Research ArticleOpen accessIn the abstractAntioxidant Properties and Dose-Dependent Effects of Monkey Fruits (Artocarpus lakoocha) against Paracetamol-Induced Hepato-Renal Toxicity in RatsMd. Yousuf Ali, Md. Reaz Morshed, Md. Sakib Hossen et al.In this study, the antioxidant potentials and protective effect of ethanolic extract of monkey fruits (Artocarpus lakoocha) (AL) was investigated against paracetamol-induced toxicity in rats. AL which contains high concentration of polyphenols, flavonoids, tannins and protein, exhibited high radical scavenging activity and ferric reducing antioxidant power. Administration of paracetamol (500 mg/kg) for seven consecutive days caused severe oxidative stress in … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 26 Nov 2018 · 8,337 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Identification of Molecules in a Thin-Film Extract Combined with LaserTheodore Guié Toa Bi, Sié Ouattara, Alain ClementThis paper presents the automation of the thin-layer chromatography technique whose separation and identification of molecules present in a mixture are currently done manually and laboriously. We have therefore found an interest in automating this technique. In this part, the method implemented comprises 2 steps. First we proceeded to the segmentation of the spots obtained on the chromatographic plate. We … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 14 Nov 2018 · 7,089 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Studies on Proximate Composition and Phytochemical Screening of Mango, Key lime, African star apple and African pear Seeds as Possible Coagulant Aids for Water TreatmentAnimetu Seghosime, Johannes Akpabla Mawuli Awudza, Richard Buamah, Sampson Oduro KwartengMany fruits including mango (Mangifera indica), key lime (Citrus aurantiifolia), African star apple (Chrysophyllum albidum) and African or bush pear (Dacryodes edulis) are nutritionally valuable as human food, however after consumption of the fruits, their seeds are discarded as wastes since they are of no commercial value and this results in disposal problems. Hence assessment of the constituents of such … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 12 Aug 2017 · 9,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalgesic and Anti-inflammatory Activity of Euphorbia antiquorum LinnBanibrata Das, Samina Alam, Rajib Bhattacharjee, Biplab Kumar DasEuphorbia antiquorum (L.) is used as traditional medicine for various ailments in Bangladesh. But the scientific basis for its use especially in pain and inflammation remains largely unknown. Therefore, the present study was designed to evaluate analgesic and anti-inflammatory effect of the aqueous ethanolic extract of the whole plant. The analgesic activity was evaluated by hot plate, acetic acid induced … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 2 · 27 Aug 2015 · 9,211 accessesView PDFCite
