β-Carboline-type indole alkaloid glycosides from Ophiorrhiza trichocarpon
Six new β-carboline-type indole alkaloid glycosides, ophiorrhisides A-F (1-6), were isolated from Ophiorrhiza trichocarpon (Rubiaceae) collected in Thailand. Ophiorrhisides A (1) and B (2) possess a lactam function in the C ring and a unique biose residue in the molecule. Ophiorrhiside F (6) has a h...
