O óleo essencial de Sinningia aggregata (Ker. Gawl.) Wiehler (Gesneriaceae) foi extraído por hidrodestilação e analisado por CG e CG/EM. Foram identificados 17 compostos, representando 91,8% do óleo. O óleo é constituído principalmente por compostos alifáticos de cadeia longa (49,8%) e sesquiterpenos oxigenados (40,2%). Os principais componentes foram: linoleato de metila (28,4%), 1-octadecanol (16,9%), acetato de (Z)-nerolidila (8,8%), espatulenol (7,8%) e (E)-nerolidol (6,7%). Monoterpenos e fenilpropanóides não foram encontrados. Este é o primeiro relato de estudo de óleo essencial na família Gesneriaceae.
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.
