AI Article Synopsis
- The study is the first to analyze the leaf essential oil of Enantia polycarpa using various chromatographic and spectroscopic techniques, focusing on 52 oil samples.
- Four main groups of essential oil compositions were identified, with β-elemene and germacrene B being the most common in one group, while germacrene D and β-cubebene were prominent in others.
- The research particularly emphasized the quantification of thermolabile components and included C-NMR data for β-cubebene, enhancing understanding of the essential oil's chemical makeup.
Article Abstract
The composition of Enantia polycarpa Engl. & Diels leaf essential oil has been investigated for the first time using a combination of chromatographic and spectroscopic techniques. The compositions of 52 leaf essential oil samples have been subjected to statistical analysis, hierarchical cluster analysis (HCA) and principal component analysis (PCA). Four groups were differentiated, of which the compositions were dominated by β-elemene and germacrene B (Group III, 22/52 samples); germacrene D (Group I, 16/52 samples); β-cubebene (Group IV, 8/52 samples) and by germacrene B and germacrene D (Group II, 6/52 samples). A special attention was brought to the quantification of the thermolabile components, germacrene A, germacrene B and germacrene C, as well as that of their rearranged compounds, β-elemene, γ-elemene and δ-elemene. C-NMR data of β-cubebene have been provided.
