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,并进行了相似度比较,进一步对其中的山柰素-3-O-α-L-鼠李糖基-7-O-α-L-鼠李糖苷、山柰素-3-O-α-L-(4-O-乙酰基)鼠李糖基-7-O-α-L-鼠李糖苷进行了归属。结论:该法操作简便、重复性好,可用于单芽狗脊蕨质量控制。
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.
