This paper aimed at studying the physical and chemical properties, general examination and contents of someeffective components of Erratum Mongolia, and to provide scientific basis for the establishment of the quality standard ofvenerates Mongolia. The physical and chemical properties of venerates were identified by microscope and thin layerchromatography, and the general examination of venerates was studied with reference to the appendix of the 2010 editionof People's Republic of China Pharmacopoeia, and the main characteristic components and the active components inErratum were analyzed by HPLC. The content was analyzed and compared. The characters and microscopic identificationconfirmed that all the 7 batches of samples were venerates. The TLC identification was used as the control product ofhermitage, Erratum and restorative. The test products showed the same color spots in the corresponding position of thecontrol products. The spots were clear and the separation degree was good; the water and extracts of the different batch ofvenerates were examined by general terms. The content of ash in the Erratum collected from different regions was notsignificantly different (5.74-6.98％) . The content of the main active ingredients (hermitage) in Erratum from differentareas of the same plant is compared for the first time. The method is simple and reproducible. It provides a scientificbasis for improving the quality standard of Erratum Mongolia, the safe and rational application and the furtherdevelopment and production.
