The MAE was able to extract the highest amount of spilanthol from in vitro whole plant (3.09%) compared to the classical maceration extract (0.98%) and, furnished good crude extracts yields under an optimized study accurately explained by the mathematical model.
None of the tested compounds alone inhibited C. albicans growth at concentrations which are present in 160 µg/ml of S. boulardii extract (the highest amount used in the experiments).
The methanol extract contained the highest amount of crude extract.
Among the three extracts of stem bark of C. griffithii, the acetone extract contained the highest amount of total phenolics and flavonoids and showed maximum antioxidant, antibacterial, cytotoxic (IC50 of 35.5 ± 0.6 μg/ml; P < 0.05), and apoptotic (46.3 ± 3.6%sub-G0/G1sub-G0/G1ion; P < 0.05) activity, followed by the methanol and petroleum ether extracts.
The total phenolic content of Kensington Pride, Irwin and Nam Doc Mai peel and flesh extracts has been recently reported with Nam Doc Mai peel extract containing the highest amount of polyphenolics [ 12].
The ethyl acetate extract showed the highest amount of TFD, whereas the lowest amounts of TPC, TFD and TFL were found in the chloroform extract.
Centaurea cheirolopha extract, with the highest amount of total phenolic and flavonoids, showed the highest antioxidant activities in all assay, except for metal chelating.
In particular when using image processing for classification, these steps majorly influence the achievable classification results because extracting features from images concern extracting the highest possible amount of information.
Supercritical fluid extraction (SFE) of sardine oil was performed to optimize various parameters, such as pressure, temperature, CO2 rate and time in order to obtain the highest yield of extracted oil with the highest amount of EPA and DHA in the extraction product.
