Practica in Process Engineering II Extraction
In which cases is it a good idea to use extraction? Draw two 3-component-diagrams: One for a system were extraction is not possible, one diagram where extraction should work Discuss the e ect of the slope of tie lines on extraction Hydrodynamics A high speci c surface allows to increase the mass transfer, thus improving the extraction e ciency
A Simple Universal DNA Extraction Procedure Using SDS and
amplifications when using extraction procedure A), similar activity of LING as in the sample without detergents was ob- served, indicating that our decontamina- tion system with UNG works in conjunc- tion with DNA extraction procedure A The DNA extraction procedure de- scribed, based on SDS and proteinase K,
Concept of standardization, extraction and
c Soxhlet extraction: Soxhlet extraction is only required where the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent If the desired compound has a high solubility in a solvent then a simple filtration can be used to separate the compound from the insoluble substance
A SIMPLE AND COST EFFECTIVE ISOLATION AND PURIFICATION
Extraction is an important step involved in the isolation of bioactive compounds from the plants with medicinal value In our study we followed simple soxhlet extraction method to defat Mitragyna speciosa Korth leaves using petroleum ether followed by extraction with chloroform which yielded 7 22 g of crude chloroform extract It was

extraction, and DNA purification The boiling procedure is one of the simplest pro-tocols, and largely used for total DNA extraction from microorganisms (Reischl et al , 2000; Sepp et al , 1994; De Medici et al , 2003) This simple method has evolved through the simplification of previous ap-
