不同产地单芽狗脊蕨HPLC指纹图谱
摘要
目的:建立不同产地单芽狗脊蕨HPLC指纹图谱测定方法。方法:采用HPLC测定了9个不同产地单芽狗脊蕨样品。色谱条件为DiamonsilTMC18色谱柱(4.6 mm×200 mm
5μm);流动相A相为乙腈
B相为水(梯度洗脱0~60 min 22%A→100%A);检测波长265 nm;流速1.0 mL·min-1;柱温25℃。结果:建立了不同产地单芽狗脊蕨的HPLC指纹图谱
Objective: To establish the fingerprints of Woodwardiae unigemmmata from different habitats by HPLC.Method: HPLC was applied to detect W.unigemmmata samples from 9 different habitats with a DiamonsilTMC18 column by acetonitrile A-water B as mobile phase(gradient elute: 0-60 min
22%-100%A).The flow rate was 1.0 mL·min-1.The column temperature was at 25 ℃ and the UV detection wavelength was set at 265 nm.Result: The HPLC fingerprints of W.unigemmmata from different habitats were established and the correlation coefficients of them were calculated.Furthermore
two peaks in HPLC chromatogram were identified as kaempferol-3-O-α-L-rhamnopyranoside-7-O-α-L-rhamnopyranoside
kaempferol-3-O-α-L-(4-O-acetyl)-rhamnopyranoside-7-O-α-L-rhamnopyran-oside respectively.Conclusion: The method is simple
reproducible and can be used for quality control of W.unigemmmata.
