Rocío Barreiro Rodríguez

Chemist specializing in the field of Analytical Chemistry, highlighting the use of chromatographic techniques.

During her master's studies at the University of Barcelona she carried out a research project focused on water analysis using gas chromatography.

In the research carried out in the Ph.D., focused on the characterization of camellia oil and tea from Galician camellias, gas chromatography coupled to mass spectrometry, HPLU-DAD, 1H-NMR and other techniques were used for the analysis of the samples following a wide range of procedures. The work developed at the Areeiro Phytopathological Station during the Ph. D., included the direction and execution of sampling, sample treatments, optimization of the oil extraction method and development and application of different analysis methods for physical-chemical characterization of camellia oil and aqueous extracts of Camellia sinensis leaves (tea).

Camellia genus (Theaceae) is comprised of world famous ornamental flowering plants. C. japonica L. and C. sasanqua Thunb are the most cultivated species due to their good adaptation. The commercial interest in this plant linked to its seed oil increased in the last few years due to its health attributes, which significantly depend on different aspects such as species and environmental conditions. Therefore, it is essential to develop fast and reliable methods to distinguish between different varieties and ensure the quality of Camellia seed oils. The present work explores the study of Camellia seed oils by species and location. Two standardized gas chromatography methods were applied and compared with that of data obtained from proton nuclear magnetic resonance spectroscopy (1H-NMR) for fatty acids profiling. The principal component analysis indicated that the proposed 1H-NMR methodology can be quickly and reliably applied to separate specific Camellia species, which could be extended to other species in future works.
