SALCEDO ORTIZ, Lily; FLORES, Yonny; STERNER, Olov  and  ALMANZA VEGA, Giovanna R.. EAT-KAURANE DITERPENOIDS FROM BACCHARIS LEPTOPHYLLA. Rev. Bol. Quim [online]. 2013, vol.30, n.1, pp.60-65. ISSN 0250-5460.

A known ent-kaurane diterpenoid, ewf-19-al-17,16P-dihydroxykaurane (1), together with the new one, ent-3, 16, 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.

Keywords : Baccharis leptophylla; Bolivian medicinal plañís; ent-kaurane diterpenoids; leptophyllin; ent-3; 16; 19-trihydroxykaurane; ent-19-al-17; 16-dihydroxykaurane.
