摘 要 目的:建立同时测定痢必灵片中苦参碱、氧化苦参碱、没食子酸、芍药苷、木香烃内酯和去氢木香内酯含量的方法。方法:
采用反相高效液相色谱法。色谱柱为Agilent ZORBAX SB-C18,流动相为甲醇-0.1%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检
测波长为210 nm(苦参碱、氧化苦参碱)、225 nm(没食子酸、芍药苷、木香烃内酯、去氢木香内酯),柱温为30 ℃,进样量为5 μL。结
果:苦参碱、氧化苦参碱、没食子酸、芍药苷、木香烃内酯和去氢木香内酯检测质量浓度线性范围分别为 0.053~5.28 mg/mL(r=
0.999 8)、0.125~12.54 mg/mL(r=0.999 9)、0.013~1.33 mg/mL(r=0.999 8)、0.169~16.94 mg/mL(r=0.999 9)、0.048~4.77 mg/mL

ABSTRACT OBJECTIVE: To establish a method for simultaneous determination of matrine, oxymatrine, gallic acid,
peoniflorin, costunolide and dehydrocostus lactone in Libiling tablets. METHODS: RP-HPLC method was adopted. The
determination was performed on Agilent ZORBAX SB-C18 column with mobile phase consisted of methanol-0.1% phosphoric acid
(gradient elution)at the flow rate of 1.0 mL/min. The detection wavelengths were 210 nm(matrine,oxymatrine)and 225 nm
(gallic acid,peoniflorin,costunolide,dehydrocostus lactone). The column temperature was set at 30 ℃,and sample size was 5
µL. RESULTS:The linear ranges of matrine,oxymatrine,gallic acid,peoniflorin,costunolide,dehydrocostus lactone were
0.053-5.28 mg/mL(r=0.999 8),0.125-12.54 mg/mL(r=0.999 9),0.013-1.33 mg/mL(r=0.999 8),0.169-16.94 mg/mL(r=

0.999 9),0.048-4.77 mg/mL(r=0.999 8),0.072-7.16 mg/mL(r=0.999 9). The limits of quantitation were 4.08×10 ,4.48×10 ,

(n=6). The recoveries were 98.03%-101.43%(RSD=1.25%,n=6),97.73%-102.26%(RSD=1.96%,n=6),97.18%-101.41%
(RSD=1.98%,n=6),97.45%-102.11%(RSD=1.88%,n=6),96.85%-101.07%(RSD=1.75%,n=6),97.12%-102.64%
(RSD=1.82% ,n=6),respectively. CONCLUSIONS:Established method is simple,stable and rapid,and can be used for
simultaneous determination of 6 components in Libiling tablets.
