Studies on the Active Constituents and Their Contents of stem and Leaf of Qianhu by RP-HPLC / 中草药

ABSTRACT

Chemical constituents of the aerial parts of Qianhu were compared with those present in the roots by RP-HPLC. It was found that the constituents in aerial parts of Peucedanum praeruptorum are similar and higher in content than that in the roots. So it is possible that the aerial parts can be used instead of the roots of the plant. But the chemical constituents in the aerial parts and the roots of P. decursivum are quite different, rendering it impossible to use the aerial parts instead of the roots of the plant.
