Resumen

This study aimed to obtain chamomile flower extracts (CFEs) using supercritical CO2 (200 bar and 40 °C) and analyze their composition by GC-MS. A yield of 2.8 ± 0.3% of CFE was obtained after 122.4 min of extraction. The CFE contained several compounds, the most abundant of which were 4-(4-Hydroxy-2,2,6-trimethyl-7-oxabicyclo [4.1.0]hept-1-yl)butan-2-one (12.9%), (Z)-Tonghaosu (11.8%), 6-hydroxydihydrotheaspirane (11.5%), pentacosane (8.1%), cyclohexanethiol, 2,5-dimethylacetate (5.6%), and tetracontane (5.3%). The SFE process for obtaining CFE compounds is a suitable alternative; however, further studies are needed to evaluate this process and the composition of the extract, especially its most volatile fraction.
