Mulberroside A, morusin, and kuwanon G in Mori Cortex were qualitatively determined by thin layer chromatography (TLC), and the content of moisture, total ash, acid insoluble ash and extract in Mori Cortex from different origins were determined according to the methods in Chinese Pharmacopoeia of 2015 edition; in addition, the content of mulberroside A was determined by high performance liquid chromatography (HPLC). The results showed that the spots of mulberroside A, morusin, and kuwanon G were clear and distinctive. The quality standard (by mass fraction) of Mori Cortex medicinal materials is suggested: moisture should be less than 13%, total ash within 9%, acid insoluble ash no more than 2.5%, water soluble extract obtained by hot dip method no less than 25%, mulberroside A calculated on dried sample no less than 0.91%.

Key words: Mori Cortex, medicinal quality, quality standard, mulberroside A
