Based on UV spectrometry, the extraction yields were superior in acidic M in comparison to W and AA, ensure increased yield in phenolic compounds comparative to flavonoid derivatives.
Methanolic extracts showed superior total phenols content and antioxidant properties and slightly higher extraction yields than ethanolic extracts; however, ethanol is recommended for food applications due to its GRAS (Generally Recognized as Safe) qualification.
Extraction yields were compared to conventional (CE) and Soxhlet extraction.
Extraction yields ranged from 29.78% to 45.38%.
Therefore, extraction conditions are important to maximize extraction yields and enrich the phenolic components.
Figure 2b represents the effect of extraction temperatures and solvent ratios on the extraction yields.
Extraction yields were calculated giving a range 9.16 1.2%.
Overall, extraction yields increase with both pressure and temperature.
Optimal operating conditions, extraction solvents and extraction yields for both methods were established.
Extraction yields of OC were assessed by fortification experiments.
