Abstract
Passiflora garckei cell cultures were used as a model to describe a reproducible sample preparation method. Solid phase extraction (SPE) was employed to isolate the plant metabolites for nuclear magnetic resonance (NMR) analysis and to subsequently detect the differences between yeast extract elicited and control cells. Compared with previous results obtained by using a Sephadex LH-20 column, SPE coupled with NMR spectroscopy improves the analysis of aromatic compounds e.g.: trans-feruloyl derivatives and trans-coumaroyl derivatives. Moreover, it decreases the concentration of sugars that usually overlap with many plant metabolite signals.
