Abstract From the Uncaria rhynchophlly (Miq.) Jacks, twelve monoterpene indole alkaloids, such as harman (1), strictosamide (2), vincosidelactam (3), cadambine (4), 3α-dihydrocadambine (5), 7-epi-javaniside (6), rhynchophylline (7), isorhynchophylline (8), hirsutine (9), vincosamide-6′-O-β-D-glucopyranoside (10), vincosamide-11-O-β-D-glucopyranoside (11) and 2′-O-[β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranosyl]-11-hydroxyvincosamide (12) were isolated and identified. Structure elucidation of these compounds was performed on the basis of NMR spectroscopic data. Compounds 2, 5, 6, 10, 11 and 12 were obtained from this species for the first time. Chemotaxonomic significance of these compounds is described herein.
