ABSTRACT: The majority of natural colourants are of vegetable origin from plant sources –roots, berries, barks, leaves, wood and other organic sources such as fungi and lichens. In the medicinal and food products apart from active constituents there are several other ingredients present which are used for either ethical or technical reasons. Colouring agent is one of them, known as excipients. The discovery of man-made synthetic dye in the mid-19th century triggered a long decline in the large-scale market for natural dyes as practiced by the villagers and tribes. The continuous use of synthetic colours in textile and food industry has been found to be detrimental to human health, also leading to environmental degradation. Biocolours are extracted by the villagers and certain tribes from natural herbs, plants as leaves, fruits (rind or seeds), flowers (petals, stamens), bark or roots, minerals such as prussian blue, red ochre & ultramarine blue and are also of insect origin such as lac, cochineal and kermes. -

It is only recently (the first artificial dye was invented in 1857) that the textile industry has turned to synthetic dyes. Today, many craftspeople are rediscovering the joy of achieving colour through the use of renewable, non-toxic, natural sources. Natural dyes are inviting and satisfying to use. Most are familiar substances that will spark creative ideas and widen your view of the world. Try experimenting. Colour can be coaxed from many different sources. Once the cloth or fibre is prepared for dyeing it will soak up the colour, yielding a range of results from deep jew- el-like tones to dusky heathers and pastels. -
New Facile and Sensitive Methods for the Estimation of Telmisatran Y
J. Curr. Chem. Pharm. Sc.: 4(1), 2014, 30-33 ISSN 2277-2871 NEW FACILE AND SENSITIVE METHODS FOR THE ESTIMATION OF TELMISATRAN Y. KRANTI KUMAR, K. VANITHA PRAKASH* and GUTHI LAVANYA Department of Pharmaceutical Analysis, SSJ College of Pharmacy, V. N. Pally, Gandipet, HYDERABAD – 500075 (A.P.) INDIA (Received : 26.10.2013; Accepted : 03.11.2013) ABSTRACT Two simple, accurate, rapid and sensitive Methods (A and B) have been developed for the estimation of Telmisatran in its pharmaceutical dosage form. The method A is based on the formation of yellow colored chromogen, due to reaction of Telmisatran with Alizarin red dye. The formation of ion association complexes of the drug with dyes in acidic phthalate buffer of pH 2.8 was followed by their extraction in chloroform, which exhibits λmax at 423 nm. The method B is based on the formation of golden yellow colored chromogen due to reaction of Telmisatran with Bromophenol blue dye. The formation of ion association complexes of the drug with dyes in acidic phthalate buffer of pH 2.8 was followed by their extraction in chloroform, which exhibits λmax at 416 nm. The absorbance-concentration plot is linear over the range of 100- 150 mcg/mL for method A and 20-50 mcg/mL for method B. Results of analysis for all the methods were validated statistically and by recovery studies. The proposed methods are precise, accurate, economical and sensitive for the estimation of Telmisatran in bulk drug and in its tablet dosage form. Key words: Telmisatran, Alizarin red, Bromophenol blue. INTRODUCTION Telmisartan is an angiotensin II receptor antagonist used in the management of hypertension. -

