Cytotoxicity of hexane, dichloromethane, ethanol and aqueous extracts of T. crispa stem against K562 cells was assessed. Crude extracts of T. crispa stem were obtained by sonication and maceration methods. T. crispa stem powder was macerated and … …OnLine Journal of Biological Sciences, Vol. 19, Issue 2 · 11 May 2019 · 7,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Garcinia kola Seed on Sexual Behavior and Testis Physiology in Wistar RatsJonah Sydney Aprioku, Victor Nwachukwu, Blessing Ukamaka Okeke et al.Garcina kola seed is believed by some to enhance male sexual performance but existing scientific data show divergent results. In this study, the sexual and reproductive influence of ethanol (70%) seed extract of G. kola was evaluated in Wistar rats. Adult male rats were gavaged with 0, 50, 100, 200 or 300 mg kg-1 day-1 of extract for 30 days … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 25 Apr 2018 · 13,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponse Surface Optimized Ultrasonic Assisted Extraction of Total Flavonoids from Walnut Leaves and In Vitro Antibacterial ActivitiesYuanda Song, Aydin Berenjian, Han Wu et al.In this paper, the optimum extraction conditions of total flavonoids extracted from walnut leaves subjected to Ultrasonic Assisted Extraction (UAE) were optimized by Response Surface Methodology (RSM). The mathematical model showed the high coefficient of measurement (R2 = 0.9938) which indicated that this model could be used to guide the response surface methodology. The optimum extraction parameters for extracting flavonoids … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractAmeliorative Impacts of Tribulus terrestris Against Ivermectin-Induced Hepato-Renal Toxicity in Rabbit: Pharmacological and Histopathological StudySally I. Ismaiel, Sameh M. Farouk, Raafat A. El-Ramady, Waleed F. KhalilThe current work aimed to investigate the protective effects of Tribulus terrestris extracts against ivermectin-induced hepatic and renal toxicity in male rabbit. Selenium plus vitamin E was used as a comparative standard drug to evaluate the efficacy of Tribulus terrestris extract on some hematological parameters, kidney and liver enzymes as well as associated histopathological changes. This work was carried out … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 12 Jan 2017 · 7,771 accessesView PDFCite
Literature ReviewOpen accessIn the abstractOptimization of Extraction of Cannabinoids and Flavonoids Substances from Influence Cannabis sp. and their Biological Activities before and after DecarboxylationOlga Kronusová, Michala Piklová, Kristýna Šírová et al.Inflorescence of eight different varieties of Cannabis sp. (3 hemp varieties and 5 medical cannabis varieties) were subjected to extraction with n-hexane or ethanol as representatives of non-polar and polar solvents. Crude extracts were either used directly or after decarboxylation of cannabis acids for measurement of selected biological activities-cytotoxicity against carcinogenic line B16 (musculus skin melanoma cells), cytotoxicity against Human … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 26 May 2022 · 6,741 accessesView PDFCite
