摘要: 为建立斑地锦(Euphorbia maculata L.)的HPLC指纹图谱分析方法并进行鉴别,采用PBONTOSIL KROMAPLUS 100-5-C18色谱柱(250 mm×4.6 mm,5 μm);以乙腈-0.1%磷酸系统为流动相,梯度洗脱:流速为0.8 mL/min;检测波长为360 nm;柱温为25 ℃。结果显示,斑地锦与千根草(Euphorbia thymifolia L.)、匍匐大戟(Euphorbia prostrata Ait.)、台西地锦[Euphorbia taihsiensis (Chaw et Koutnik) Oudejians]的HPLC指纹图谱均存在较显著差异;建立的HPLC指纹图谱方法能有效鉴别斑地锦及其近缘种。

Abstract: In order to establish and identify HPLC fingerprint analysis method of Euphorbia maculata L., PBONTOSIL KROMAPLUS 100-5-C18 column (250 mm × 4.6 mm, 5 μm) was used. Acetonitrile-0.1% phosphoric acid system was used as the mobile phase for gradient elution:Flow rate was 0.8 mL/min; detection wavelength was 360 nm; column temperature was 25 ℃. The results showed that there were significant differences in HPLC fingerprints between Euphorbia maculata L. and Euphorbia thymifolia L., Euphorbia prostrata Ait., Euphorbia taihsiensis (Chaw et Koutnik) Oudejians. The established HPLC fingerprint method can effectively identify Euphorbia maculata L. and its related species.

Key words: Euphorbia maculata L., related species, HPLC fingerprint, identification
