Flavonoids from Pyrrosia petiolosa (Christ) Ching.
A new kaempferol glycoside, kaempferol-3-O-beta-D-glucopyranoside-7-O-alpha-L-arabinofuranoside (1), was isolated from the EtOH extract of Pyrrosiapetiolosa 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.
