Bionanomaterials: Synthesis, Physico-Chemical and Multivariate Analyses of the Dicotyledonatae and Pinatae Essential Oil/ beta - cyclodextrin Nanoparticles

Abstract

The paper presents a multivariate analysis (PCA-principal component analysis) of the essential oils from Dicotyledonatae and Pinatae classes encapsulated in b-cyclodextrin. The essential oil/b--cyclodextrin complexes were obtained by solution method. Uncomplexed volatile oils and complexes with b--cyclodextrin were analyzed by gas chromatography-mass spectrometry (GC-MS) and thermogravimetry (TG), respectively. In order to evaluate the composition of the encapsulated oil, this was extracted from the complex and analyzed by GC-MS. For the GC data of the uncomplexed essential oils and the complexed ones, a powerful multivariate statistical procedure (PCA) was applied. Samples were very good classified in botanical classes or in uncomplexed and complexed ones using the GC data of the monoterpene compounds.
