Phytochemistry and Biological Activities

A new kaempferol glycoside, kaempferol-3-O-β-d-glucopyranoside-7-O-α-l-arabinofuranoside (1), was isolated from the EtOH extract of Pyrrosia petiolosa together with six known flavonoids already reported from the same plant. Structural elucidation was performed by means of physico-chemical methods including MS, and 1D and 2D NMR spectroscopy.
