ABSTRACT

The flavonoids 5-hydroxy-7,8,4'-trimethoxy isoflavone and 5,3',4'-trihydroxy-7-methoxyflavanon ,the tannin derivate Ethyl gallate and lignang homoegonol 5-(3''-Hydroxypropyl)-7-methoxy-2-(3',4'-dimethoxyphenyl)benzofuran were isolated and purified from Polygonum segetum Kunth leaves using column chromatography and thin layer chromatography methods. These substances were identified on the basis of their physical properties (melting point and Rf value), qualitative chemical reactions and spectroscopic techniques UV and NMR (experiments 1H, 13C, 1H-1H COSY, HMQC) and spectrometric techniques GC-MS according to their complexity.


El presente estudio se encaminó a determinar los metabolitos secundarios presentes en las hojas de la especie vegetal: Polygonum segetum Kunth, colectada del humedal Juan Amarillo (Bogotá-Colombia). Como resultado se aislaron e identificaron a partir de propiedades físicas y técnicas espectroscópicas de UV, 1HRMN, COSY, DEPT 135, HMQC y APT, la 5-hidróxi-7,8,4´-trimétoxi isoflavona, el galato de etilo (derivado de taninos) y la 5,3´,4´-trihidróxi-7-metóxi flavanona. Además, por análisis GC-MS se identifico el lignano 5-(3,4-dimetóxifenil)-7-metóxibenzofuranpropanol homoegonol.
