Background: Tropaeolum tuberosum Ru{\i}z \& Pav{\'o}n {\textquotedblleft}mashua{\textquotedblright} is a native species of the central Andes and different propagation methods in vitro have been evaluated. However, this research has studied the in vitro propagation of 15 mashua (Tropaeolum tuberosum Ru{\'\i}z \& Pav{\'o}n) morphotypes from the Ayacucho and Apur{\'\i}mac regions (Peru) Objective: To evaluate the effect of the additives naphthaleneacetic acid (NAA) and 6-benzylamino purine (BAP) on the micro-propagation rate of T. tuberosum. Material and Methods: For in vitro establishment, seedlings were used after disinfection with sodium hypochlorite, propagated in Murashige and Skoog (MS) medium. For the evaluation of the effect of NAA and BAP additives, nodes were isolated from in vitro seedlings after 30 days of cultivation and transferred to MS medium supplemented with 3\% sucrose, pH 5.6 and 7 g/L of agar according to T1 (MS + NAA 1ppm) and T2 (MS + BAP 1ppm) treatments. The samples were cultivated for 28 days at 19 {\textdegree}C {\textpm} 2 {\textdegree}C with photoperiods of 16 h/light and 8 h/darkness. Results: After evaluating 20 repetitions for each of the three treatments, the addition of NAA or BAP does not improve the micropropagation rate of practically all the morphotypes studied. Furthermore, BAP behaved as an inhibitor of the development of mashua seedlings. Conclusion: The best micropropagation medium of Tropaeolum tuberosum Ru{\'\i}z \& Pav{\'o}n (mashua) is the basic Murashige and Skoog (MS) medium without the NAA or BAP additives.

Background: Tanacetum parthenium (L.) Sch Bip known as {\textquotedblleft}santa mar{\'\i}a{\textquotedblright} (Asteraceae family) is used in Peru for inflammatory diseases and also in colic, stomachache, headaches, diarrhea, among other. Objective: The aim was to determine the antioxidant profile, and analgesic effect of ethanolic extract of flowers and leaves of T. parthenium Material and Methods: Leaves and flowers of T. parthenium were soaked in 96\% ethanol and the obtained extract was analyzed using chemical reactions for identifying each secondary metabolite, 2,2-Diphenyl-1-picrylhydrazyl (DPPH) was used to determine the antioxidant capacity, and the antinociceptive effect was determined by using tail flick method. Results: Qualitative phytochemical study indicates the presence phenolic compounds, alkaloids, flavonoids, saponins and steroids in both extracts. In DPPH assay IC50 showed in leaves and flowers extract 452.10 {\textpm} 10.2 μg/mL and 270.70 {\textpm} 20.6 μg/mL respectively. The antinociceptive effect was better in leaves at doses 300 mg/ Kg than flower extract. Conclusions: The ethanolic extract of flowers of T. parthenium showed a high antioxidant activity and antinociceptive effect in mice.

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.
