  • Three tropane alkaloids, 1–3, were isolated from Erythroxylum caatingae, i.e., 6β‐benzoyloxy‐3α‐[(4‐hydroxy‐3,5‐dimethoxybenzoyl)oxy]tropane (1), a new tropane alkaloid, along with the known alkaloids 3α,6β‐dibenzoyloxytropane (2) and 6β‐benzoyloxy‐3α‐[(3,4,5‐trimethoxybenzoyl)oxy]tropane (catuabine B; 3). Their structures were determined by 2D‐ (1H and 13C) NMR. By LC/ESI‐MS/MS analysis of the fractions of alkaloids 1–3, it was possible to detect five more alkaloids, 4–8, two of these, 4 and 8… CONTINUE READING
