Who can give me the procedures in plant extraction?

Question

please help

Answer 1

What are you trying to extract?  The solvents used will depend on the compounds wanted.  For instance, a room temperature ethanol extraction will get most of the flavonoids.  Enzymes are typically extracted with aqueous buffers, and with higher plants you usually have to add protective agents like BSA and mercaptoethanol or dithiothreitol.  Etc.
