摘要:目的 优选银槐解毒颗粒提取工艺。方法 在单因素试验基础上,采用响应面法考察提取时间、料液比、浸泡时间对银槐解毒颗粒中绿原酸、总黄酮提取方法的影响。采用HPLC同时测定绿原酸、总黄酮的含量,流动相为乙腈(A)-0.1%磷酸水(B),梯度洗脱(0~20 min,13%A;20~30 min,13%~18%A;30~55 min,18%~20%A;55~65 min,20%~23%A),绿原酸和黄酮类成分的检测波长分别为327、256 nm。结果 最佳提取工艺条件为浸泡时间60 min,加12倍量水,提取130 min,提取2次。绿原酸、芦丁、黄芩苷平均浓度分别为51.497、68.872、25.763 ?g/g,平均浸膏得率为33.105%。结论 优化后的提取工藝稳定可行,可为银槐解毒颗粒后续生产提供数据支持。

Abstract: Objective To optimize extraction process of Yinhuai Jiedu Granula. Methods On the basis of single factor experiments, effects of soaking time, solvent dosage and extracting time on contents of chlorogenic acid and total flavonoids were investigated by response surface methodology. HPLC was used to determine contents of chlorogenie acid and total flavonoids with mobile phase of acetonitrile-0.1% phosphoric acid for gradient elution (0–20 min, 13%A; 20–30 min, 13%–18%A; 30–55 min, 18%–20%A; 55–65 min, 20%–23%A) and detection wavelengthes of 327 nm and 256 nm for chlorogenic acid and total flavonoids respectively. Results Optimal extraction process was as following: soaked 60 minutes and extracted twice with 12 times the amount of water per time of 130 minutes. Concentrations of chlorogenic acid, rutin and baicalin were 51.497, 68.872, 25.763 ?g/g respectively. The average extract yield was 33.105%. Conclusion The optimized extraction process is feasible and stable, which can provide data support for the further research on Yinhuaijiedu granula.
