The dichloromethane-methanol (1:1 v\/v) extract from the stem bark of <jats:italic>Polyscias fulva<\/jats:italic> was evaluated for its <jats:italic>in vitro<\/jats:italic> and <jats:italic>in vivo<\/jats:italic> antifungal activities.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>The plant extract was prepared by maceration of its stem bark powder in CH<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub>-MeOH (1:1 v\/v). The extract obtained was successively partitioned in hexane, ethyl acetate and n-butanol. Phytochemical screening was performed using standard methods. <jats:italic>In vitro<\/jats:italic> antidermatophytic activity was assayed by the well diffusion and broth microdilution methods. The degree of dermal irritation of the crude extract was determined in guinea pigs using the occluded dermal irritation test method. The <jats:italic>in vivo<\/jats:italic> antidermatophytic activity of the extract-oil formulation (1.25, 2.5 and 5% w\/w concentrations) was evaluated using <jats:italic>Trichophyton mentagrophytes-<\/jats:italic> induced dermatophytosis in a guinea pigs model.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Phytochemical screening indicated that, the crude extract, ethyl acetate, n-butanol and residue fractions contain in general saponins, tannins, alkaloids, anthraquinones and phenols while the hexane fraction contains only alkaloids. The ethyl-acetate, n-butanol and residue fractions displayed higher antifungal activities (MIC = 0.125-0.5 mg.mL<jats:sup>-1<\/jats:sup>) against eight dermatophytes as compared to the crude extract (MIC = 0.5-1 mg.mL<jats:sup>-1<\/jats:sup>). This latter appeared to have slight perceptible erythema effects on guinea pigs as the primary irritation index (PII) was calculated to be 0.54. <jats:italic>In vivo,<\/jats:italic> the antidermatophytic activities of the extract-oil formulations were dose-dependent. Griseofulvin-oil 5% at 0.01 g\/kg and formulated extract-oil (5%) at 0.1 g\/kg eradicated the microbial infection after thirteen and fourteen days of daily treatment respectively.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>The results of preclinical <jats:italic>in vitro<\/jats:italic> and <jats:italic>in vivo<\/jats:italic> evaluations indicate that the extract-oil formulation at 5% may constitute an alternative means to alleviate fungal infections caused by dermatophytes.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1472-6882-13-95","type":"journal-article","created":{"date-parts":[[2013,5,6]],"date-time":"2013-05-06T02:23:38Z","timestamp":1367807018000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["In vitro and in vivo antidermatophytic activity of the dichloromethane-methanol (1:1 v\/v) extract from the stem bark of Polyscias fulva Hiern (Araliaceae)"],"prefix":"10.1186","volume":"13","author":[{"given":"Guy Sedar Singor","family":"Njateng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donatien","family":"Gatsing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raymond Simplice","family":"Mouokeu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul Keilah","family":"Lunga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jules-Roger","family":"Kuiate","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2013,5,6]]},"reference":[{"key":"1350_CR1","doi-asserted-by":"crossref","first-page":"240","DOI":"10.1128\/CMR.8.2.240","volume":"8","author":"I Weitzman","year":"1995","unstructured":"Weitzman I, Summerbell RC: The Dermatophytes.
