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 abstractAnti-Inflammatory, Analgesic and Antioxidant Activities of Allophylus Cobbe LeavesPreeti Jain, Md. Selim Hossain, Kaniz Fatema et al.Allophylus cobbe L. Raeuschel (Family-Sapindaceae) is a medicinal plant used traditionally for the treatment of various health risks like pain, inflammation, ulcers and wounds in Bangladesh. This study determined the polyphenolic compounds and evaluated the analgesic, anti-inflammatory and antioxidant effects of the ethanol extract of Allophylus cobbe leaves. High Performance Liquid Chromatography (HPLC) analysis was used to determine the polyphenolic … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 4 · 27 Jan 2015 · 8,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractAMELIORATIVE EFFECT OF HIBISCUS SABDARIFFA LINN ON SUBCHRONIC CHLORPYRIFOS-INDUCED ALTERATIONS IN SEX AND THYROID HORMONES IN MALE WISTAR RATSShittu Muftau, Olatunji Omobolanle Aisha, Suleiman Folorunsho Ambali et al.Studies have shown that Chlorpyrifos (CPF), an Organophosphate (OP) insecticide alters both sex and thyroid hormones. Apart from inhibiting Acetylcholinesterase (AChE) activity, CPF has been shown to cause oxidative stress. The antioxidant potentials of many flavonoid-containing plants are increasingly being exploited in the therapy of many infectious and non-infectious diseases. Hibiscus Sabdariffa (HS) is one of the most widely used … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 20 Feb 2014 · 9,097 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Green Tea on Hepatic Cells Under the Influence of Inflammatory Conditions: In Vitro StudyIbrahim G. Saleh, Zulfiqar Ali, Farid M. Hamada et al.The concern about safety of consumption of Green Tea (GT) supplements has become a scope of many studies. We and others have described earlier the effect of the administration of GT and its polyphenols on liver in a mouse model. In this study we aimed to investigate the effect of GT on HepG2 cells. HepG2 cells were treated with different … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 4 · 3 Dec 2013 · 7,314 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Palm Oil with Methane Avoidance at Palm Oil Mill: A Case Study of Cradle-to-Gate Life Cycle AssessmentChiew Wei Puah, Yuen May Choo, Soon Hock OngThe study discusses a case study of cradle to gate life cycle assessment for the production of Crude Palm Oil (CPO) with methane avoidance at palm oil mill.

Research ArticleOpen accessIn the abstractIn Vitro Prevention of Browning in Plantain CultureInnocent Chimereze Onuoha, Chinonye Jemimah Eze, Chibuikem I.N. UnambaProblem statement: The in vitro propagation of plantain (Musa paradisiaca) is still faced with lots of challenges such as blackening or browning of tissues prior to culture due to the oxidation of phenolic compound by polyphenolic oxidase enzyme present in the tissue when excised. Approach: Understanding browning processes in plantain and possible ways of minimizing it during excision of explants … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 15,229 accessesView PDFCite
Research ArticleOpen accessIn the abstractFungal Culture Systems for Production of Antioxidant Phenolics Using Pecan Nut Shells as Sole Carbon SourceMiguel A. Medina, Ruth E. Belmares, Antonio Aguilera-Carbo et al.Problem statement: Many agro-industrial wastes have little or none utilization, when these materials could be a very rich source of several value-added compounds, such as: the pecan nut shells, which contain Antioxidant Phenolic (AP) molecules like tannins. Approach: In this study, a bioprocess for the liberation of AP from Pecan Nut Shells (PNS) was described. A chemical characterization of raw … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,042 accessesView PDFCite

However, most of these extract have been obtained using solvents no allowed under an organic production context. Approach: In the present research was to evaluate the inhibitory effect of polyphenolic extracts from L. graveolens and C. illinoensis, obtained with alternative organic solvents (lanolin … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Flavonoid, Quercetin, Inhibits HIV-1 Infection in Normal Peripheral Blood Mononuclear CellsMadhavan P.N. Nair, Zainulabedin M. Saiyed, Nimisha H. Gandhi, C. N. RamchandProblem statement: Flavonoids and related polyphenols, have been known to possess cardioprotective, anti-tumor, anti-inflammatory, anti-allergic and anti-viral activities. Previous studies have shown that flavonoid, quercetin significantly downregulates expression of pro-inflammatory cytokines in cultured cells via modulation of NFκB and p38MAPK signaling pathways. In the current study, we hypothesize that quercetin exerts anti-HIV activity by differential modulation of pro-and anti-inflammatory cytokine … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 12,184 accessesView PDFCite
