In vitro antifungal potentials of bioactive compound oleic acid, 3-(octadecyloxy) propyl ester isolated from Lepidagathis cristata Willd. (Acanthaceae) inflorescence

ABSTRACTObjectiveTo identify bioactive compound oleic acid, 3-(octadecyloxy) propyl ester from Lepidagathis cristata Willd. (L. cristata) and to assess antifungal potentials of the isolated compound.MethodsAqueous extracts of L. cristata inflorescence were used for this study. The major bioactive compound isolated was tested for antifungal activities.ResultsThe major bioactive compound oleic acid, 3-(octadecyloxy) propyl ester was isolated from the inflorescence of L. cristata. The bioactive compound was tested for antifungal potentials and found to be highly effective to plant pathogenic fungi Colletotrichum fulcatum NCBT 146, Fusarium oxysporum NCBT 156 and Rhizoctonia solani NCBT 196 as well as for the human pathogenic fungi Curvularia lunata MTCC 2030 and Microsporum canis MTCC 2820.ConclusionsThe results justify the antifungal potentials of both plant and human pathogenic fungi. The plant bioactive compound will be helpful in herbal antifungal formulations.
