Constituintes químicos de Hyptidendron canum (Pohl ex Benth.) R. Harley (Lamiaceae)
Chemical investigation of Hyptidendron canum stems resulted in the isolation of betulinic, ursolic and euscaphic acids. From the leaves were isolated 3β-O-β-galactopiranosilsitosterol, ursolic aldehyde, and mixtures of maslinic acid and 2α-hydroxyursolic

The new technique, by exploiting and modifying the partition coefficients of various molecules in immiscible solvents, makes it possible to obtain olive oils rich in polyphenols with outstanding characteristics. Moreover, the extension of this technique allows the transfer of polyphenols present in vegetation water into any lipid matrix, such as seed ...

Avocado Oil: Commercial Hass Versus Other Varieties—Fatty Acid Profile and Quality
Avocado oils vary in their fatty acid profiles depending on the variety. We compared commercial Hass avocado oils with local Brazilian varieties and olive oils, finding that some non‐commercial varieties, such as Primavera and Galavote, exhibit a quality similar to olive oil.

In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...
