A method was developed and validated for analysis of Aceclofenac using UV technique with methanol and phosphate buffer 7.4 as solvent. The HPLC analysis was conducted using two mobile phases, that is, “A” as Acetonitrile: Methanol (80:20 v/v) and “B” as Acetonitrile: methanol: NH3 solution (225:50:1 v/v/v). The method was used for assay determination for tablets dosage forms and results were found to be in compliance with official standards. Validation studies were also carried out for both methods. Linearity, LOD, single point calibration, precision and accuracy and % RSD were calculated. Aceclofenac standard was analysed with UV Spectrophotometer in the concentration ranges of 0.5-50 and 0.4-50 mg/L for each solvent and results showed good linearity with R2 = 0.9998 and 0.9999. The method was also specific that verifies the absence of interference at the max of Aceclofenac. UV analysis was precise with % RSD falling within 2% and LOD as 0.5 and 0.4 mg/L for methanol and PBS 7.4, respectively. The tablets of three brands showed assay percentages within specified limits in methanol (109.33, 103.90 and 105.61%) and PBS 7.4 (108.70, 100.69 and 106.60%). In HPLC analysis, mobile phase ‘B’ showed more sharp peaks with lesser HETP and Tf compared to mobile phase ‘A’. The method was checked for reliability and efficiency for assay and some of the parameters like height efficiency to theoretical plates (HETP), tailing factor, peak heights, peak widths along with validation studies (Linearity range 0.1-50 mg/L, specificity, precision, and limit of detection and single point calibration). The more basic mobile phase B using NH3 solution produced more sharp peaks as compared to less basic mobile phase A. \u0000 \u0000 Key words:  Aceclofenac, UV-Visible spectrophotometry, high performance liquid chromatography (HPLC), validation.","PeriodicalId":7531,"journal":{"name":"African Journal of Pharmacy and Pharmacology","volume":"14 1","pages":"259-277"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5897/ajpp2020.5163","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45816169","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}

For the treatment of Sprue syndrome, a very well-known ayurvedic preparation named Kutajarista (KTJ) is used in the south Asian region. This study aimed to detect the impact of chronic administration of KTJ on hematological parameters. The experimental animals were subdivided into two groups. A high dose (50 mL/kg) of body weight was given to the first group for 42 days and the second group which was considered as the control group was treated with normal water for the same period. There was a remarkable reduction [10.37%, p=0.092] in the total numbers of red blood cells (RBC). A prominent decrease [10.75%. p=0.097] is also observed in the hemoglobin content of the blood. There was a noticeable [11.05%, p=0.077] decrease in the hematocrit level of the blood and a very high [64.35%, p=0.19] increase in the number of white blood cell (WBC) count of the male Sprague-Dawley rat. A remarkably high increase was observed in the absolute count of Neutrophils (220.161%, p=0.12), Eosinophils (368.75%, p=0.11), Lymphocytes [11.29%, p=0.06], and Monocyte [142.781%, p=0.13] count. Also a prominent [↑ 14.15%, p=0.42] increase in the number of platelet counts was observed. Rat cutaneous tail bleeding time and whole blood clotting time shortening were also observed and the result is statistically prominent. As the result shows a significant change in different hematological parameter it can be summarized that KTJ have potential hemotoxicity at a higher dose.

The current standard therapy using interferons or antiviral agents is not successful in all cases and is associated with severe side effects. Consequently, the development of new medicines for the treatment of HBV is still relevant. This experimental study was therefore performed to assess the anti-hepatitis B virus (HBV) potential of 10 endemic medicinal plants from Socotra Island which represents a distinctive region of Yemen. Socotra Island is renowned for its biodiversity with significant flora with globally important plants. The methanolic extracts of the selected plants were first assessed for cytotoxicity on HepG2.2.15 cells and cytotoxicity concentration (CC50) values were resolved. The methanolic extracts of the plants were additionally examined on HepG2.2.15 cells for anti-HBV potential by examining the inhibition of HBsAg and HBeAg production in the culture supernatants, and calculating their half-maximum inhibitory concentration (IC50) and therapeutic index (TI) values. Out of ten plants only five plants exhibit inhibition of HBsAg production in a dose and time dependent manner. These five plants are Acacia pennivenia, Boswellia discorea, B. socotrana, Hypoestes pubescens and Dracaena cinnabari with IC50 values of 21.15, 24.51, 118.94, 17.65, 20.93 μg/mL, respectively.

The fresh leaves were examined for their macroscopic and microscopic properties. Numerical (quantitative analysis) and phytochemical evaluations were carried out using standard methods. Acute toxicity profile of the plant, including LD 50 was investigated using mice while sub-acute toxicity to determine effects of the plant leaf extract on some major organs was investigated for 30 days in rats. The macroscopic, microscopic and numerical features observed in the leaves of P. guineense could aid in sample identification.

Sub-acute toxicological evaluations at the doses of 250 and 500 mg/kg showed mild congestion in all the target organs, except spleen, where at 500 mg/kg, in addition to mild stromal oedema, there was mild follicular activation and moderate hyperplasia of sinus histiocytes.

In the acute toxicity study, CHN leaf at doses from 24.0 to 120.0 g/kg/day was given to 5 groups of Swiss mice by oral administration (equivalent in humans is 0.2 to 10 g/kg/day).

In sub-chronic toxicity studies, CHN was given orally to 2 groups of Wistar rats at doses of 2.8 and 14 g CHN/kg/day (equivalent in humans is 0.4 and 2 g/kg) for 28 days taking CHN daily.
