摘要
Contents of rutin and catechin in leaves and under-ground part of Potentilla fragarioides L.in spring and autumn were determined by HPLC technology.The results show that in spring,rutin content in leaves and under-ground part of P.fragarioides is 1.670 3 and 0.054 4 mg·g-1,and catechin content is 0.263 5 and 0.723 5 mg·g-1,respectively.In autumn,rutin content is 0.586 9 and 0.010 7 mg·g-1,and catechin content is 0.784 3 and 0.366 4 mg·g-1,respectively.The rutin content in leaves is the highest in spring,and catechin content in leaves is the highest in autumn.Therefore,collecting leaves in spring is suitable for taking rutin as a purpose,while collecting leaves in autumn is suitable for taking catechin as a purpose.
