1. , the Olibanum extraction process of effective component is characterized in thatA, elder generation are broken into coarser powder with frankincense powder, add 1~

  • 10 times of amount 60~

    95% organic solvent, lixiviate 1~

    3 time, and lixiviating solution gets extractum after concentrating;

    B, add 1~

    10% sodium bicarbonate solution or 1~

    5% to extractum sodium hydroxide solution in normal temperature and pressure with stir extraction down 1~

    5 time, each 0.5~

    3 hour, after left standstill 1~

    10 hour, the collecting precipitation layer also dissolves with ether;

    C, use 1~

    10% sodium bicarbonate solution, 1~

    5% sodium hydroxide solution gradient elution respectively again, transfer PH=2~

    6 then, ether is reclaimed in reuse ether extraction 1~

    3 time, Olibanum effective component extracts crude product.
