title: Caudatosides A-F: new iridoid glucosides from Citharexylum caudatum.
abstract: Six new iridoid glucosides, caudatosides A-F (2-7), and one known iridoid glucoside, 5-deoxypulchelloside I (1), were isolated from the fruits of Citharexylum caudatum. The structures of these compounds were elucidated by various one- and two-dimensional NMR techniques as well as high-resolution negative-ion ESIMS. Other plant parts were extracted on a small scale, and TLC of these extracts revealed the presence of the same iridoids.
