Myricetin 3-O-beta-D-glucopyranoside may have antioxidant, and anti-inflammatory activities.

In this study, the results revealed that Rhododendron pseudochrysanthum exhibited the best antioxidant activities among 10 native Rhododendron species in Taiwan. Furthermore, based on a bioactivity-guided isolation principle, nine specific phytochemicals were isolated and identified as (2R,3S)-catechin (1), (2R,3R)-epicatechin (1'), (2R,3R)-dihydromyricetin 3-O- β -l-arabinopyranoside (2), (2S,3S)-taxifolin 3-O- β -l-arabinopyranoside (2'), (2R,3R)-taxifolin 3-O- β -l-arabinopyranoside (3), Myricetin 3-O-beta-D-glucopyranoside(3'), rutin (4), hyperoside (5), and quercitrin (6). Of these compounds, 2 and 3 were found to be major bioactive compounds, and their concentrations in the n-butanol (BuOH) fraction were determined to be 52.0 and 67.3 mg per gram, respectively[1]