Separation of Hydroxyanthraquinones by Chromatography
Separation of hydroxyanthraquinones by chromatography B. RITTICH and M. ŠIMEK* Research Institute of Animal Nutrition, 691 23 Pohořelice Received 6 May 1975 Accepted for publication 25 August 1975 Chromatographic properties of hydroxyanthraquinones have been examined. Good separation was achieved using new solvent systems for paper and thin-layer chromatography on common and impregnated chromatographic support materials. Commercial reagents were analyzed by the newly-developed procedures. Было изучено хроматографическое поведение гидроксиантрахинонов. Хорошее разделение было достигнуто при использовании предложенных новых хроматографических систем: бумажная хроматография смесью уксусной кислоты и воды на простой бумаге или бумаге импрегнированной оливковым мас лом, тонкослойная хроматография на целлюлозе импрегнированной диметилфор- мамидом и на силикагеле без или с импрегнацией щавелевой или борной кислотами. Anthraquinones constitute an important class of organic substances. They are produced industrially as dyes [1] and occur also in natural products [2]. The fact that some hydroxyanthraquinones react with metal cations to give colour chelates has been utilized in analytical chemistry [3]. Anthraquinone and its derivatives can be determined spectrophotometrically [4—6] and by polarography [4]. The determination of anthraquinones is frequently preceded by a chromatographic separation the purpose of which is to prepare a chemically pure substance. For chromatographic separation of anthraquinone derivatives common paper [7—9] and paper impregnated with dimethylformamide or 1-bromonaphthalene has been used [10, 11]. Dyes derived from anthraquinone have also been chromatographed on thin layers of cellulose containing 10% of acetylcellulose [12]. Thin-layer chromatography on silica gel has been applied in the separation of dihydroxyanthraquinones [13], di- and trihydroxycarbox- ylic acids of anthraquinones [14] and anthraquinones occurring in nature [15]. -

ASHNAGAR¹*, N. GHARIB NASERI² and A. SAFARIAN ZADEH¹ ¹School of Pharmacy, Ahwaz Jundi Shapour Univ. of Medical Sciences, Ahwaz (Iran) ²Ahwaz Faculty of Petroleum Engineering, Petroleum University of Technology, Ahwaz (Iran) (Received: March 02, 2007; Accepted: April 03, 2007) ABSTRACT The roots of madder (Rubia tinctorum) are source of anthraquinone dyes with alizarin being the main component. Free alizarin (I) is present in madder root in only small quantities, most of it is present as its glycoside i.e. ruberythric acid(III) On the basis of the importance of alizarin, in this research, it was isolated, purified and its structure was confirmed by various spectra. Maceration of the powdered madder roots in various polar and non-polar solvents, as well as Soxhlet extraction resulted in the formation of a reddish solid material (5.2% and 14.2% yield, respectively). Successive TLC and column chromatography of the solid material on silica gel with methanol as the mobile phase, gave three fractions with Rf = 0.21, 0.48 and 0.68. The fraction with 1 13 Rf = 0.68 was the major one. HNMR, CNMR, IR, UV and Mass spectra of this fraction were taken. On the basis of the results obtained from the spectra, the chemical structure of alizarin was determined and confirmed. Keywords: Alizarin, 1,2-dihydroxy-9,10-anthraquinone, 1,2-dihydroxy-9,10-anthracenedione, Rubia tinctorum, madder roots, ruberythric acid. -

Abstract We aim to use the natural dyeing of textiles from the past as a basis of modern dye natural dyeing of textiles. The natural dyes and methods used in the historical textiles were determined. We adapt these to the recent natural dyes in modern textiles by using different analysis techniques. In this study, the metal thread, dyestuff and technical analysis of historical textiles by micro and nondestructive analysis methods were determined. Historical samples were provided from many museum collection. Optical microscopy for the technical analysis, CIEL*a*b* spectrophotometer/colorimeter for the color measurements, HPLC-PAD for the dyestuff analysis and SEM-EDX for the metal thread analysis were performed. According to the results of this analysis, the fabrics that are made in modern times have the same characteristics as the fabrics analyzed due to the use of the same natural dyes. Keywords: Historical textiles, reproduction, natural dyes, dyestuff analysis, elemental analysis, color measurement, technical analysis. 1. INTRODUCTION Identification of an art object material of cultural heritage had received significant attention, because of its importance for the development of appropriate restoration and conservation strategies. Natural dyes have advantages since their production implies renewable resources causing minimum environmental pollution and has a low risk factor in relation to human health. Some of natural dyes are used by pharmaceutical industry as a basis for drug products and by the food industry [1]. -
