Essential oils obtained by hydrodistillation from leaves and spikes of Piper lanceaefolium H.B.K. of Costa Rica were analysed by GC-FID, GC-MS and 13C-NMR methods. Main constituents found in the oil from leaves were sesquiterpene hydrocarbons - especially beta-caryophyllene and germacrene D - and phenylpropanoids, of which elemicin and parsley apiol were the major ones. The volatile oil from spikes showed monoterpene hydrocarbons, namely alpha- and beta-pinene, and the same phenylpropanoids as in the oil from leaves as the major constituents. Results obtained in the analysis by GC-FID and GC-MS of the essential oils from individual plants of different geographic origin were submitted to chemometric cluster analysis and principal component analysis, showing the presence of three different types of oils (i) parsley apiol/elemicin, (ii) elemicin/parsley apiol/dill apiol, and (iii) parsley apiol/dill apiol.
采用气相色谱 - 氢火焰离子化检测器（GC - FID）、气相色谱 - 质谱联用仪（GC - MS）和碳 - 13核磁共振（¹³C - NMR）方法，对从哥斯达黎加的兰叶胡椒（Piper lanceaefolium H.B.K.）的叶片和穗状花序中通过水蒸馏法获得的精油进行了分析。在叶片精油中发现的主要成分是倍半萜烃类——尤其是β - 石竹烯和杜松烯D——以及苯丙素类化合物，其中榄香素和欧芹芹酚是主要成分。穗状花序的挥发油主要成分是单萜烃类，即α - 蒎烯和β - 蒎烯，以及与叶片精油中相同的苯丙素类化合物。对来自不同地理来源的单株植物的精油进行GC - FID和GC - MS分析所获得的结果，进行了化学计量聚类分析和主成分分析，结果表明存在三种不同类型的油：（i）欧芹芹酚/榄香素；（ii）榄香素/欧芹芹酚/莳萝芹酚；（iii）欧芹芹酚/莳萝芹酚。
