✦ Synopsis

The essential oils of eight samples of Piper aduncum L., collected at dierent localities of the Amazon region, were analysed by GC±MS. The major component identi®ed in all samples was dillapiole (31.5± 97.3%). Sample A, collected at Serra do Navio (AP), showed a yield of oil and dillapiole content of 3.3% and 31.5%, respectively; sample B, collected at MelgacË o (PA), 1.8% and 50.8%; sample C, collected at Ben®ca (PA), 1.6% and 56.3%; samples D and E, collected at Bele m (PA), 1.2% and 82.2%; 1.5% and 86.9%, respectively; sample F, collected at Manaus (AM), 3.4% and 91.1%; sample G, collected at Road Manaus-Caracaraõ , km 30 (AM), 3.0% and 97.3%; sample H, collected at Cruzeiro do Sul (AC), 3.2% and 88.1%. The yield of oil and dillapiole content of samples of P. aduncum occurring in Malaysia and Fiji showed 1.3% and 64.5%; and 0.5% and 58.0%, respectively. By comparison, the plants growing wild in Amazonas State had the highest oil yield and dillapiole content.
