Endowed with a variety of agro-climatic conditions, India is a virtual herbarium of the world. The importance of medicinal and aromatic plants has been emphasized from time to time. It is accepted that the drug of natural origin shall play an important role in health care, particularly in the rural areas of India. India is having a high knowledge of phototherapy from Ayurveda, and still, hundreds of potent drugs are yet to be evaluated scientifically. Keeping this in view, we reviewed one of the potential trees whose leaves and other parts also have a potent traditional application, but it has not been much studied. </p> 2020-06-13T00:00:00+00:00 Copyright (c) 2020 Ghumare Pramila, Dattatraya Jirekar, Shailendrasingh Thakur, Ramesh Ware, Mazahar Farooqui https://purkh.com/index.php/tochem/article/view/797 New Chromogenic Spray Reagent for TLC Detection and Identification of Organophosphrous Insecticide Monocrotophos in Biological Material. 2020-04-25T14:29:58+00:00 U D Pawar rkpardeshiudp@gmail.com C D Pawar rkpardeshiudp@gmail.com B S Dhobal rkpardeshiudp@gmail.com R K Pardeshi rkpardeshiudp@gmail.com <p>Monocrotophos is a member of Organophosphate insecticide.

M.Pathan abdu.alkhawlany@gmail.com Ifra Fatema abdu.alkhawlany@gmail.com <p>The study of attenuation coefficients of various materials is an important part of research in radiation physics, chemistry, human health, and agriculture. In addition, the linear and mass absorption coefficients have a major role in the estimation of absorbed dose use in the medical and radiation dosimetry. In this paper, the liner and mass absorption coefficients, half-value layer, tenth value layer, and mean free path have been determined by performing the experiment of gamma irradiation on soil samples for gamma energy 0.360 MeV using NaI(Tl) detector. Furthermore, the physicochemical properties of the investigated soil samples were measured using standard methods to assess soil quality. Samples of soil were collected from different sites of Aurangabad-India and prepared using standard techniques. The mass attenuation coefficient decreases exponentially with increasing density and confirms the interaction of gamma-ray with different soil samples of various components. The mass absorption coefficient depends on sample density, gamma energy, the chemical composition of the soil, and its physical properties. The experimentally measured values are in good agreement which validates the gamma absorption law. Generally, the absorption coefficients of gamma-ray measured in this study can be used for the determination of gamma-ray interaction with any soil samples. The study has practical importance to know the nature of the soil to be used in agriculture and construction purposes.</p> 2020-06-13T00:00:00+00:00 Copyright (c) 2020 Abdu Hamoud Al-khawlany, J.

The industries manufacturing dyes generate a large volume of water. Wastewater containing dyes in most of the cases is discharged into water bodies without any treatment or impartial treatment. This hampers not only flora and fauna of the aquatic ecosystem but showed adverse effects on human beings. Existing physical and chemical methods have their advantages and disadvantages. Biodegradation of dyes finds an eco- friendly process. In the present study, <em>Micrococcus glutamicus</em> NCIM 2168 was used for decolourization of the dye Direct Red 81. The isolate decolourized 98.54% of the dye at pH 6 and 28°C in 9 hours. Degradation of the dye was confirmed by the change in λ<sub>max </sub>of the decolorized sample. Confirmation of the degradation was done by HPLC and GCMS studies. Degradation was brought about by Oxidoreductases. Toxicity studies revealed nontoxic nature of the product. The culture was found to decolourise mixture of five dyes. Hence, the selected bacterial culture can be successfully used for the treatment of dye containing wastewater</p> 2020-06-13T00:00:00+00:00 Copyright (c) 2020 https://purkh.com/index.php/tochem/article/view/745 Cement Pastes Containing Polypropylene Fibers - Part I: Physical, Chemical and Mechanical Properties 2020-04-17T08:42:10+00:00 H.H.M. Darweesh hassandarweesh2000@yahoo.com <p>The influence of polypropylene fibers (PPF) addition on the physical, chemical, and mechanical properties of Portland cement pastes (OPC) was clearly evaluated. Results showed that as the PPF content increased, the water of consistency (WC) decreased, while the setting times (IST and FST) increased due to the presence of the water reducing mineral admixture (PPF). The Chemically-bound water content (BWn), bulk density (BD), and compressive strength (CS) improved and enhanced up to 0.6 wt. % PPF content, and then decreased onward at all curing times up till 90 days, while the apparent porosity shortened and then enhanced. Above 0.6 wt. % PPF content, all properties were adversely affected. The free lime content (FLn) of the OPC (PP0) increased continuously up till 90 days but decreased with PPF content at all curing ages and with all mixes (PP1-PP7).</p> 2020-06-13T00:00:00+00:00 Copyright (c) 2020 H.H.M.

