Piper sylvestre Lam.(Piperaceae) is one of the four species of pepper that commonly grows in Mauritius. the other three are P. betel L.(2), P. borbonense DC (1, 3), and P. subpeltatum Wild.(3). P. sylvestre is commonly known in Mauritius as" betel marron" or" Liane de poivrier sauvage". It has been used in folk medicine for many years especially against asthma and haematuric fever (1). P. sylvestre is a trailing and climbing shrub with thickened joints and adventitious roots. Leaves are alternate, ovate, acute at the tip, cuneate at the base and with prominent nerves from the base. The pale yellow coloured essential oil with a very sharp peppery odour hydrodistilled from P. sylvestre has not been studied up to now. This oil has now been examined by GLC, GLC/MS, and GLC/FTIR methods.
