peritassa smaragdina/sesquiterpene

An investigation of the methanol and ethyl acetate extracts from the roots of Peritassa campestris (Hippocrateaceae) afforded the sesquiterpene pyridine alkaloid, 4-hydroxy-7-epi-chuchuhuanine E-V, and nine known alkaloids, forrestine, euonimine, ebenifoline E-I, wilforine, euojaponine F, euonine,

Sesquiterpene pyridine alkaloids were analysed in Peritassa campestris by mass spectrometric techniques such as ESI-MSMS and GCMS. Ten alkaloids previously isolated from this plant and fully identified by other physical methods, including NMR spectroscopy and X-ray diffraction, were carefully
