Sus estructuras fueron establecidas en base a técnicas de análisis espectroscópico de RMN. En base a este estudio los datos de RMN X H y 13C del compuesto (1) fueron completados mediante técnicas de RMN 2D.A known ent-kaurane diterpenoid, ewf-19-al-17,16P-dihydroxykaurane (1), together with the new one, ent-3<img width=9 height=14 src="../img/a07_figura01.gif">, 16<img width=9 height=14 src="../img/a07_figura01.gif">, 19-trihydroxykaurane (2), called leptophyllin, were isolated from aerial parts of Baccharis leptophylla. Their structures were established on the basis of NMR spectroscopic analysis. Based on this study the ¹H and 13C NMR spectral data of compound (1) were completed by means of 2D NMR techniques.esBaccharis leptophyllaBolivian medicinal plañísent-kaurane diterpenoidsleptophyllinent-3<img width=10 height=13 src="../img/a07_figura02.gif">16<img width=10 height=13 src="../img/a07_figura02.gif">19-trihydroxykauraneent-19-al-1716<img width=10 height=13 src="../img/a07_figura02.gif">-dihydroxykauraneArtículo Científico Publicado
