摘要
目的:采用HPLC梯度洗脱法同时测定柴丹解郁颗粒中丹参酮ⅡA和丹酚酸B的含量。方法:用Hypersil-ODS C18色谱柱(150 mm×4.6 mm,5μm);甲醇:水梯度洗脱:0-20 min(35-90:65-10)、20-25 min(90-95:10-5)、25-30min(95:5);柱温:30℃;检测波长:0-20 min 282 nm、20-30 min 270 nm;流速:1.0 mL/min。结果:丹参酮ⅡA、丹酚酸B的线性范围分别是0.014448-0.09632μg(r=0.9999)、0.1986-3.972μg(r=0.9999),平均回收率分别为99.62%(RSD为2.28%)、100.58%(RSD为2.50%)。结论:本方法准确可靠,专属性强,结果稳定,重现性好,可较好的控制柴丹解郁颗粒的质量。
AIM : To determine tanshinone Ⅱ A and salvianolic acid B by HPLC gradient elution. METHODS : HPLC was used with Hypersil-ODS C18 column( 150 mm × 4.6 mm,5 μm). The mobile phase consisted of methanol-water 0 - 20 min (35 - 90:65 - 10 ), 20 - 25 min (90 - 95 : 10 - 5 ), 25 - 30 min ( 95 : 5 ) gradient elution. The flow rate was 1.0 mL/min with column temperature at 30 ℃. The UV detection wavelength was at 286 nm in 0 - 20 min and 270 nm in 20 - 30 min, respectively. RESULTS : The linear range of tanshinone ⅡA and salvianolic acid B were in the range of 0.014 448 - 0. 096 32 ( r = 0. 999 97 ), and 0. 198 6 - 3. 972 μg( r = 0. 999 94), respectively. The average recoveries were 99. 62% ( RSD = 2. 28% ) and 100. 58% ( RSD = 2. 5% ), respectively. CONCLUSION: The method is accurate, sensitive, reproducible, and suitable for the quality control of Chaidan Jieyu Granules.
