The essential oil isolated by hydrodistillation from the aerial parts of Sinningia aggregata (Ker. Gawl.) Wiehler (Gesneriaceae) was analyzed by capillary GC and GC/MS. Seventeen components were identified, representing 91,8% of the total oil. The oil was characterized by a high content of long-chain aliphatic compounds (49,8%) and oxygenated sesquiterpenes (40,2%). The two major components were methyl linoleate (28,4%) and 1-octadecanol (16,9%). Among the sesquiterpenes, (Z)-nerolidol acetate (8,8%), spathulenol (7,8%) and (E)-nerolidol (6,7%) are present in appreciable amounts. Monoterpenes and phenylpropanoids were not found in the oil.
