<i>Pinaceae</i> plants are widely distributed in the world, and the resources of pine leaves are abundant. In the extensive literature concerning <i>Pinus</i> species, there is much data on the composition and the content of essential oil of leaves. Still, a detailed comparative analysis of volatile terpenes and terpenoids between different species is missing. In this paper, headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry was used to determine the volatile terpenes and terpenoids of typical <i>Pinus</i> species in China. A total of 46 volatile terpenes and terpenoids were identified, and 12 common compounds were found, which exhibited a great diversity in the leaves of <i>Pinus</i> species.

The results of principal component analysis and cluster analysis showed that the leaves of the six <i>Pinus</i> species could be divided into two groups. The species and contents of volatile terpenes and terpenoids in the leaves were quite different. The results not only provide a reference for the utilization of pine leaves resource, but also bring a broader vision on the biodiversity. |
