Liu Y, Wagner H, Bauer R
Phenylpropanoids and flavonoid glycosides from Lysionotus pauciflorus
Phytochemistry 48(2) (1998)
339-343
A new phenylpropanoid glycoside, α-(3,4-dihydroxyphenyl)ethyl-(2'-O- α-L-rhamno-pyranosyl-3'-O-β-D-apiofuranosyl-4'-O-E-caffeoyl)-β-D- glucopyranoside, verbascoside, and two new flayone glucosides, nevadensin 7- O-β-D-glucoside and nevadensin 7-O-[α-L-rhamnosyl(1 → 6)]-β-D-glucoside, have been isolated from the aerial parts of Lysionotus pauciflorus. The structures have been elucidated on the basis of spectroscopic data and chemical correlation.
