[Diverse Solvent Effect on Extraction of Chemical Components from Lamiophlomis rotate]
Objective:
To investigate the diverse solvent effect on extraction of chemical components from Lamiophlomis rotata.
Methods:
Based on LC-MS / MS technique, and chromatographic peak comparison, potential chemical components screening and partial least squares-discriminant analysis( PLS-DA) were used to establish a quantitation method for simultaneous determination of chlorogenic acid,forsythoside B,verbascoside,luteoloside,quercetin,luteolin and apigenin.
Results:
According to the results of PLS-DA and quantitative analysis, methanol, water-saturated n-butanol,75% methanol and 50% methanol showed wider extraction range and higher extraction efficiency to the chemical components of Lamiophlomis rotata.
Conclusion:
This study offeres references to the extraction technology of Lamiophlomis rotata, and promotes the relative pharmacodynamics study of this medical material.
