New feruloyl tyramine glycosides from Stephania hispidula YAMAMOTO

Three new feruloyl tyramine glycosides, N-cis-feruloyl tyramine-4'''-O-beta-D-glucopyranoside (1), N-trans-ferloyl tyramine-4'''-O-beta-D-glucopyranoside (2), and N-trans-feruloyl tyramine-4'-O-beta-D-glucopyranoside (3), along with six known compounds, N-trans-feruloyl-3'''-methoxydopamine-4'-O-beta-D-glucopyranoside (4), haitinosporine (5), tubocurine (6), fuzitine (7), (+)-lyoniresinol-3alpha-O-beta-D-glucopyranoside (8), and (-)-lyoniresinol-2alpha-O-beta-D-glucopyranoside (9), were isolated from the stem of Stephania hispidula YAMAMOTO. The structures were elucidated by spectroscopic and chemical analysis.
