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.

Introduction: Phytochemicals are frequently used in chemotherapeutic treatment or may be used as chemo preventive agents with chemoprevention. The study report the quantification of phytochemical constituents and vitamin C contents from ethanol extracts of Solanum torvum fruits. Method: The main objective for this research was to use standard procedures to determine phytochemical and vitamin C content. Results: The estimated alkaloids found in mature fruits were 6.32 \± 0.12 mg/g and 16.94 \± 2.3 mg/g in the immature fruits. Total saponins in mature and immature fruits were 8.60 \± 2.6 mg/g and 16.90 \± 9.4 mg/g respectively. Total flavonoids in mature and immature fruits were 21.14 \± 4.4 mg/g and 14.24 \± 1.8 mg/g respectively. Also vitamin C contents were 11.79 \± 2.0 mg/g in mature fruits and 8.70 \± 0.26 mg/g in immature fruits. With the exception of alkaloids whose difference in the mature and immature was significant, other differences obtained were not significant. Conclusion: The study showed that the extracts contain diversity of phytochemicals in appreciable amount that can expertly keep the body against oxidative stress triggered by free radicals and therefore be used as a source of potent natural products.

Background: Spathodea campanulata (P. Beauv.) Bignoniaceae extract\ (SCE) is one of many herbal medicines\ used widely in Ugandan traditional\ medicine for various ailments. Generally most of these herbal\ medicines\ are yet to be standardized or have their phytochemical content characterized.\ Method: This study identified the secondary metabolites in the stem bark\ methanolic extract and quantified them. The same extract was subjected\ to serial solvent fractionation, TLC characterization and antidiabetic testing.\ Results: The secondary metabolites were found to comprise of 7.5\% alkaloids,\ 10\% flavonoids, 13\% tannins and 17\% saponins per gram of plant material.\ The TLC characteristics of the fractions (hexane (HX), ethylacetate (EA)\ and methanol (ME)) viewed under UV light revealed spots with the following\ Rf values; the hexane partition gave HX7EA3 (0.96 and 0.68) HX9EA1\ (0.68 and 0.3), EA1ME9 (0.86 and 0.58), EA3ME7 (0.87), EA7ME3 (0.85)\ and EA9ME1 (0.85). The ethylacetate partition gave the following HX1EA9 (0.53, 0.34 and 0.18), HX3EA7 (0.59, 0.40 and 0.26). Discussion: All the\ fractions produced nominal reduction of hyperglycemia. Except hexane\ fraction at 50 mg/kg and ethylacetate fraction at 200 mg/kg all the fractions\ had percentage reductions of glucose greater than that of the control at\ the experimental doses. Although the values of percentage reductions of\ hyperglycemia by the hexane fraction were apparently dose-dependent,\ the greatest margin of reduction of hyperglycemia was observed in the\ residual aqueous fraction. Conclusion: It was found that SCE contains\ valuable phytochemicals in appreciable quantities which are antidiabetic.\ The residual aqueous fraction is the most potent antihyperglycemic of the\ solvent fractions.
