摘要:目的 建立并比较续断饮片、水煎剂、配方颗粒的HPLC指纹图谱。方法 采用Wondasil C18色谱柱(4.6 mm×250 mm,5 ?m),以乙腈-0.1%磷酸溶液为流动相进行梯度洗脱,流速1.0 mL/min,检测波长212 nm,柱温30 ℃。结果 分别建立了12批续断饮片、水煎剂、配方颗粒的指纹图谱。12批续断配方颗粒HPLC指纹图谱的14个共有峰均能在水煎剂中得到追踪,有13个共有峰可在饮片中得到追踪,并指认出川续断皂苷Ⅵ、绿原酸2个成分。结论 建立的HPLC指纹图谱方法重复性好、稳定。续断饮片、水煎剂、配方颗粒所含化学成分组成基本相同。

Abstract: Objective To establish and compare HPLC fingerprint chromatograms of Dipsaci Radix decoction pieces, aqueous decoction and formula granules. Methods The HPLC analysis was carried out in Wondasil C18 column (4.6 mm × 250 mm, 5 ?m) with a mobile phase of acetonitrile-0.1% phosphoric acid by gradient elution. The flow rate was 1.0 mL/min; the detection wavelength was set at 212 nm; the column temperature was kept at 30 ℃. Results The fingerprint chromatograms from 12 batches of Dipsaci Radix decoction pieces, aqueous decoction and formula granules were established respectively. 14 common peaks in the fingerprint chromatogram in the formula granules could be tracked in the aqueous decoction, and 13 common peaks in the fingerprint chromatogram could be tracked in the decoction pieces. 2 chemical compounds were identified, such as asperosaponin Ⅵ and chlorogenic acid. Conclusion The method of HPLC fingerprint chromatograms is stable and with good repeatability. Dipsaci Radix decoction pieces, aqueous decoction and formula granules are basically the same chemical composition.

续断为川续断科植物川续断Dipsacus asper Wall. ex Henry的干燥根,《神农本草经》列为上品。续断性微温,味苦、辛,归肝、肾经,具有补肝肾、强筋骨、续折伤、止崩漏功效,用于肝肾不足、腰膝酸软、风湿痹痛、跌仆损伤、筋伤骨折、崩漏、胎漏等,是妇科和骨伤科常用中药,主要含有三萜皂苷、生物碱、

环烯醚萜类、挥发油类等成分[1-2]。

续断配方颗粒是以符合炮制规范的续断饮片为原料,经现代提取、浓缩、干燥、制粒等制剂工艺加工而成。配方颗粒突破了传统中药饮片煎煮的应用形式,具有免煎易服、作用迅速、成分完全、安全卫生、携带方便等优点,可成为替代传统中药饮片在临床上使用的新剂型,并越来越被广大患者所接受[3-4]。由于续断在传统方剂中多以汤剂入药,因此,有必要对续断饮片、水煎剂、配方颗粒三者之间化学成分组成进行比较。……
