Abstract
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, wilforjine, neowilforine, and wilforzine. The structures of the isolates were elucidated on the basis of spectral data, particularly HMQC and HMBC experiments.
