The phenolic content of extracts was observed to increase in the following order: methanol>ethyl acetate>ethanol>dichloromethane. Although, the highest solubility of sterols observed in the ethyl acetate extract, might contribute to the highest antioxidant activity observed in this extract, there was ...
In fact, BIC model evidenced the existence of a selectivity advantage favorable to stigmasterol that is driven by kinetics rather than by solubility, which is corroborated by the fact that shorter extraction periods were noticed in stigmasterol yield curves than in the global extract yield curves. ...
Due to the low oil solubility and bioavailability of free stigmasterol, it is worth focusing on increasing its supply to the target tissues by its conjugation with other hydrophobic molecules. In this aspect, we paid our attention to acylglycerols, which, due to their natural presence both in ...
