Four tetrahydroisoquinoline-monoterpene glucosides from Cephaelis ipecacuanha
摘要:
Four new tetrahydroisoquinoline-monoterpene glucosides, trans-cephaeloside, cis-cephaeloside, 6-O-methyl-trans-cephaeloside and 6-O-methyl-cis-cephaeloside, have been isolated from the roots of Cephaelis ipecacuanha. Their structures have been elucidated on the basis of chemical and spectral data.
