摘要:
Using synthesized reference compounds a screening for benzyl, 2-phenylethyl, geranyl, citronellyl, and 2,5-dimethyl-4-hydroxy-3(2H)-furanone 6'-O-malonyl beta-D-glucopyranosides in various plant tissues was performed by high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS/MS). The results obtained with fruits (guava; raspberry; strawberry), leaves (green tea; vine), and mountain papaya (Carica pubescens) peel indicate that malonylation of glycoconjugates is a common pathway in plant secondary metabolism.
