目的 建立高效液相色谱法(HPLC)对半夏及其伪品进行指纹图谱分析,以鉴定半夏的真伪。方法 用SB-Aq色谱柱(4.6 mm×250 mm,5 μm),以0.2%磷酸二氢铵溶液-甲醇为流动相进行梯度洗脱,进样量20 μL,流速0.8 mL/min,柱温30 ℃,采用双波长检测。结果 生半夏共有10个共有峰,通过对照品比对指认了其中5个共有峰;伪品半夏中同时含有8种有效成分;随机选取部分生半夏与伪品半夏样品建立叠加指纹图谱得出:虎掌南星于34~38 min出现2个特征峰;姜水半夏在32~34 min出现2个特征峰;而水半夏出峰整体峰高较低,峰面积偏小。结论 建立的指纹图谱特征性强,能明显区分半夏与其伪品水半夏及虎掌南星,可用于半夏的鉴别和质量控制。 |

OBJECTIVE To develop a high performance liquid chromatography (HPLC) method for the fingerprint analysis of Pinellia ternata <\i>and its authenticity identification. METHODS HPLC analysis was performed on a SB-Aq column(4.6 mm×250 mm, 5 μm) with the mixture of 0.2% ammonium dihydrogen phosphate solution ( pH=3.0) (A) and methanol (B) as mobile phase in gradient mode. The column temperature was set at 30 ℃ and dual wavelength detection was used. RESULTS The HPLC fingerprint of Pinellia ternata<\i>,showing 10 characteristic peaks,was established from raw Pinellia ternata<\i>, and 5 were identified by standard comparison, and 8 common constituents were identified in fake Pinellia ternata <\i>samples. An overlay fingerprint were established with samples randomly selected: From 34 to 38 min,there were two characteristic peaks in the Pedate Rhizome Pinellia<\i>, and two appeared at 32 to 34 min in the Rhizoma Typhonii Flagelliformis <\i>prepared with ginger juice,while the peak height in the raw Typhonii flagelliformis Rhizoma <\i>was lower and the peak area was smaller. CONCLUSION The fingerprint of Pinellia ternata <\i>is significantly different from its confused herbs, which can be applied to the identification and quality control of Pinellia ternata. |
