Background: Luffa operculata is a vegetable species well known in the traditional peruvian medicine for its many medicinal properties and cosmetic applications. Objective: The aim objective was to determine the pharmacognostic characteristics of L. operculata as well as observing the pharmacological effect of the ethanol extract of L. operculata fruit on chronic inflammation in rats. Materials and Method: Phytochemical analysis was carried out by using specific chemical reagents for each constituent chemical, the pharmacobotanical study was done with a histological tinction (fruit, steam and leaves), which were stained with Safranin 1\% and Toluidine blue 1\%; the chronical inflammation was assessed by air bag method in Holztman male rats. Doses of 100, 250 and 500 mg/Kg were tested in order to determine the anti-inflammatory effect, which was demonstrated with histopathological evaluation and lymphocytes reduction. Results: The main findings indicate that the ethanolic extract presented saponins, alkaloids, carbohydrates, terpenes and steroids. The efficiency of lymphocyte reduction per field in the histopathological study of the granuloma was 58.4\% with the middle dose of 250 mg/kg (p \< 0.0001), which gives a dose-independent anti-inflammatory effect in rats. Conclusion: Luffa operculata presented anti-inflammatory effect at 250 mg/Kg by oral administration in a chronical experimental model of inflammation in rats.

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.
