Analiza vsebnosti proantocianidinov v lesu bukve z UV-Vis Spektrofotometrom : diplomski projekt = Analysis of proanthocyanidins content in beech wood using a UV-Vis spectrophotometer : B. Sc. thesisDemšar, DavorV tem delu smo raziskali vsebnost proantocianidinov v lesu bukve. Drevesa smo posekali v Kočevskem Rogu. Požagali smo jih tako, da smo dobili vsa potrebna tkiva za nadaljno raziskavo. Najprej smo ... izžagali kolute, ki smo jih nato razžagali, zmleli in posušili. Dobljene vzorce smo nato ekstrahirali, izvedli smo po dve ekstrakciji. Najprej smo izvedli ekstrakcijo po Soxhletu. Z njo smo dobili vsebnost vseh snovi, ki so topne v mešanici metanola in vode, ter vsebnost celokupnih hidrofilnih ekstraktivov. Nato smo izvedli še dietiletrsko ekstrakcijo, s katero smo dobili vsebnost lipofilnih ekstraktivov. Vsebnost proantocianidinov smo določili z UV-Vis spektrofotometrijo. Raziskava je pokazala, da imajo največjo vsebnost lipofilnih ekstraktivov vzorci poranitvenega dela, mrtve in žive grče. Najmanjšo vsebnost lipofilnih ekstraktivov smo izmerili v rdečem srcu. Največjo vsebnost celokupnih hidrofilnih ekstraktivov smo našli v mrtvi in živi grči. Najmanjšo vsebnost pa smo izmerili v rdečem srcu. Največjo vsebnost celokupnih ekstraktibilnih snovi smo našli v živi grči, najmanjšo v rdečem srcu. Največjo vsebnost proantocianidinov imajo vzorci mrtve grče, sledijo vzorci žive grče. Najmanjšo vsebnost pa imajo ponovno vzorci rdečega srca. V vseh primerih imajo vzorci rdečega srca najmanjšo vsebnost merjenih substanc.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
