Phytochemical investigations on Polypodium hastatum have led to the isolation of three isomers of coumaric acid glucosides. Their structures were identified as trans-melilotoside (1), trans-coumaric acid-3-O-β-Dglucopyranoside (2), and trans-coumaric acid-4-O-β-D-glucopyranoside (3) by spectroscopic analysis. Compound 2 is a new natural product.
