This study ascertained the accumulation of polyprenol from four Irish conifer species  Picea sitchensis, Cedrus atlantica ‘Glauca’, Pinus sylvestris  and  Taxus baccata  and one flowering tree  Cotoneaster hybrida  using supercritical fluid extraction with carbon dioxide (SFE-CO 2 ) and solvent extraction. The effects of SFE-CO 2  parameters such as temperature (ranged from 40 to 70    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$$^\circ{\rm C}$$\end{document}∘   C), pressure (ranged from 100 to 350 bars) and dynamic time (from 70 min to 7 h) were analysed on the extraction efficiency of polyprenol. Qualitative and quantitative analysis of polyprenol was examined using high-performance liquid chromatography. Results showed that  P. sylvestris  accumulated the highest polyprenol yield of 14.00  ±    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$$0.4$$\end{document}    0.4mg g −1  DW when extracted with hexane:acetone (1:1 v/v).

This study emphasised the potential application of SFE-CO 2  in the extraction of polyprenol as an environmentally friendly method to be used in pharmaceutical and food industries.
