Analytical Methods in Environmental Chemistry Journal 2023-06-30T00:00:00+00:00 Hamid Shirkhanloo Open Journal Systems <p>The Analytical Methods in Environmental Chemistry journal&nbsp;is a peer-reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Analytical Methods in Environmental Chemistry&nbsp;publishes articles of modern analytical chemistry, cover innovations in the analytical techniques by nanotechnology, new analytical methods in Environmental and occupational health. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field. Traditional classical analytical methods such as spectrophotometry as well as established instrumentation methods such as atomic absorption spectrometry, gas chromatography, and <em>High-performance liquid chromatography</em> methods will be considered.</p> <p>&nbsp;</p> Analyzing plant extracts: Turmeric extracts on Leishmania Promastigotes and anti Leishmanial effect of Ginger: Using gas chromatography-mass spectrometry to examine ingredients 2023-05-22T01:24:01+00:00 Hedieh Zadeh-Abbasi Zarandi Leila Shirani-Bidabadi, Corresponding Author, Jafar Zolala Abass Aghaei-Afshar Ali Faghihi Zarandi Ehsan Salarkia Mostafa Eghbalian <p>Turmeric extract and aroma oil of <em>Curcuma longa</em> exhibit inhibition properties against various bacteria, parasites, and pathogenic fungi. We investigated the effects of Ginger (<em>Zingiber officinale</em>) and Turmeric extract on <em>Leishmania</em> promastigotes and used gas chromatography-mass spectrometry (GC-MS) for analyzing plant extracts. The hydroalcoholic extractions obtained from the two plants were diluted in 70% ethanol to three different concentrations; 12.5, 100, and 500 mg mL<sup>-1</sup>. The <em>Leishmania significant</em> strains were propagated in an artificial medium to reach sufficient parasites. The survival percentage of <em>Leishmania</em> promastigotes was affected significantly by the time and concentration of the extracts (P &lt; 0.05). The repeated measures pattern showed an interaction effect between various time points and treatment with the extracts. Statistics analysis showed a significant difference between different concentrations and extract samples (P &lt; 0.05). GC-MS showed that the survival rate of <em>Leishmania</em> promastigotes treated with hydroalcoholic extract of Ginger at 3-time points (24, 48, and 72 hours) was lower than Glucantime and Turmeric extract. The survival rate of promastigotes treated with Turmeric extract was similar to those treated with Glucantime but lower than those treated with a combined extract of Ginger and Turmeric at a concentration of 500 mg mL<sup>-1</sup>.&nbsp;</p> 2023-04-01T05:23:12+00:00 ##submission.copyrightStatement##
