The search for natural products to develop novel antimalarial drugs is challenging. Therefore, this study aimed to assess the antimalarial and toxicological effects of Chan-Ta-Lee-La (CTLL) and Pra-Sa-Chan-Dang (PSCD) formulations and their plant ingredients. The crude extracts of CTLL and PSCD formulations and their plant ingredients were evaluated for<jats:italic>in vitro<\/jats:italic>antimalarial activity using<jats:italic>Plasmodium<\/jats:italic>lactate dehydrogenase enzyme and toxicity to Vero and HepG2 cells using the tetrazolium salt method. An extract from the CTLL and PSCD formulations exhibiting the highest selectivity index value was selected for further investigation using Peter\u2019s 4-day suppressive test, curative test, prophylactic test, and acute oral toxicity in mice. The phytochemical constituents were characterized using gas chromatography-mass spectrometry (GC-MS). Results showed that ethanolic extracts of CTLL and PSCD formulations possessed high antimalarial activity (half maximal inhibitory concentration = 4.88, and 4.19 g\/mL, respectively) with low cytotoxicity. Ethanolic extracts of the CTLL and PSCD formulations demonstrated a significant dose-dependent decrease in parasitemia in mice. The ethanolic CTLL extract showed the greatest suppressive effect after 4 days of suppressive (89.80%) and curative (35.94%) testing at a dose of 600 mg\/kg. Moreover, ethanolic PSCD extract showed the highest suppressive effect in the prophylactic test (65.82%) at a dose of 600 mg\/kg. There was no acute toxicity in mice treated with ethanolic CTLL and PSCD extracts at 2,000 mg\/kg bodyweight. GC-MS analysis revealed that the most abundant compounds in the ethanolic CTLL extract were linderol, isoborneol, eudesmol, linoleic acid, and oleic acid, whereas ethyl 4-methoxycinnamate was the most commonly found compound in the ethanolic PSCD extract, followed by 3-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-4H-chromen-4-one, flamenol, oleic acid amide, linoleic acid, and oleic acid. In conclusions, ethanolic CTLL and PSCD extracts exhibited high antimalarial efficacy<jats:italic>in vitro<\/jats:italic>. The ethanolic CTLL extract at a dose of 600 mg\/kg exhibited the highest antimalarial activity in the 4-day suppressive and curative tests, whereas the ethanolic PSCD extract at a dose of 600 mg\/kg showed the highest antimalarial activity in the prophylactic test.<\/jats:p>","DOI":"10.1371\/journal.pone.0296756","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T18:25:41Z","timestamp":1704997541000},"page":"e0296756","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":10,"title":["Assessment of antimalarial activity of crude extract of Chan-Ta-Lee-La and Pra-Sa-Chan-Dang formulations and their plant ingredients for new drug candidates of malaria treatment: In vitro and in vivo experiments"],"prefix":"10.1371","volume":"19","author":[{"given":"Prapaporn","family":"Chaniad","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arisara","family":"Phuwajaroanpong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walaiporn","family":"Plirat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atthaphon","family":"Konyanee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdi Wira","family":"Septama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4826-9474","authenticated-orcid":true,"given":"Chuchard","family":"Punsawad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,1,11]]},"reference":[{"issue":"5","key":"pone.0296756.ref001","doi-asserted-by":"crossref","first-page":"572","DOI":"10.3390\/ph15050572","article-title":"Network pharmacology approach for medicinal plants: Review and assessment","volume":"15","author":"F Noor","year":"2022","journal-title":"Pharmaceuticals (Basel)."},{"key":"pone.0296756.ref002","doi-asserted-by":"crossref","first-page":"649820","DOI":"10.3389\/fphar.2021.649820","article-title":"The protective effect of polyherbal formulation, harak formula, on UVA-induced photoaging of human dermal fibroblasts and mouse skin via promoting Nrf2-regulated antioxidant defense.","volume":"12","author":"J Lohakul","year":"2021","journal-title":"Front Pharmacol"},{"key":"pone.0296756.ref003","doi-asserted-by":"crossref","first-page":"114977","DOI":"10.1016\/j.jep.2022.114977","article-title":"Traditionally used polyherbals in a southern African therapeutic context","volume":"288","author":"SF Van Vuuren","year":"2022","journal-title":"J Ethnopharmacol"},{"key":"pone.0296756.ref004","volume-title":"In: Natural Medicinal Plants","author":"GB Smita","year":"2021"},{"key":"pone.0296756.ref005","unstructured":"WHO.
