Simultaneous Quantification of Ibuprofen and Paracetamol in Tablet Formulations Using Transmission Fourier Transform Infrared Spectroscopy

引用

American Journal of Analytical Chemistry 2012年第8期3卷 503-511页

作者： Muhammad Ali Mallah Syed Tufail Hussain Sherazi sarfaraz ahmed mahesar Abdul Rauf Khaskheli National Center of Excellence in Analytical Chemistry University of Sindh Jamshoro Pakistan

A very simple, non-destructive, inexpensive and green strategy was applied for the simultaneous determination of ibu-profen (IBP) and paracetamol (PC) using transmission Fourier Transform Infrared (FTIR) spectroscopy in tablet formulations for routine quality control laboratories. For the determination of the active pharmaceutical ingredients (API), KBr pellets containing known amount of standards and samples were used for acquisition of the FTIR spectra. The partial least squares (PLS) calibration model was developed using the spectral region from 1781 - 1683 cm-1 for IBP and 1630 - 1530 cm-1 for PC. The excellent coefficients of determination (R2), 0.9999 and 0.9998 were achieved for IBP and PC, respectively. The accuracy of calibration model was also verified through root mean square error of cross validation (RMSECV) which was found to be 0.064. This work clearly shows the capability of transmission FTIR spectroscopy for assessment of exact quantity of API to control the quality of finished products as well as during processing in pharmaceutical industries without involvement of any solvent.

镉是中国最重要的环境污染物之一,它对人类和其他动物有一定的毒性。目前,中国已经开发出许多方法来修复镉污染的土壤,其中植物修复方法是最有前景的方法之一。本研究,选择了三个快速生长的杨树:青杨(Populus cathayana),北京4号杨(Populus beijingenesis 4)和赤峰杨(Populus chifeng)为研究对象,以筛选适合的树木进行镉污染修复为目的。我们比较了三种杨树的生物量、镉含量、转运系数(T)、容忍系数(T)及生物富集因子(BCF)。此外,我们还研究了镉胁迫下3种杨树的叶片超微结构、光合活性和抗氧化活性。研究表明,与对照相比,镉胁迫下所有植物的生物量、叶绿素含量和光合活性均较低,抗氧化活性较高。相比之下,青杨(***)受镉影响较小,生物量较多,光合速率(A),蒸腾速率(E)和叶绿素含量较高,而赤峰杨(***)和北京4号杨(***4)生物量较少,A、E和叶绿素含量较低。此外,***与*** 4和***相比,具有更高的T和T,并且与***相比,具有更高的BCF。研究发现*** 4具有最高的BCF,这可能是*** 4比其他两个物种具有更多镉中毒症状的原因。透射电子显微镜(TEM)结果显示*** 4的亚细胞结构受到了较严重的破坏,尤其是类囊体结构和叶绿体膜的破坏,而相比之下,***的亚细胞结构受影响最小,叶绿体几乎不受影响,与其他两个物种相比,叶绿体形状和类囊体结构清晰可见。基于上述研究结果,鉴于在镉胁迫下青杨(***)在三个杨树种中,具有最多的生物量、较强的抗性和较高的镉积累量,因此可以开发为镉修复的候选植物。

The present study aimed to estimate the occurrence of Iron Deficiency anemia (IDA) in school and college going students (aged 11 - 18 years). Anemia is the most public health problem in school age children. It has a wide range of adverse results involving, poor cognitive performance, poor development of infants, preschool and school-aged children. Anemia also causes the impairment of physical capacity, work performance of adolescents and adults, reduction in immune competence and increased morbidity from infections in all age groups. Our study based on 1686 volunteers was randomly selected from different Government High schools and colleges. A Questionnaire was utilized for data collection. BMI was also calculated by dividing weight in kg by the square of height in meters. Hemoglobin (Hb), Hematocrite (Hct), Mean Corpuscular volume (MCV), Mean Corpuscular hemoglobin concentration (MCHC), white blood cell (WBC) and red blood cell was examined using Sysmex kx-21N hemoglobin auto analyzer (Hedwin, 2008). The total percentage of anaemic students (43.1%) and non-anaemic (56.9%) were observed in district Shaheed Benazirabad. The mean Hb level of anaemic students (11.1 ± 4.94) was observed. In males (12.7%) and females (30.4%) anemic was observed. The prevalence of anemia high (16.2%) was observed in the age of 14 - 16 years. The majority of anemic patients (30.2%) belonged to low income group. Area wise prevalence, in rural areas 27.8% and urban areas 15.3% volunteers anaemic was observed. Taluka wise occurrence of anaemia in taluka Sakrand was (14.6%), in taluka Kazi ahmed (15.0%), in taluka Daur (8.0%) and in taluka Nawabshah was (5.5%). Clinically signs and symptoms showed, pale skin 57.7% and weakness 42.3% were observed in school children.
