| 中文摘要:目的 建立不同产地白首乌药材的指纹图谱，并测定苯乙酮类成分含量，为不同品种白首乌药材的质量控制提供科学依据。方法 采用HPLC-DAD法建立白首乌药材HPLC指纹图谱，同时对4种苯乙酮类成分进行含量测定。其中，色谱柱为Diamonsil C18（4.6 mm× 250 mm, 5 μm），流动相为甲醇-0.1%磷酸梯度洗脱，流速为1 ml/min，柱温为30 ℃，检测波长为260 nm（4-羟基苯乙酮、白首乌二苯酮、2',4'-二羟基苯乙酮）和280 nm（2',5'-二羟基苯乙酮）。结果 泰山白首乌、滨海白首乌及隔山消中化学成分差异显著，隔山消中总苯乙酮类成分含量明显高于滨海白首乌和泰山白首乌。结论 以苯乙酮类成分为评价指标，隔山消的总苯乙酮含量较高，可作为白首乌药材的优质资源。 |

| Abstract:Objectives To provide scientific basis for the quality control of different species of Baishouwu by establishing the HPLC fingerprint of domestic of Baishouwu and determining the main active components of acetophenones. Methods HPLC-DAD method was used to determine the HPLC fingerprints of domestic of Baishouwu. Then, the content of 4 kinds of acetophenones in Baishouwu was determined. The column was Diamonsil C18（250mm×4.6mm, 5μm）with the mobile phase of methanol and 0.1% phosphoric acid at a flow rate of 1.0 ml/min. The detection wavelength of p-Hydroxyl acetophenone, baishouwu benzophenone, 2',4'-Dihydroxy acetophenone was set at 260 nm and 2',5'-Dihydroxy acetophenone at 280 nm respectively. Results The similarity and cluster analysis in HPLC fingerprint showed that the constituents were significantly different among C. bungei, C. auriculatum and C. wilfordii. The content of total acetophenones in C. wilfordii was significantly higher than that in other localities of C. auriculatum and C. bungei. Conclusions Acetophenone could be used as the evaluation index to evaluate the quality of Baishouwu in different origins. The content of total acetophenone in C. wilfordii is the highest, which could be used as the best quality resource of Baishouwu. |
