Abstract
Classical extraction methods used for isolation of active substances from plant materialare expensive, complicated and often environmentally unfriendly.The ultrasonic assistancemicelle-mediated extraction method (UAMME), based on green chemistry principles, seems tobe an interesting alternative. This work aimed to find a connection between the chemical structure ofnon-ionic surfactants and the efficiency of the extraction process. The effect of hydrophobic chainlength and number of ethoxy groups on the quality ofBidens tripartiteextracts was investigated.Several ethoxylated fatty alcohols were used: Ceteareth-20, Steareth-20, Oleth-20, Oleth-10, Oleth-5,C12-C13 Pareth-12, C12-C15 Pareth-12 and Ceteareth-12. The bioflavonoid compositions with theHPLC method was determined. The hydrophilic lipophilic balance (HLB) of studied surfactants,as well as the surface tension of surfactant solutions, were compared, to determine the explanationfor the obtained differences in bioflavonoids concentration. The structural changes influencedby polyphenol extraction were monitored using Dynamic Light Scattering (DLS) measurements.In this work, probably for the first time, the connection between the chemical structure of non-ionicsurfactants and the efficiency of the extraction process was found. The experimental and theoreticalapproach rationalized the choice of an appropriate eluent. We propose some structurally dependentfactors, whose optimal value gave a high efficiency to the UAMME.
