Continuation of the series of studies on the chemical components of the aerial parts of Sida glutinosa has resulted in the isolation and characterization of a new fatty acid ester, named pentyl-10,12-dimethyl-11-hydroxyoleate (1). The structure of compound 1 was established on the basis of extensive spectroscopic analysis, including two dimensional (2D) NMR. Compound 1 possessed moderate fungistatic activity (inhibition zone diameter of 12 mm) against Fusarium oxysporum at a concentration of 100 μg after 24 h.
