Study On Quality Standard Of Fraxinus Mandshurica Rupr

Fraxinus mandshurica Rupr was Oleaceae Fraxinus plant, it's bark has the effect of anti-inflammation and analgesia,and it is usually used as the succedaneum of the ash brak, its main component is coumarin.The main appraisement index of ash brak drugs is esculin and esculetin,and their difference was very large, at the same time,it was difficult to detect them in the Fraxinus mandshurica Rupr of some habitat, at the present time there are not corresponding standard to judge the quality of the Fraxinus mandshurica Rupr.In this thesis,the content of the Fraxinus mandshurica Rupr were identified by HPLC method, and the quality of the Fraxinus mandshurica Rupr was entirely controlled,so the quality control specification was supplied for the development of the Fraxinus mandshurica Rupr.In this paper, The Mandshurin content of the Fraxinus mandshurica Rupr was studied by HPLC method. The results were shown that the similarity of the three samples was high,so the measure results of HPLC method was steady,and the repeatability was good,at the same time,the instruments was common,the method was simple,fast,credibility,practice and feasible, so the new facility was supplied for the quality controlling of the Fraxinus mandshurica Rupr,and the HPLC method could be used as the quality evaluation and identification of the Fraxinus mandshurica Rupr.
