CHAPTER 4 RESULTS AND DISCUSSION 4.1 Percentage yield Fresh leaves of C. nardus with 1 kg portion yielded about 22.57g of aqueous crude extract‚ which was approximately about 2.26% of yield. The result showed that fresh leaves had a higher percentage yield compared to the air-dried leaves‚ it was only 1.3% yield which conducted by Koba et al. (2009) with the similar extraction technique. There were other factors that might affect the percentage yield‚ such as influence of the harvest place

This experiment was designed in order to extract caffeine from coffee grounds. In order to do this‚ filtration and extraction techniques with solvents such as calcium carbonate‚ magnesium sulfate‚ and dichloromethane were used1. Decaffeination is something that’s used around the world‚ and there is much discussion on the different methods that can be used. In this case‚ using solvents and heat was the preferred method in order to extract the caffeine. Decaffeination is often used to in order to prevent

Cleveland‚ OH. November 30‚ 2012 Summary The purpose of this report is to determine why we should lease computer equipment as opposed to purchasing computer equipment. Leasing computers can save this organization revenue by not having to have an on-site IT Department for any hardware or software issues that develop. Any technological advances that develop can be upgraded to stay current with technology. This report will also look at the total cost of ownership as compared to leasing computer

higher-boiling compounds behind in the mixture. By isolating the vapor produced at different temperatures and condensing them (i.e.‚ converting gases to liquids)‚ you can effectively separate and purify compounds based on their boiling points. While there are multiple factors that contribute to the efficiency of distillation‚ the first‚ most obvious is the boiling points of the compounds themselves. If one compound is significantly more volatile than another (∆bp > 40 C)‚ then the compounds can be effectively
