This study was carried out in order to characterize the flavor of Pueraria radix-green tea. To make a new tea with good flavor and functional properties, Pueraria radix was mixed with green tea. Volatile flavor compounds of Pueraria radix-green tea were extracted by simultaneous distillations and extraction methods using a Likens and Nickerson's extraction apparatus. The concentrated extract was analyzed and identified by GC and GC-MS. Forty-nine compounds including $\beta$-selinene, $\beta$-caryophyllene, hexanal and nonanal were isolated and identified from Pueraria radix. Sixty-four compounds including nerolidol, linalool, linalool oxide and phenylethyl alcohol were isolated and identified from green tea. Eighty-two compounds including linalool, $\delta$-cadinene, limonene, $\beta$-caryophyllene and $\beta$-ionone were isolated and identified from Pueraria radix-green tea.
