炎可宁片中大黄5种蒽醌类成分的含量测定
摘要
目的:建立同时测定炎可宁片中芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚的含量的高效液相色谱法。方法:色谱柱Kromasil C18(4.6 mm×250 mm
chrysophanol and physcion in Yankening Tablets by HPLC.Method:Using Kromasil C18 column(4.6 mm × 250 mm
5 μm)
the methanol(A)-0.1% phosphoric acid(B)was used as the mobile phase.Using gradient elution
0 ~ 10 min
75% ~ 85% A
10 ~ 20 min
85% ~ 90% A.The flow rate was 1.0 mL /min.The column temperature was 25 ℃ and the detection wavelength was 254 nm.Result:The linearity of this method were for 0.016-0.0960 mg
0.120-0.072 0 μg for rhein
0.016 0-0.096 0 μg for emodin
0.036 4-0.218 4 μg for chrysophanol
0.015 6-0.093 6 μg for physcion.There coveries of aloe-emodin
rhein
emodin
chrysophanol and physcion were 96.6%
97.2%
96.9%
98.1% and 96.2%.RSD were 0.76%(n = 5)
1.35%(n = 5)
1.57%(n = 5)
1.25%(n = 5) and 0.62%(n = 5)
respectively.Conclusion:This method was rapid
accurate and can be used as one kind of Yankening Tablets’quality control method.