Nikalje annapratimanikalje@gmail.com Ramesh Gadikar ragadikar2@gmail.com <p>A new simple, precise, and accurate, high-performance thin-layer chromatography method was developed for the simultaneous determination of Atenolol and Chlorthalidone in tablet dosage forms. In this method, TLC aluminum plates pre-coated with silica gel 60 F254used as the stationary phase. The mobile phase consisting of Methylene Chloride: methanol: Ammonia solution 25%, in the ratio of 8.8:1.3:0.1 v/v is used. The densitometry evaluation was done at wavelength 266 nm using Camag scanner III. The developed method shows a well resolution between two peaks Atenolol and Chlorthalidone with Rf values 0.115 (±0.03) and 0.458(±0.03), respectively. The proposed method was validated as per International Conference on Harmonization (ICH) guidelines for parameters such as specificity, precision, accuracy, linearity, and ruggedness and reported the values. The linear regression analysis shows that the correlation coefficient R2 value for Atenolol is 0.999 and 0.997, respectively. The mean percentage recovery values obtained for Atenolol is 101.4 and for Chlorthalidone is 98.4. The statistical analysis shows that this method is suitable for routine analysis for quantification of Atenolol and Chlorthalidone in single or combined dosage forms of formulations.</p> 2020-06-13T00:00:00+00:00 Copyright (c) 2020 Anna Pratima G.

Kayande Drkayande@gmail.com Mazahar Farooqui Drkayande@gmail.com Parag Deshmukh Drkayande@gmail.com <p>The preference of Prefilled syringes is increased over all the vials as container closure systems for liquid injections, when facilitated or self-administration is required.However, prefilled syringes are more complex compared to container closure system(CCS) consisting of vial, rubber stopper and flip off. Container closure integrity assurance and verification has been a specific challenge for prefilled syringes as they feature several sealing areas. A comprehensive understanding of the container closure system is necessary for an appropriate container closure integrity assessment as well as for packagingdevelopment and qualification.</p> <p>Method for the measurement ofcontainer closure integrity(CCI) of prefilled syringes using fluorescence spectrophotometry was developed and validated with a spectroflurometer.Methylene blue solution was initially evaluated as the fluorophore ina syringe with excitation at 605 nm and emission at 678 nm, which generated a limit of detection of 0.06µg/mL. Furtherstudies were conducted using Rhodamine 123, a dye with stronger fluorescence. Using 482 nm excitation and 527 nmemission, the dye in the syringe could be easily detected at levels as low as 0.001 µg/mL. The relative standard deviationfor sixmeasurements of three different sample with different concentration was less than 2.8%. A number of operational parameters were optimized, including the photomultiplier tube voltage, excitation, andemission slit widths. The specificity of container closure integrity was checked by using marketed drug products sample,which showed no interference to the rhodamine detection. Results obtained from this study demonstrated that usingrhodamine 123 for container closure integrity testing with in syringe fluorescence measurements significantlyenhanced the sensitivity and robustness of the testing and effectively overcame limitations of the traditional methylene bluemethod with visual or UV-visible absorption detection.</p> 2020-06-13T00:00:00+00:00 Copyright (c) 2020 Shripad Deshpande, Deepak D.

By comparing the mass of cerium oxalate caused by the adsorbed Ce<sup>3+</sup>, Sn(OH)<sub>2</sub> and Sn(OH)<sub>4</sub> have the ability to adsorb Ce<sup>3+</sup>, while Sn(OH)<sub>4</sub> has a stronger adsorption capacity of Ce<sup>3+</sup>. However, SnO does not have the ability. The possible mechanism of Sn(OH)<sub>X</sub> adsorption Ce<sup>3+</sup> was further discussed. And the result indicates that the hydroxide can adsorb cations by means of anionic groups on its surface in the solution so that the cations can be enriched on the hydroxide surface.

They are coloured used as a natural pigment. It is one of the most important classes of flavonoids &amp; iso-flavonoids across the whole edible plant kingdom. It is the oldest but remains popular in the 21<sup>st</sup> century due to a large number of replaceable hydrogens that allows a large number of derivatives. They bear excellent quality precursors because of this reason a variety of new heterocyclic compounds were synthesized.

Kelechukwu bierechi@gmail.com Gergely Greta femgreta@uni-miskolc.hu <p>The effects of alloying elements on the mechanical, microstructural, and corrosion properties of Aluminum have been investigated. This investigation was done by fabricating alloys of Aluminum and Magnesium, with magnesium concentrations of 0.0, 0.1, 0.4, 0.8, 1.2, 1.5, and 1.8 weight percent. Subsequently, the mechanical properties of the samples were tested. Optical microstructural examinations were carried out on each of the samples, and the corrosion properties in a 0.2M H<sub>2</sub>SO<sub>4</sub> solution were determined using the coupon testing method. The results obtained show that Magnesium does not just affect the mechanical, microstructural, and corrosion properties of Aluminum, but these properties are also dependent on the relative content of Aluminum and Magnesium. It was observed that 70 (RHB) was the maximum hardness obtained, and it occurs at 0.8 wt% Mg, after which the hardness becomes negatively affected. Magnesium addition was also found to increases the corrosion rate of (1XXX) aluminum in 0.2M H<sub>2</sub>SO<sub>4</sub>.
