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-beta-caryophyllene (11.6%) and germacrene D (10.7%) followed by alpha-selinene (7.8%), beta-pinene (5.4%), beta-selinene (4.8%), and alpha-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 beta-elemene (5.1%), trans-beta-caryophyllene (5.1%), curzerene (4.9%), and germacrene B (4.5%). Trans-beta-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).
披针叶胡椒（Piper lanceaefolium Kunth）和糙毛胡椒（Piper hispidum Sw.），常被称为消肿草（因其具有抗炎活性）或科德胡椒。胡椒科植物的叶子采自哥伦比亚西北部乔科省的不同地区，并由哥伦比亚国家植物标本馆的植物学家进行鉴定，每个标本的凭证都存放在那里（分别为编号COL 519993和编号COL 519969）。通过微波辅助水蒸馏法（MWHD）获得精油，并采用气相色谱 - 质谱联用仪（GC - MS）进行分析。披针叶胡椒精油为倍半萜类（71.7%）。该成分由倍半萜烃类（58.5%）及其含氧衍生物（13.2%）组成；主要化合物为反式-β-石竹烯（11.6%）和杜松烯D（10.7%），其次是α-芹子烯（7.8%）、β-蒎烯（5.4%）、β-芹子烯（4.8%）和α-荜澄茄烯（4.3%）。糙毛胡椒精油也是倍半萜类（74.4%），含氧倍半萜类（46.4%），其次是倍半萜烃类（28.0%）。主要化合物为反式橙花叔醇（23.6%）和氧化石竹烯（5.4%），其次是β-榄香烯（5.1%）、反式-β-石竹烯（5.1%）、姜黄烯（4.9%）和杜松烯B（4.5%）。反式-β-石竹烯在两种植物精油的共同化合物中所占比例最高（在披针叶胡椒和糙毛胡椒中分别为11.6%和5.1%）。
