A New Flavonoid Glycoside from Lysionotus pauciflorus.
Ten flavonoids (1-10), including a new glycoside (nevadensin-7-sambubioside, 7), together with a phenylpropanoid glycoside (11) were isolated from Lysionotus pauciflorus. Their structures were elucidated by a combination of spectroscopic methods and comparing with literature data. Five compounds (1, 3, 4, 8, and 9) were obtained from the family Gesneriaceae for the first time. The new compound was evaluated in vitro for anticholinesterase activities against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), but was found to be inactive.
