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.

Objective: Various traditional systems of medicine enlightened the importance of Psychotria rubra (Lour.) Poir to have a great medicinal value. The present study was carried out to provide a scientific basis of the identification and the authenticity of Psychotria rubra (Lour.) Poir with the help of pharmacognostic parameters, which is not done before. Methods: Roots, stems, and leaves of P. rubra were collected for Pharmacognostic studies involving macros, microscopic evaluation, histochemistry and physicochemical parameters analysis like Ash value, Moisture content, Fluorescence analysis and Thin Layer Chromatography et al. Results: Transverse section of root was found like stone cells, calcium oxalate crystal and vessels in circular shape. Transverse section of stem showed the presence of lenticels and stone cell bands. Transverse section of leaf vein revealed the presence of shaft type of porosity. Powder microscopy revealed the presence of cork cells, stone cells, crystals and resin, fibers, needle crystal beam, thread tracheid and scalariform tracheid. Phytochemical investigation was found like alkaloids, flavones, carbohydrates, saponins, tannins and volatile oils. Results obtained in physicochemical parameters like Total ash value, acid insoluble ash and moisture content were 9.77\%, 0.68\% and 1.28\%, respectively. The leaching degree of P. rubra was higher in ethanol(75\%, v/v) and methanol solutions than that in chloroform, petroleum ether, and tetrachloromethane solutions. Thin Layer Chromatography (TLC) of the extract revealed 4 spots with the Rf values 0.47, 0.46, 0.46, 0.47 with the solvent system of chloroform: methanol: water: formic acid(7:3:1:0.1). Conclusion: The observations confirmed that P. rubra has an obvious Pharmacognostic characteristics, which will be useful towards providing a reliable basis for identification, purity, quality and classification of the plant.

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.

Introduction: Mahuwa i.e., Madhuca longifolia (Koen.) Macbr. Var. latifolia (Roxb) A. Cheval\  belongs to family Sapotaceae. The local people and aboriginals use the oil extracted from the seeds for cooking purposes. The powdered seed has several therapeutic uses too. Recently seed oil is used as biodiesel. Although seeds and oil are in use; deliberate attempt to study them has lacked. Methods: Pharmacognosy can be the first step in deciding the status of a plant organ as a crude medicine. Hence comprehensive Pharmacognosy of Mahuwa seed was carried out by macroscopy, microscopy, histochemistry, powder study, proximate analysis and preliminary phytochemical studies. Results: The present study provides the microscopic diagnostic characters such as presence of sclerides, oil ducts, crystals etc in seed. Physicochemical studies revealed total ash (0.65\%), acid insoluble ash (0.5\%), water soluble ash (5.95\%), alcohol soluble extractive (23.04\%) water soluble extractive (17.76\%) and chloroform extractive (12.3\%). Histochemistry and Preliminary phytochemical screening revealed the presence of saponnins, terpenoids, anthraquinone glycoside, cardiac glycoside etc. Conclusion: These studies will help in establishing the \ pharmacopeial standards for the said drug.
