Two new triterpenoids, lup-20(29)-en-3α,28-diol (1) and lup-20(29)-en-3α,28,30-triol (2), have been isolated from aerial parts of Bupleurum flavum, a native plant of Easter Mediterranean area (Bulgaria, Greece and Turkey). Their structures were elucidated by spectral analysis. The known compounds betulin, betulinic acid, jasminol, together with the lignan nemerosin and eight flavonoids (kaempferol, isokaempferide, gossipetin, quercetin, luteolin, isorhamnetin-3-O-β-D-glucopyranoside, isorhamnetin-3-O-rutinoside, rutin) were also characterized.

Abstract
Two new triterpenoids, lup-20(29)-en-3α,28-diol (1) and lup-20(29)-en-3α,28,30-triol (2), have been isolated from aerial parts of Bupleurum flavum, a native plant of Easter Mediterranean area (Bulgaria, Greece and Turkey). Their structures were elucidated by spectral analysis. The known compounds betulin, betulinic acid, jasminol, together with the lignan nemerosin and eight flavonoids (kaempferol, isokaempferide, gossipetin, quercetin, luteolin, isorhamnetin-3-O-β-D-glucopyranoside, isorhamnetin-3-O-rutinoside, rutin) were also characterized.File in questo prodotto:
