TITLE:
摘要: 目的:建立测定妇科再造丸体外溶出度的方法。方法:采用高效液相色谱法测定制剂中黄芩苷和橙皮苷的含量,色谱柱为WondaSil-C18,流动相为0.2%甲酸溶液-乙腈(梯度洗脱),流速为1.0 mL/min,检测波长为280 nm,柱温为30 ℃,进样量为10 μL;采用桨法测定制剂的累积溶出度,溶出介质为磷酸盐缓冲液(pH 6.8),转速为100 r/min,温度为(37±0.5)℃,取样量为2 mL。结果:黄芩苷和橙皮苷检测质量浓度线性范围分别为6.936~23.12 μg/mL(r=0.999 8)、0.620~3.10 μg/mL(r=0.999 0);定量限分别为4.624、0.620 μg/mL,检测限分别为2.312、0.155 μg/mL;精密度、稳定性、重复性试验的RSD均小于2%;加样回收率分别为95.28%~99.22%(RSD=0.97%,n=9)、96.10%~99.84%(RSD=1.98%,n=9)。样品中黄芩苷和橙皮苷10 h时的平均累积溶出度分别为(97.10±0.09)%、(78.50±0.08)%;溶出63.2%所需时间(TD)分别为(1.88±0.12)、(3.26±0.10)h,溶出50%所需时间(T50)分别为(0.88±0.09)、(1.67±0.14)h。结论:该方法操作简便、准确,可用于妇科再造丸的体外溶出度测定。
ABSTRACT: OBJECTIVE: To establish a method for the determination of in vitro dissolution of Fuke zaizao pills. METHODS: HPLC method was adopted to determine the contents of baicalin and hesperidin in preparation. The determination was performed on WondaSil-C18 column with mobile phase consisted of 0.2% formic acid-acetonitrile (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was set at 280 nm, and column temperature was 30 ℃. The sample size was 10 μL. The dissolution of the preparation was determined by paddle method using phosphate buffer solution (pH 6.8) as dissolution medium with rotate speed of 100 r/min,temperature was (37±0.5)℃, sample size was 2 mL. RESULTS: The linear range of baicalin and hesperidin were 6.936-23.12 μg/mL (r=0.999 8) and 0.620-3.10 μg/mL (r=0.999 0), respectively. Limits of quantitation were 4.624, 0.620 μg/mL, limits of detection were 2.312, 0.155 μg/mL, respectively. RSDs of precision, stability and repeatability tests were all lower than 2%; the recoveries were 95.28%-99.22% (RSD=0.97%,n=9) and 96.10%-99.84% (RSD=1.98%,n=9), respectively. The accumulative dissolution rates of baicalin and hesperidin in sample were (97.10±0.09)% and (78.50±0.08)% at 10 h, respectively. TD were (1.88±0.12)、(3.26±0.10)h,T50 were (0.88±0.09)、(1.67±0.14)h, respectively. CONCLUSIONS: The method is simple and accurate, and can be used for the determination of in vitro dissolution of Fuke zaizao pills.
