Pueraria tuberosa known as “Kudzu” is a vulnerable perennial woody liana and native to South–East Asia. The tuber of this plant is used in traditional medicine system and possesses various pharmacological properties due to presence of various Isoflavonoids. The present study has been aimed to create GIS map of P. tuberosa with special reference to South Rajasthan. Analysis of total isoflavonoids content in tuber and its correlation with size and geographical distribution has also been done. HPLC profiling of different sized tuber revealed that palatable tubers are watery and very poor in puerarin (0.3 mg/g DW), diadzin (0.17 mg/g DW) and genistin (0.87 mg/g DW). The biggest tuber (~ 4.5 kg) contained highest amount of Puerarin (100.79 mg/g DW) obtained from one geographical region while the biggest tuber (~ 180 g) from another geographical region contained no detectable puerarin and high diadzin (10.4 mg/g DW). Further germination pattern of seeds revealed that a systematic management practice may increases the survival of seedlings up to 70%.
