Extraction, Isolation and Characterization of Bioactive ...

2010-10-2 · The extraction of hydrophilic compounds uses polar solvents such as methanol, ethanol or ethyl-acetate. For extraction of more lipophilic compounds, dichloromethane or a mixture of dichloromethane/methanol in ratio of 1:1 are used. In some instances, extraction with hexane is used to remove chlorophyll (Cos et al., 2006).

Solid Phase Extraction (SPE)

Solid phase extraction (SPE) is a technique used for rapid, selective sample preparation and purification prior to chromatographic analysis (e.g. HPLC, GC, TLC). SPE is used to exchange sample matrices, concentrate analytes, and remove interferences and contaminants to improve data and protect the analytical column.

Liquid-Liquid Extraction

Liquid/liquid extraction (LLE) is based on the partition of an analyte between two immiscible phases, one being the serum or the urine. It is often performed at a pH where the analyte is non-ionized to facilitate its migration into the organic phase. This inexpensive and easy to implement method is still widely used.

RNA Extraction Without A Kit

2020-3-24 · RNA extraction methods evolved into a simple protocol still used today. There are many alternative methods for isolating DNA without a kit. However, that isn''t the case for RNA extraction and purification. There is one simple method that works, and variations to that method. A major hurdle to developing protocols to isolate RNA was that ...
