Abstract:
Paper spray ionization mass spectrometry (PSI MS) was developed for natural products detection in mango leaves and mango leaves classification. Rapid detection of plant natural products by PSI MS was achieved without complex sample preparation. Many natural products were detected, including medicinally valuable natural products. Principal component analysis (PCA) was applied for the classification of different mango varieties. The PCA result demonstrated clear differentiation between varieties, such as Guifei, Guiqi, and Tainong. This method offers significant advantages for rapid screening of natural products and evaluation of plant utilization value.
