| dc.description.abstract | Extracts were obtained from Matricaria recutita L. flowers by cold solvent extraction using
different solvents, Clevenger distillation and solvent extraction combined with Clevenger
distillation (SECD); this was done to compare the yield and quality of the different extracts
providing information for optimization of extraction and the composition of flowers from
selected regions. The extracts were characterized using TLC, UV-Vis spectrometry, IR
spectrometry and GC-MS. UV-Vis scanning and measurement of refractive index (R.I) of the
chamomile essential oil were carried out at monthly and/or bi-monthly intervals to determine if
they could be used to monitor the stability and changes in quality of the essential oil. Isolation of
components of chamomile essential oil by preparative TLC was also done to obtain standards
that can be used for future characterizatio. | en |
