Objective: To evaluate the antioxidant capacity of Chuquiraga spinosa extracts and prevention of carrageenan-induced inflammation in mice. Methodology: Experimental design: plant species, erythrocytes and male BALB C53 mice, were considered as biological material. Antioxidant capacity was evaluated in 50\%, 70\%, 96\% and aqueous ethanolic extracts by 2,2-Diphenyl-1-Picrylhydrazyl reduction, malondialdehyde inhibition in oxidized erythrocytes with H2O2 and correlating with polyphenol content equivalent to gallic acid/gram dry extract. Inflammation was evaluated by inoculating carrageenan 2\% in "subcutaneous air bag" of mice: 1) White, 2) carrageenan, 3) dexamethasone 2 mg/kg, 4-6) ethanolic extract 70\% doses 100, 250 and 500 mg/kg respectively; determining nitric oxide, malondialdehyde, total proteins, albumin, leukocytes in exudate and histological changes. Results: Alkaloids, flavonoids, terpenes, phenolic compounds, tannins, carbohydrates, triterpenes, steroids and sesquiterpene lactones were identified; aqueous extract presented greater reduction of 2,2-Diphenyl-1-Picrylhydrazyl (CI50 = 58.99 μg/mL), ethanolic extract 70\% presented greater inhibition of malondialdehyde in erythrocytes (CI50 = 16.44 nm/mL); It was observed that the higher the amount of polyphenols, the greater the reduction of 2,2-Diphenyl-1-Picrylhydrazyl (r=-0.909) and the greater the inhibition of malondialdehyde (r=-0.781). With 500 mg/kg of 70\% ethanolic extract there was greater anti-inflammatory effect inhibiting malondialdehyde, nitric oxide, albumin, total proteins and leukocytes in 55.55\%, 81.92\%, 41.20\%, 31.51\% and 32.45\% (p\<0.01) respectively and less infiltration of leukocytes and lymphocytes in air sac membrane. Conclusion: The extracts of aerial parts of Chuquiraga spinosa showed antioxidant capacity correlated to polyphenol content. The 70\% ethanolic extract prevented inflammation in mice in a dosedependent manner.

Objective: To determine the ameliorative effect of the ethanolic extract of Chuquiraga spinosa (ChS) on 7,12-Dimethylbenz[a]anthracene (DMBA)-induced breast cancer in rats. Methods: 36 female Holztman rats were divided into 6 groups. I) The negative control group received physiological saline (PS). II) ChS-200 group received 200 mg/kg of ChS. III) DMBA group was induced with DMBA (20 mg/Kg) dissolved in PS and administrated orally for 15 weeks. IV) DMBA + ChS-50 group, V) DMBA + ChS-250 group, and VI) DMBA + ChS-500 group, which received the extract orally for 15 weeks after DMBA induction. All data were expressed as mean and standard deviation. One-way analysis of variance (ANOVA) followed by Dunnet test was carried out to compare the mean value of different groups Histopathological analysis was evaluated by using Image J software. Results: Hematology showed that the triglyceride level was significantly lowered (P\< 0.01) and high-density lipoprotein (HDL) level was significantly increased (P \<0.01) in groups III, IV and V. Also, ChS extract significantly lowered the C reactive protein (CRP) level (P \<0.01) and malondialdehyde level (P\<0.05). There was a significant decrease in the frequency of DMBA-induced micronucleated polychromatic erythrocyte (P\<0.01). Conclusions: Chuquiraga spinosa showed an ameliorative effect on DMBA-induced breast cancer in rats as well as antioxidant, antitumor and antigenotoxic properties.

Introduction: Plukenetia volubilis is known as Sacha Inchi (SI) is originary from the peruvian amazone and it has been cultivated and consumed since the pre and Inca{\textquoteright}s time. Objective: Sacha inchi oil was assessed for genotoxicity in Balb C albino mice and subchronic toxicity in goldfish (Carassius auratus). Material and Methods: The genotoxicity was assessed in Mus musculus Balb C (n = 25) separated into five groups randomly selected of twenty-five each one. Groups were 10 mL / kg normal saline (NS), 40 mg / kg cyclophosphamide group (CP) and the three other groups received cyclophosphamide and sacha inchi oil of concentrations 10, 100 and 1000 mg / kg respectively. The substances were administered three times during 24 hours. The genotoxicity in mice was evaluated determining micronucleus levels in blood and bone marrow. The subchronic toxicity was assessed in goldfish (Carassius auratus) (n = 48) separated into four groups randomly selected of six each: normal saline group (control) and three groups that received doses of 10, 100 and 1000 μg sacha inchi oil per litre of water respectively for 45 days. Results: The values of weight, length, growth rate, condition factor (K) and number of survivors were recorded. CP group showed higher micronuclei levels in blood and bone marrow compared with sacha inchi oil 10, 100 and 1000 mg / kg groups (ANOVA Test p \<0.01 Scheffe{\textasciiacute}s Post Hoc p \<0.05, p \<0.01 and p \<0.001 respectively). The subchronic toxicity assessment in goldfish showed isometric growth, a decline in "K" and a similar specific percentage growth rate per day in all groups (ANOVA test p\> 0.05). Conclusion: Sacha inchi oil was not toxic under experimental conditions.

Background: Gastric cancer (GC) is one of the most frequent diseases in human population: Many plants from Peruvian flora is used to treat cancer as alternative treatment. Chuquiraga spinosa Lessing (ChS) is a species with high potential therapeutic due to its antioxidant and anti-inflammatory effect as well as protective against prostate cancer. Objective: The main objective was to evaluate the possible protective effect of Chuquiraga spinosa extract on NMU (N-methyl-N nitrosourea)-induced gastric cancer in rats. Methods: Gastric carcinogenesis was induced in 30 male Holtzman rats by providing NMU 50 \μg/Kg by oral administration for 16 weeks. Ethanolic extract of ChS aerial parts was administered at doses 50, 250 and 500 mg/Kg per oral. The protective effect was determined through weight controls, biochemical and hematological parameters; the antioxidant capacity by superoxide dismutase (SOD), nitric oxide (NO), malondialdehyde (MDA) and anti-inflammatory capacity by the level of C-reactive protein (CRP). The tumors were monitored by using histological examinations. Results: Oral administration of Chuquiraga spinosa extract significantly decreased superoxide dismutase malondialdehyde, nitric oxide, C-reactive protein levels (p\<0,01, p\<0,01, p\<0,01 and p\<0,01 respectively compared with Inductor group). There was a significant increase in the weights of animals (P\<0.05). Conclusion: Considering the anti-inflammatory, antioxidant, and anticancer properties of Chuquiraga spinosa extract, we conclude that it has a protective effect on NMU induced gastric cancer in rats.
