Essential oil compositions of aerial parts from two species in the  Piper  ( Piperaceae family ) genera:  Piper lanceaefolium  Kunth and  Piper hispidum  Sw., frequently called deflated (for the anti-inflammatory activity) or cord.  Piperaceae leaves  were collected in different regions of the Chocó department in northwestern Colombia and identified by botanists from Colombian National Herbarium, where a voucher of each specimen were deposited (No- COL 519993 and No- COL 519969, respectively). The essential oils were obtained by microwave-assisted hydrodistillation (MWHD) and analyzed by gas chromatography-mass spectrometry (GC-MS). The  P. lanceaefolium  essential oil was sesquiterpenoid type (71.7%). This composition was represented by sesquiterpenes hydrocarbons (58.5%) and by their oxygenated derivates (13.2%); the main compounds were, trans-β-caryophyllene (11.6%) and germacrene D (10.7%) followed by α-selinene (7.8%), β-pinene (5.4%), β-selinene (4.8%), and α-cubebene (4.3%). The  Piper hispidum  essential oil also was sesquiterpene type (74.4%) and oxygenated sesquiterpenes (46.4%) followed by sesquiterpenes hydrocarbons (28.0%). The main compounds were trans-nerolidol (23.6%) and caryophyllene oxide (5.4%) followed by β-elemene (5.1%), trans-β-caryophyllene (5.1%), curzerene (4.9%), and germacrene B (4.5%). Trans-β-caryophyllene presents the higher percentage of the common compounds in the two species' essential oil (11.6% and 5.1% in  P. lanceaefolium  and  P. hispidum , respectively).
