Dereplication of Mammea neurophylla metabolites to isolate original 4-phenylcoumarins

- A small database was acquired from 11 4-phenylcoumarins using LC-DAD-MSn analysis.
- 24 known mammea coumarins were dereplicated from Mammea neurophylla DCM extracts.
- The structure of 4 unreported mammea coumarins could be predicted.
- 2 new mammea coumarins were confirmed after purification and NMR analyses.
