Background: Luffa cylindrica (L.) M. Roem. (Cucurbitaceae) is an herbaceous plant used for food as compose salads and do sweets and also used in traditional medicine as treat parasitic infections and intestinal diseases. Although this information, there are not many relates about anatomic characters for use in your quality control. Objective: The aim was investigating the anatomical characters of petiole and leaf blade and characterizing the metabolites in the leaf blade of L. cylindrica. Materials and Methods: Semipermanent histological slides were prepared for analysis of petiole and leaf blade in optical microscopy. Histochemical tests were also performed in the leaf blade. Results: The anatomical study revealed information about the type of trichomes, cuticle, vascular bundles and arrangement of the tissues that determine the botanical identity of this species. It was also identifying, for the first time, the presence of two types of trichomes in both of leaf blades faces. The histochemistry allowed determining which metabolites are in the leaf blade and also their location. Conclusion: The study described new characters for L. cylindrica and the results provide support to quality control of the species.

Background: Momordica charantia L. (Cucurbitaceae), is an herbaceous plant used for food and traditional medicine. It presents a proven antidiabetic activity in the literature, being a promising species for the development of phytotherapics. Objective: The objective was performing an anatomical study and characterizing the metabolites in leaves of M. charantia. Materials and Methods: Semipermanent histological slides were prepared for analysis of petiole and leaf blade in optical, polarization and scanning electron microscopy coupled with energy-dispersive X-ray spectrometry. Maceration and histochemical tests were also performed in the leaf blade. Results: The anatomical characterization revealed information about the type of trichomes, cuticle, vascular bundles and arrangement of the idioblasts and tissues that determine the botanical identity of this species. The histochemistry allowed determining the location of the metabolites and, along with the chemical microanalyses, to identify the type of crystal in the leaf blade. Conclusion: The study described new characters for M. charantia and the results provide support to quality control of the species.

Background: Croton cordiifolius Baill. is popularly known as \“quebra-faca\” in the Brazilian Northeast and is used to treat general inflammation, pain, and gastrointestinal disturbances. Objective: This paper aims to study the anatomical characteristics of C. cordiifolius. Materials and Methods: Cross-sections and paradermic sections of root, stem, petiole and leaf blade were obtained by hand and submitted to double staining with astra blue and safranin process for the anatomical study. Maceration was performed according to the method of Jeffrey. Results: The secondary root has peridermis, parenchymatic cortex, collateral vascular system surrounded by sclerenchyma. The secondary stem has peridermis, cortical region with lignified cells, isolated groups of fibers, laticifers, prismatic crystals, druses and starch. The vascular system of the stem is bicollateral. The petiole and the leaf blade have stellate, simple and glandular trichomes. The leaf blade is hypostomatic, with paracytic stomata. The mesophyll is isobilateral and the midrib shows a concave-convex contour. Laticifers occur in stem, petiole and leaf blade. Prismatic crystals and druses are found in all organs analysed. Through the maceration it was possible to identify the type of vessel elements. Conclusion: The anatomical features are useful for differentiation of other species of Croton and provide support to their quality control.

Background: Spondias mombin L. is fruit specie found in Tropical America and the coast of Africa, popularly known as cajazeira. Several researches with extract of leaflets show a diversity of promising pharmacological activities such as antibacterial activity, antiviral against dengue virus type 2, anti diabetic, among others. Objective: This paper aims to study the anatomical characteristics, phytochemical and histochemical from leaves of this species. Materials and Methods: Cross and paradermic sections from leaves were submitted to double staining with astra blue and safranin process for the anatomical study. Anatomical analysis of the structures was performed using an optical microscope. For ultra structure analysis, the leaf fragments, after processing and gold coating, were observed under scanning electron microscopy (SEM). The phytochemical analyses were performed using thin layer chromatography and the histochemical analyses using specific reagents for each metabolite group. Results: The leaf has anomocytic and tetracytic stomata distributed on abaxial surface. The midrib has convex symmetry with collateral vascular bundles in a closed arc disposition. The phytochemical showed the presence of mono and sesquiterpenes, triterpenes and steroids, hydrolysable tannins, phenylpropanoid glycosides, cinnamic derivatives and flavonoids. The histochemical tests allow us to state that phenolic compounds are found in the palisade parenchyma cells. Lignins can be found in woody vascular bundles and in perivascular sclerenchyma fibres. The volatile oils were evidenced in the schizogenous cavity, present in the parenchyma of the midrib. Conclusion: The results allowed characterizing anatomically the leaves of this species, outlining a profile of its phytochemical constituents and, in addition, determining which anatomical structures of storage of these metabolites by the plant.
