(+)-13α-(4′-Hydroxytigloyloxy) lupanine from Ormosia krugii
摘要:
A new quinolizidine alkaloid ester, (+)-13alpha-(4-hydroxytigloyloxy) lupanine, was isolated from the seeds of Ormosia krugii and spectroscopically characterized, together with five known alkaloids, (+)-lupanine, (+)-alpha-isolupanine, (-)-angustifoline, (+)-11-oxotetrahydrorhombifoline and (+)-13alpha-tigloyloxylupanine. Unambiguous C-13 NMR data have been determined for (-)-angustifoline and (+)-11-oxotetrahydrothombifoline.
