Absolute Configuration and Biological Evaluation of Novel Triterpenes as Possible Anti-Inflammatory or Anti-Tumor Agents

Molecules, 2022
Two new compounds, ardisiapunine B (1) and ardisiapunine C (2), were isolated from Ardisia lindleyana D. Dietr. Their structures were examined using HR–ESI–MS, IR, (1D, 2D) NMR spectroscopic analyses, single–crystal X–ray diffraction, and ECD calculation.

Contribution of Free Fatty Acids to Emulsion Building and Stability: Understanding the Mechanism From the Case Study of a Crude Red Palm Oil (Elaeis guineensis)—Based Emulsion Consumed in Africa and Known as Achu Soup/Sauce Jaune/Ncha

Food Chemistry International, EarlyView.
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 ...

Discovery of non-squalene triterpenes

Nature, 2022
Abstract All known triterpenes are generated by triterpene synthases (TrTSs) from squalene or oxidosqualene 1 . This approach is fundamentally different from the biosynthesis of short-chain (C 10 –C 25
