A New Flavonol Glycoside from Millettia Pachycarpa

Eight compounds (1-8), including a new flavonol glycoside (1), were isolated from Millettia pachycarpa. Their structures were elucidated based on combination of spectroscopic methods and comparing with data in literatures. Three of them (2, 6 and 8) were obtained from this genus for the first time. Meanwhile, this is also the first time compound 5 has been found from nature. Biological evaluation of all isolates against two cholinesterases (ChEs) is also described.
