Abstract:: To compare the difference in content of flavonoids in diaphragma kernel pellicle and shell of Juglans regia from different regions，and determine the content of Luteolin-7-O-β-D-glucoside in three different parts of walnut.HPLC was used to establish content of Luteolin-7-O-β-D-glucoside in three extracts，and colorimetry were used to compare the content of total flavonoids in the samples.The results showed that，the content of Luteolin-7-O-β-D-glucoside in different producing area of walnut was Changzhi>Hotan>Akesu>Tarim>Dali>Qinling，the content of total flavonoids：Dali>Qinling>Hotan>Tarim>Changzhi>Akesu.The content of Luteolin-7-O-β-D-glucoside in different parts of walnut：kernel pellicle>shell>diaphragma.The content of total flavonoids：shell>kernel pellicle>diaphragma.There were some differences of contents of total flavonoids in different regions，the walnuts of Shanxi content of Luteolin-7-O-β-D-glucoside was generally higher than other regions，but the content of total flavonoids was the least.The walnuts of Yunnan content of total flavonoids was higher than other regions，but the Luteolin-7-O-β-D-glucoside was less.Kernel pellicle might had similar pharmacological activity as diaphragma of Juglans regia，because it contained higher flavonoids and had good medicinal value as well.
