Abstract:
Objective To study the chemical constituents in fruits of Catalpa ovata.Methods Various chromatographic techniques were used to separate and purify the constituents.Structures of the compounds were elucidated by physicochemical properties and spectral analysis (UV, IR, ESI-MS, 1H-NMR , 13 C-NMR , 1H- 1H COSY , HMQC, HMBC, NOESY, and CD).Results A compound was isolated and identified as 2(S)-(3′-hydroxy-5′-methoxy)-benz-3(S)-ethoxycarbonyl-6-trans-ethyl acrylate-8-methoxy-benzofuran.Conclusion This compound is a novel compound named as catalpafurxin.
