Cissus verticillata L. (Vitaceae) is popularly employed as hypoglicemic and it shows fungitoxic activity. This work aims at identification of fungitoxic compounds on extracts of leaves. The ethanol extract was partitioned using solvents of different polarities (hexane, chloroform, ethyl acetate and butanol) and its fungitoxic activity was analysed upon Cladosporium sphaerospermum. The chloroform and ethyl acetate extracts showed activity and they were fractionated by column chromatography and preparative TLC, respectively. Three terpenoids were isolated from the chloroform extract, one of them identified by GLC-MS analysis as sesquiterpene bicyclogermacrene. The active compound of the ethyl acetate extract was identified by HPLC analyses as stilbene resveratrol.
