摘要
目的:用高效液相色谱法测定铜陵不同土壤生长的同年生凤丹皮中丹皮酚和芍药苷的含量,并比较其质量差异。方法:采用WatersVP—ODS—C18色谱柱(150mm×4.6mm,5μm);丹皮酚含量测定流动相:甲醇-水(60:40),检测波长:274nm,柱温:30℃,流速1.0mL·min-1;芍药苷含量测定流动相:乙腈-0.1%H3PO4(20:80),检测波长:230nm,柱温:30℃,流速:1.0mL·min-1。结果:丹皮酚在1.073—5.365μg,芍药苷在0.593—2.965Ixg均呈良好线性关系,r分别为0.9999,0.9991,丹皮酚平均回收率为99.96%(RSD=0.72%),芍药苷平均回收率为99.03%(RSD=0.49%)。结论:选定的3种土壤生长的凤丹皮的丹皮酚和芍药苷含量均是金沙土〉稻田土〉马钢土。
Objective: Comparison the paeonol and paeoniflorin content of Feng-Moutan Cortex in different growth soil of Tongling by HPLC. Methods: Using the Waters VP-ODS-Clschromatographic column ( 150 mm × 4. 6 mm, 5 μm); mobile phase for paeonol: methanol-water (60:40), detection wavelength: 274 nm, column temperature : 30 ℃, the flow rate : 1.0 mL- min - 1 ; mobile phase for the paeoniflorin : acetonitrile - 0. 1% n3 PO4 (20:80), detection wavelength: 230 nm, column temperature: 30 ℃, the flow rate: 1.0 mL·min-1. Results: Paeonol and paeoniflorin had good linear relationship in 1. 073-5. 365 μg ( r = 0. 999 9 ) and 0. 593-2. 965μg ( r = 0. 999 1 ) respectively. The average recoveriey of paeonol was 99.96% ( RSD = 0.72% ) , of paeoniflorin was 99.03% ( RSD = 0. 49% ). Conclusion: Paeono] and paeoniflorin content from Jinsha growth soil 〉 Daotian growth soil 〉 Magan growth soil.
