- Master's theses (IPM) 
Fruit including berries have been demonstrated to exhibit a broad spectrum of benefits including protection against cardiovascular, neurological, and lung diseases, as well as having antioxidant, antimicrobial, anti-inflammatory, antidiabetic and anti-aging properties. These protective effects are reported to be due to their high content of bioactive compounds, such as vitamin C, vitamin E, phenolic acids, ellagitannins, flavonoids and carotenoids. This thesis has investigated the effect of Nordic climate factors on the concentrations of bioactive compounds in raspberries. The main objective of this thesis was to investigate the effect of environmental factors and potential differences in total amount of bioactive componds, yield, berry weight and corelation between those figures as well as difference in figures between nine (9) different Raspberry cultivars, Rubus idaeus L. cultivars which were planted and are grown in nordic climate with special attention in differences between cultivar Glen Ample and other eight cultivars. Variables that have been studied are Yield, Berry Size, Soluble Solids(SS), pH, Titratable Acids (TA), AA (ascorbic acid-vitamin c), Dry Matter (DM), Color, TPH (total phenols) and Total Monomeric Anthocyanins (TMA). Concentrations of bioactive compounds in the berries were quantitatively analysed by HPLC. For analyses of FRAP, TMA, and TP, KoneLab 30i (Thermo Electron Corp., Vantaa, Finland), a clinical chemical analyzer was used. Experimental data were subjected to analyses of variance (ANOVA) and regression analyses by standard procedures. This study demonstrates that a high variation of chemical fruit composition exist among cultivars tested.
