Abstract

|
This study was carried out to obtain the basic information that can be used to index arrowroots (Pueraria species) in fourteen regions of China and Korea. The puerarin content in various arrowroots produced in the different areas were quantitatively analysed by HPLC. The average of puerarin content of the ’’Galgeun’’ (Pueraria lobata) was higher than that of the ’’Bungalgeun’’(Pueraria thomsonii) produced in China and Korea. As a result, the order of the puerarin content was 1) Korean puerariae radix (P. lobata, 0.609%), 2) Chinese puerariae radix (P. lobata, 0.546%), 3) Chinese puerariae radix (P. thomsonii, 0.066%). This result showed that the content of puerarin in the ’’Galgeun’’(P. lobata) are about 10 times higher than those of the ’’Bungalgeun’’(P. thomsonii).
