Objectives: The main aim of this study is to apply smart, simple, rapid and accurate methods for simultaneous determination of Paracetamol (PAR), Chlorzoxazone (CXZ) and Diclofenac potassium (DIC), in their bulk powder and tablet dosage form. Methods: Potent processing methods were used which were based on the application of continuous wavelet transform (CWT) and Savitsky–Golay derivatization (SAVGOL) as univariate spectrophotometric methods, partial least squares (PLS) and synergy interval partial least squares (siPLS) as multivariate methods. Results: PAR, CXZ and DIC were determined in the concentration ranges of 2–30, 2–50 and 2–30 μg/mL, respectively. The regressing and validation parameters of the proposed methods revealed the efficiency of the methods. The results obtained for the analysis of those drugs by the proposed methods were statistically compared to those obtained by applying a reported high performance liquid chromatographic method. Statistical comparison was done, and no significant difference was found between the proposed methods and the reported one. Conclusion: Successful determination of ternary mixture containing PAR, CXZ and DIC was achieved with no need for tedious sample separation or pre-treatment derivatization which is considered a great benefit in quality control laboratories.

Results: From the aqueous methanolic extract of Euphorbia retusa forssk. aerial parts seven known phenolic compounds; kamferol-3-O-β-D- glucopyranoside (1), quercetin -3-O-β-D- glucopyranoside (2), 3,3`dimethoxy ellagic acid (3), ellagic acid (4), gallic acid (5), kamferol (6) and quercetin (7) were isolated and identified by chromatographic and spectroscopic analysis. Administration of the extract (100 and 200 mg/kg body weight) significantly decreased the AST and ALT levels, inhibited the CCl4 -induced elevated levels of NO and MDA and increased the level of hepatic GSH. A comparative histopathological study of liver exhibited almost nearly normal architecture as compared to toxicant group. Conclusion: Euphorbia retusaextract has shown to have hepatoprotective activityon CCl4-induced liver damage in rats which might be attributed to its phenolic contents.","PeriodicalId":15017,"journal":{"name":"Journal of Advanced Pharmacy Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88156678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: This study aimed at phytochemical investigation of the 70% alcoholic extract of Erythrina corallodendron L. flowers and biological evaluation of the isolated compounds for their activity as antiprotozoal drugs also evaluation the binding affinity to opioid and cannabinoid receptors as well as the inhibition activity against monoamine oxidase (MAO) enzymes. Method: The 70% alcoholic extract was subjected to successive column chromatographic (CC) separations using silica gel normal phase, reversed phase RP-18, Diaion HP-20, and Sephadex LH-20. The structural elucidation of the isolated compounds was achieved using HR-ESI-MS, UV, 1D and 2D NMR spectroscopic analysis. The isolated compounds were screened in vitro for the binding affinity to opioid and cannabinoid receptors using receptor binding assay as well as the inhibition activity against MAO enzymes using kynuramine deamination assay, while their antiprotozoal activity was evaluatedusing parasitelactate dehydrogenase serum assay (pLDH). Results: The phytochemical evaluation of the alcoholic extract of E.corallodendron flowers, afforded the isolation of an indole alkaloid Hypaphorine 1, a new flavonoid glucoside; Kaempferol-3-O-α-sophoroside 2 and three known flavonoid C-glycosides vis;, Neoschaftoside 3, Isoschaftoside 4 and Vicenin-II 5. Compounds 3 and 4 are reported for the first time from genus Erythrina. Compounds 4 and 5 showed significant antimalarial activity both with IC50 value 1.7µg/mL against (D6) strain and with IC50 1.4 and 1.1 µg/mL against (W2) strain, respectively. Compound 3 showed selective inhibition to MAO-B with IC50 value of 32.08 µM and selective index (SI) > 3.12. Conclusion: The significant antiplasmodial activity of compounds 4 and 5 correlated the known antimalarial activity of different Erythrina species to flavonoid C-glycosides, Also compounds 3 and 4 are position isomers but exhibited different response against MAO-B which gives indication about the selectivity pattern of the flavonoid C-glycosides with MAO-B receptor subtype.

Objectives: This study aimed to compare two Livistona species; Livistona decipiens Becc and Livistona australis Mart for their phenolic and carbohydrate contents and for their protective activity against ulcerative colitis. Methods: A high performance liquid chromatographic (HPLC) technique with inline connected to photo diode array detector (DAD) and electro array (EA) used for detection of the polyphenolic contents. Also HPLC with refractive index detection (HPLC-RI) was used to determine and to quantify carbohydrate contents before and after partial acid hydrolysis, using 0.2 N H2SO4, for 3 h at 100°C, for each of the defatted methanol extract concentrate. Protective activity against ulcerative colitis was evaluated by acetic acid inducing-ulcers method for both methanol extracts of both species. Results: Both investigated Livistona species are rich in polyphenolic constituents, showing a great similarity. The major flavonoid compound in both species was luteolin-6-C-arabinoside-8-C-glucoside and the major aglycone was acacetin, while the major phenolic acid in both species was ellagic acid. However there was a difference in the carbohydrate content between the two species, the main sugars, before hydrolysis, in L. decipiens were arabinose, mannose and sucrose, while the main sugars in L. australis were glucose, fructose and maltose. However, stachyose was the major polysaccharide obtained after partial acid hydrolysis. L. australis showed protective activity against ulcerative colitis in lower dose 500 mg/kg when compared to L. decipiens that only showed effectiveness at a doubled dose 1000 mg/kg. Conclusion: Both Livistona species have potential medicinal value being rich in polyphenolic and polysaccharide contents and having protective activity against ulcerative colitis.
