels, popularmente conhecida como azeitona preta ou jambolão, é uma importante espécie medicinal da família Myrtaceae, popularmente usada para diabetes. Este trabalho teve como objetivo realizar um estudo anatômico e histoquímico da lâmina foliar de S. cumini. Lâminas histológicas semipermanentes foram preparadas para análise da lâmina foliar em microscopia óptica, de polarização e microscopia eletrônica de varredura. Testes histoquímicos foram realizados em secções transversais de lâminas foliares frescas, utilizando reagentes específicos para cada grupo de metabólitos. A análise microscópica permitiu identificar elementos importantes no diagnóstico da espécie. Os testes histoquímicos evidenciaram a presença de compostos fenólicos, taninos, triterpenos e esteroides, alcaloides, óleos essenciais, compostos lipofílicos, cristais de amido, lignina e oxalato de cálcio. Os resultados apresentados contribuem para a padronização farmacobotânica da espécie.
