preparation of column chromatography for isolation of plant compounds. how much silica should be packed in glass column for 1 gram of plant extract
I tend to use 2-5% crude extract by weight. For 1 gram crude extract, I would use about 20 g silica, and I would also dry load it.
Thanks for your valuable suggestion,
Sir, if you could explain " 2-5% crude extract by weight."
I want to understand the basics of docking, and also know about all bioinformatics tools which are free of coast and helpfull in in-silico analysis?
