It takes a period of 20 years for the Prunus Africana to grow to 30 meters or more. That is one reason there are only a limited number of Prunus Africana found in Kenya‚ Uganda‚ and the Democratic Republic of Congo. The extraction of pulverized‚ dark bark of Prunus Africana is the reason for high demand on these trees for production of drugs for prostate issues. The Prunus Africana is currently being harvested out of eastern highlands of Kenya in the Aberdares Mountains

isolated from tea leaves. This was done through solid-liquid extraction followed by multiple liquid-liquid extraction. Then crude material obtained was then purified by sublimation. The isolated caffeine was subjected to thin layer chromatography (TLC) together with a standard caffeine. The Rf value obtained for both isolated caffeine and standard caffeine was 0.24. Keywords: solid-liquid extraction‚ multiple liquid-liquid extraction‚ sublimation‚ thin layer chromatography‚ percent caffeine

Acme Minerals Extraction Company A long time ago‚ work used to be assigned only to one person and that person was in charge of doing only that task. Then‚ with the new technology innovations‚ we start seeing how companies started to trained some employees to be what they usually called “multi-tasking employees”. Since technology kept changing and became more advanced companies realized that having “multi-tasking employees” was not enough to satisfy the market demands and the production problems

ABSTRACT The extraction of pectin from orange peels has been studied at different sample to solvent ratios‚ different PHs and with different extraction techniques using water. The amount of pectin extracted reduces as the PH increased. This research work is been carried out in order to determine the process condition that will result in high yield of pectin and residual oil extracted from orange peels using the methanol pre-treatment to extract orange peel oil and hydrochloric acid for pectin extraction

Extraction of DNA from Cheek Cells Gene Smith February 29th 2013 INTRODUCTION DNA‚ deoxyribonucleic acid‚ is the genetic material of every living organism and is found in the nucleus of eukaryotic cells. DNA is often called the ‘blueprint for life’ because it contains the necessary information to carry out all the living processes of the cell (1).The purpose of this lab was to extract DNA from human cheek cells. The isolated DNA could be used inmapping or sequencing‚ PCR‚ crime scene investigation

lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic acid derived from

Isolation of Acetyleugenol (Clove Oil) from Cloves Purpose In this experiment‚ you will obtain the essential oil from cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally‚ you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation‚ which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils‚ but
