hi, netters,
  I've a friend, who studies plant chemistry. He had extracted some unknown 
compounts from one plant, but only 5mg. He can't isolate it by traditional way. Can such small amounts of compounts be isolated on gel(agrose or PAGE?)?
the compount he wants to isolate has no color, followed by another which shows yellow when running on silical gel. 
  any help will be appreciated.
