提要 采用RP-HPLC测定天乐口服液中橙皮苷的含量,以μ-Bondapak
C18柱(10 μm,4.6 mm×250 mm)为固定相,2%甲醇的乙腈溶液-0.1% 磷酸和0.1%三乙胺的水溶液(20∶80)为流动相进行测定,紫外检测波长284
nm,平均回收率为99.95%,RSD=0.93%(n=6)。 QUANTITATIVE DETERMINATION OF
HESPERIDIN IN Zhan Shiqin Li Kaimin Zhou Shaofen ABSTRACT The content of hesperidin in Tianle oral liquid was determined by
RP-HPLC. Hesperidin was separated by μ-Bondapack C18
colunm(10 μm, 4.6 mm×250 mm).The mobile phase
consisted of 2% methanol acetonitrile-0.1% phosphoric acid and 0.1% triethylamine aqueous
solution(20∶80). The detection was at 284 nm. The
average recovery was 9.95%, RSD=0.93%(n=6). 天乐口服液是由太子参、白术、陈皮等10味药材制成的复方制剂,具健脾开胃,消食导滞之功效,用于小儿脾胃虚弱、厌食等症。实验采用RP-HPLC测定天乐口服液中橙皮苷含量,操作简便,被测组分分离完全,测定结果准确、可靠。 1 实验部分
