Isolation of stilbenoids from fresh knotwood of Scots pine using a high yield method

Scots pine knotwood contains valuable amount of
stilbenoids such as pinosylvin (Ps) and pinosylvin monomethyl
ether (PsMME). The stilbenoids have numerous
biological activities. Traditional methods of extracting
stilbenoids often yield low quantities and involve complex
processes. In the present study, a simple and high-yield
method was proposed for the extraction of stilbenoids from
fresh Scots pine knotwood using ethanol taking a total of
three days. In addition, the impact of drying process,
extraction time, extraction solvents (acetone and ethanol)
and storage time were evaluated on the yield of the stilbenoids.
The increased yield and improved extraction efficiency
make this method a promising advancement for
promoting the utilization of stilbenoids for their valuable
bioactive properties.
