摘要 | 采用HPLC法分析了江苏省东海县中药种植场内芍药(Paeonia lactiflora Pall)在9-11月间根中芍药甙含量的动态变化及其他各主产地芍药根中芍药甙含量。结果表明:芍药甙的含量在9-11月间的变化趋势是低→高→低最后趋于平稳,在10月初含量最高;一天中以中午采集时芍药甙含量最高;芍药甙含量与根直径成反比(Y=-1.50X+5.787),即根直径越小,芍药甙含量越高。 |
Abstract | By HPLC method, the dynamic change of paeoniaflorin content in roots of Paeonia lactiflora Pall planted in Donghai County, Jiangsu Province was detected .The results showed that from September to November, the content of paeoniaflorin was from low to high, and then to low, at last it became stable, so the content of paeoniaflorin reached the highest in early October;during a day, it was the highest in the noon .In addition , the content of paeoniaflorin was a negative relation with diameter of P. lactiflora roots( Y =-1 .50X +5 .787) , that is the content of paeoniaflorin increases with decreasing of the diameter of root . |
