摘要
目的:建立测定唾液中双黄连有效成分绿原酸、黄芩苷含量的高效液相色谱法。方法:色谱柱:ODS C18柱(250mm×4.6mm,5μm);流动相分别是:甲醇-磷酸盐缓冲液(20:80,pH2.7),甲醇水(55:45,pH3.0);柱温:55,30℃;流速:1.0mL·min^-1;检测波长:274nm。结果:绿原酸、黄芩苷在唾液中最低定量限分别为0.30,0.15mg·L^-1;平均回收率为:93.9%~111.8%和101.3%~104.4%。结论:该方法适用于唾液样品中双黄连有效成分的HPLC分析。取样量小,灵敏度高,操作简便易行,为利用唾液开展双黄连的临床药动学研究提供了方法学基础。
OBJECTIVE To establish a method for determination of chlorogenic acid and baicalin of Shuanghuanglian injection in saliva by HPLC. METHODS Chromatographicy column: ODS C18 Column(250 mm× 4. 6 mm, 5 μm). inobile phase: methanol-phosphate buffer (20:80, pH 2.7). methanol water(55:45, pH 3.0). the temperature at 55 ℃ and 30 ℃, flow rate was 1. 0 mL·min^-1, and detection wave length at 274 nm. RESULTS In saliva, the LOQ of chlorogenic acid and baicalin was 0.3mg·L^-1 and0.15mg·L^-1, theaveragerecoverywas93.9%-111.8% and101.3%- 104.4%. CONCLUSION TheHPLC method could be used simultaneously for determination of effective components of Shuanghuanglian in saliva samples, which is sensitive and simple for small-biological samples analysis. It was suggested that the methodology study may be practiced in clin ical pharmacokinetics of Shuanghuanglian in saliva.
