So let’s see creative strategies of the campaign 1.First of all‚ obviously‚ a creative communication approach was to hijack the common term “T.L.C.”‚ imbuing it with new meaning “tummy loving care.” 2.Secondly‚ they wanted an iconic brand image as a brand for everyone. They choose nation‘s typical ’girl next door’ who might credibly need a little help to keep their tummies on track to convey the message. 3.Except for various common media usages‚ they also creatively designed posters‚ which

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

on Phytochemicals Research Review: The effect of flavonoids on arterial function Submitted by 06136786 March 12‚ 2013 For HLTH 331 Advanced Nutrition To Dr. Pyke Cardiovascular disease (CVD) is the leading cause of death in developed countries. Diet‚ particularly foods high in antioxidants‚ has been suggested as a preventative mechanism towards reducing the risk of CVD. Compared with other known dietary sources of antioxidants and flavonoids (tea‚ red wine)‚ dark chocolate and other cocoa

Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

was swirled until the greatest amount of each solid was dissolved. Each solution was spotted along a labeled starting line on the silica gel TLC plate. The TLC plate was put into a developing chamber containing 200:1 acetic acid and allowed to developed until the solvent reached almost to the top of the TLC plate‚ which took about 10 minutes. When the TLC plate finished developing‚ I observed the plate under UV light and noticed that the salicylamide was the only spot that fluoresced purple while

As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase

advantages and disadvantages in using a TLC sheet of a different length. For example‚ it becomes a disadvantage if the TLC sheet in this lab was 5 cm shorter. If this were the case‚ then (Sample A) would not have shown up or the second spot of unknown substance #3. Moreover‚ the unknown substance‚ which consists of (Sample A‚ would be incorrectly identified as a pure substance and/or as consisting of only (Sample D). Contrary to using a shorter TLC sheet‚ a longer TLC sheet might allow more substances

Unknown #1 solution was run against standard solutions of individual analgesics. The components of the unknown product were identified by comparing characteristic traits‚ such as Rf‚ fluorescence and iodine staining‚ to those exhibited by the standards.

January 24‚ 2013 TLC Analysis of Analgesic Drugs Introduction: The purpose of this lab was to determine the composition of four different over-the-counter drugs (Anacin‚ Bufferin‚ Excedrin‚ and Tylenol). These compositions were determined by using the method of thin-layer chromatography (TLC) of the four over-the-counter drugs‚ which were then compared to four different components of drugs (acetaminophen‚ aspirin‚ caffeine‚ and salicylamide).
