Extraction of Caffeine from Lipton® Tea Leaves Nathaniel Camangon*‚ Kaila Bumagat‚ Franz Mari Burgos‚ Remigio Callanta Department of Chemistry‚ College of Science‚ University of Santo Tomas‚ Manila‚ Philippines Abstract This experiment mainly focuses on the extraction of pure caffeine by multiple extraction from commercially acquired tea leaves and determining its purity by melting point determination. A 0.02% yield of pure caffeine was obtained from 10.4978g of tea leaves (4 tea bags).

Strawberry DNA lab Extraction Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments. Background information: The long thick fibers of DNA store the information for the function of the chemistry

benzoic acid and a neutral compound (triphenylmethanol or 1‚2‚4‚5-tetrachlorobenzene) into its components by extraction and also to get the melting point. THEORY: Extraction is a process of transferring a solute from one solvent to another. In this experiment‚ a mixture of benzoic acid and a neutral compound (triphenylmethanol or 1‚2‚4‚5-tetrachlorobenzene) into its components by extraction. The mixture is dissolved in diethyl ether (common name is ether). Both components are soluble in this solvent

cataracts. N-acetylcarnosine eye drops is topical non-surgical treatment of cataracts‚ which can improve transmissivity and reduce glare sensitivity. The most common types of surgical treatments include intracapsular cataract extraction (ICCE)‚ Extracapsular cataract extraction (ECCE) and phacoemulsification (Phaco). Surgical removal is more effective for stopping cataract formation. Progression of cataracts can be slowed by avoiding large amounts of ultraviolet light‚ not smoking‚ and following

strawberry or kiwi fruit? Introduction: In the experiment we were inspecting the amount of genetic materials in fruits with different numbers of chromosomes. In the experiment‚ we mashed up a strawberry/kiwi fruit (See appendix 1 figure 2) added extraction butter and ethanol to extract the DNA. A chromosome is a long thread-like cluster of genes in the nucleus. DNA (deoxyribonucleic acid)‚ a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes

In this experiment‚ the separation methods were decantation‚ filtration and evaporation and extraction and each is explained below: Decantation‚ this is the separation of liquid from a solid by careful pouring the supernatant liquid from the holding vessel without disturbing the solid at the bottom of the container. Filtration‚ Filtration is a

to land degradation large sums of money are payed towards the environment. # Bayer process- it is the conversion of bauxite into alumina which needs heaps of amounts of chemicals such as‚ sodium hydroxide‚ which creates additional costs to the extraction. # Waste – created waste is expensive to get rid of and dispose example‚ Fe2O3 is formed in the refining process and it is transported to ponds in order to dispose it there. # 10 tonnes of bauxite are required to produce 1 tonne of aluminium

systems. • To achieve an effective data migration procedure‚ data on the old system is mapped to the new system providing a design for data extraction and data loading. • The design relates old data formats to the new system’s formats and requirements. Programmatic data migration may involve many phases but it minimally includes data extraction where data is read from the old system and data loading where data is written to the new system. • After loading into the new system‚ results
