URZUA, ALEJANDRO; MODAK, BRENDA  y  TORRES, RENE. IDENTIFICATION OF A NEW AROMATIC GERANYL DERIVATIVE IN THE RESINOUS EXUDATE OF HELIOTROPIUM FILIFOLIUM (BORAGINACEAE). Bol. Soc. Chil. Quím. [online]. 2001, vol.46, n.2, pp. 175-178. ISSN 0366-1644.  doi: 10.4067/S0366-16442001000200011.

A new aromatic geranyl derivative was isolated from the resinous exudate of Heliotropium filifolium. The structure was elucidated by high-resolution spectroscopic methods as filifolinyl senecionate. The compound has shown antibacterial activity against Escherichia coli K-12. After irradiation of a solution of filifolinyl senecionate with UV at 366 nm, the antibacterial activity was enhanced by 100%
