Constituents from the bark of Tabebuia impetiginosa
Copyright policy )Constituents from the bark of Tabebuia impetiginosa
Thirteen new phenolic glycosides were obtained by further study of constituents from the bark of Tabebuia impetiginosa (MART. ex DC) Standley (Bignoniaceae). The structures of these compounds were determined based on NMR, mass spectral and chemical evidence. Most of them have a glycosyl unit esterified by a benzoic acid derivative.
