(CFL) fruit is one of such plants used locally to treat fever and malaria. However, there is dearth of information on the most promising <em>in vivo</em> antiplasmodial candidate between crude and solvent-partitioned extractions in animal models. Water, ethyl acetate, and n-hexane were used to extract, assess, and compare the <em>in vivo</em> antiplasmodial activity of CFL crude extracts and solvent-partitioned extracts in chloroquine-sensitive <em>Plasmodium berghei (</em>NK-65)-infected mice. 368 adult albino mice (both sexes) were used; 56 females for toxicity tests, 136 for three extracts and 176 for four fractions using suppressive and curative models. Mice were randomly grouped into five (n = 4) for treatment, while a group for control and a group for choroquine were separately maintained throughout for the crudes and fractions. Group A= 0.2 ml normal saline, group B= 10 mg/kg body weight chloroquine, while groups C-G= 0.5, 1.0, 2.0, 4.0, 8.0 mg/kg body weight CFL respectively for each extract and fraction. All experiments were performed using standard methods. LD₅₀ for both crude extracts and solvent fractions was &gt; 20 mg/kg. Aqueous extract had better antiplasmodial performance among the three extracts while residual fraction did among the four fractions, for both suppressive and curative models. Aqueous fractions had higher concentrations of metabolites, better <em>in vivo</em> antiplasmodial activities, and more prolonged lifespan than crude extracts. CFL administration significantly resisted body weight loss, drop in packed cell volume, and fall in rectal temperature caused by the parasites. This action was more prominent in the fractions than in extracts, especially at 2.0 mg/kg. Therefore, this study established that aqueous extraction is preferable for <em>Capsicum</em> and that crude extraction is not sufficient to harness the <em>in vivo</em> antiplasmodial potential, hence justifying use of water for the preparation in local communities as alternative medicine.</div></div>","PeriodicalId":101014,"journal":{"name":"Pharmacological Research - Natural Products","volume":"6 ","pages":"Article 100169"},"PeriodicalIF":0.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study evaluated the anti-motility and anti-secretory properties and phytochemical constituents of the leaves of <em>Annona muricata</em>.

Our results indicate that mice treated with MEBCR was able to control the L-arginine-induced changes in pancreatic enzymes, oxidative stress markers (MDA, GSH and nitrite), pancreatic inflammatory markers (MPO, IL-1β, TNF-α and IL-6) as well as histological changes in the pancreatic and liver tissues. MEBCR dose dependently decreases the pro-inflammatory cytokines levels such as TNF-α, IL-6, and IL-1β. MEBCR improved the antioxidant defence by improving Nrf-2 and SOD-1 expression. When considered collectively, our findings indicate that MEBCR pretreatment inhibits AP. These outcomes may be related to the antioxidant activity of the antioxidant enzyme, which was brought about by the Nrf2/ARE signaling pathway being activated.
