Ločba lignanov jelke (Abies alba) s tankoplastno kromatografijo : diplomski projekt = Separation of simple fir lignans (Abies alba) by thin layer chromatography : B. Sc. thesisKosem, JožeRaziskovali smo primeren sistem topil za ločbo lignanov jelke s tankoplastno kromatografijo. Vzorcem grč jelke smo določili delež suhe snovi. S Soxthletovo ekstrakcijo smo ekstrahirali vzorce jelke. ... Prva ekstrakcija je bila s cikloheksanom, druga pa z mešanico acetona in vode v razmerju 95:5. Iz dobljenih ekstraktov smo določili delež suhe snovi v ekstraktu. Opravili smo tudi ekstrakcijo z acetonom, brez predhodne ekstrakcije s cikloheksanom. Dobljene vzorce ekstraktov smo nato nanašali na TLC plošče in jih razvijali v mobilni fazi, za kar smo uporabili diklorometan in etanol v volumskem razmerju 93:7. Za vizualizacijo lis smo uporabili reagent H2SO4 / etanol v volumskem razmerju 50:50. Lisam na kromatogramu smo določili zadrževalni faktor. Na osnovi primerjave naših rezultatov s podatki iz literature smo določili tudi nekatere organske snovi, ki so bile v ekstraktu grč jelke.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
