| Abstract: | This paper explores an optimum extration technology of gentiopicroside from gentiana macrophylla pall.By using gentiopicroside as the index,the effects of solvent amount,extraction time,extraction degree and extraction temperature on extraction technology are evaluated by orthogonal design method.The superior condition is as follows: 15 mL water,40 minutes,two times extraction and at 40 ℃.The optimum extraction process is proved stable and accurate by verificated test,and it is suitable for extraction of gentiopicroside from gentiana macrophylla pall. |
