1. Multivariate spectroscopic methods for the analysis of solutions
Sammanfattning : In this thesis some multivariate spectroscopic methods for the analysis of solutions are proposed. Spectroscopy and multivariate data analysis form a powerful combination for obtaining both quantitative and qualitative information and it is shown how spectroscopic techniques in combination with chemometric data evaluation can be used to obtain rapid, simple and efficient analytical methods.

2. Anti-cancer effects of bioactive compounds from rose hip fruit in human breast cancer cell lines : carotenoids, triterpenes, and ascorbate evaluated singly or in combination
Sammanfattning : Rose hips have long been used in human diets as a food ingredient and supplement. Their multiple medical properties, which have been attributed to their abundant carotenoid composition, have attracted widespread scientific attention. This thesis examined the carotenoid composition in rose hips from five rose species. LÄS MER
3. Evaluation of a Miniaturized Rotating Disk Apparatus for In Vitro Dissolution Rate Measurements in Aqueous Media : Correlation of In Vitro Dissolution Rate with Apparent Solubility
Sammanfattning : The general aim of this thesis was to evaluate a newly designed and constructed miniaturized rotating disk apparatus for in vitro dissolution rate measurements of different drug substances from all of the classes in the Biopharmaceutical Classification System (BCS). The new equipment is based on a low volume flow-through cell of Plexiglas, a gold plated magnetic bar and a special designed press. LÄS MER
