用胶束毛细管电泳法(MECC)测定牡丹皮、白芍、赤芍及其不同炮制品的牡丹酚、芍药甙的含量,以30mmol/L.磷酸盐缓冲溶液(NaH_2PO_4-Na_2HPO_4)中含20mmol/L+二烷基硫酸钠(SDS)的表面活性剂作电解质,pH=6.85,于254nm紫外检测.实验结果线性关系良好(r>0.998),塔板数达到4.6×10~4.
The contents of paeonol and paeoniflorin of Cortex Moutan, Radix Paeoniae Alba, Radix Paeoniae Alba and its processed products were determined by micellar capillary electrophoresis (MECC). The content of paeoniflorin and paeoniflorin in the solution of 30 mmol / L phosphate buffer solution (NaH 2 PO 4 -H 2 HPO 4) L + sodium dialkyl sulfate (SDS) as electrolyte, pH = 6.85, UV detection at 254nm.The experimental results showed good linearity (r> 0.998) and the number of plates reached 4.6 × 10 ~ 4.
