An array of one- (1HNMR,{1H}-13C NMR, and APT-13C NMR) and two-dimensional NMR techniques (COSY, NOESY, HMQC and HMBC)was used to achieve the structural elucidation and the complete 1H and 13C chemical shift assignments of these naturalcompounds. In addition, the antifungal activity of these compounds against phytopathogenic and human pathogenicfungi was investigated 2007 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32779204 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.79 |
