Hello,
      I'm currently working for a company who are looking into the
extraction of artemisin (?) from Artemesia annua.

      I've been able to crystalise a white solid from the crude
extract but am not sure what it is.  Reading the Internet I have
determined that it may be artemisinin or artemisinic acid.

      Does anyone have the melting point for artesinic acid?  Any
other ideas/advice would be most welcome.

      Best wishes,
