研究目的
To develop a rapid and reliable method for the differentiation of Fritillaria species using MALDI-MS and multivariate statistical analysis.
研究成果
MALDI-MS combined with multivariate statistical analysis effectively differentiated Fritillaria species. The method is rapid, reliable, and provides a metabolomic taxonomy consistent with genetic taxonomy.
研究不足
The study focused on differentiation rather than identification of unknown compounds. The method's applicability to other medicinal herbs needs further validation.
1:Experimental Design and Method Selection:
MALDI-MS was selected for its rapid analysis and tolerance to impurities.
2:Sample Selection and Data Sources:
Dried bulbs of five Fritillaria species were used.
3:List of Experimental Equipment and Materials:
MALDI TOF/TOF mass spectrometer, CHCA matrix, ACN/water extraction solvent.
4:Experimental Procedures and Operational Workflow:
Samples were extracted, mixed with matrix, spotted onto MALDI target, and analyzed.
5:Data Analysis Methods:
Multivariate statistical analysis including PCA, PLS-DA, and OPLS-DA was performed.
