Acutaxylines A and B, two novel triterpenes from Dysoxylum acutangulum [PDF]

, 2009
Two novel triterpenes, acutaxylines A (1) and B (2) consisting of a cyclopentenone side chain at C-17 and an oxepan-2-ol, were isolated from the leaves of Dysoxylum acutangulum. The relative stereochemistry of 1 and 2 was determined by NOESY correlations.

Manganese Porphyrin‐Catalyzed One‐Pot Oxidation of Lupeol: Efficient Conversion of Its Terminal Alkene Into Carboxylic Acids

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Manganese porphyrin catalyst enables green PhI(OAc)2 oxidation of lupeol in ethyl acetate, achieving 94% conversion and the formation of eight products, including selective C20 olefin transformations and one‐pot conversion of the isopropenyl group to carboxylic acids, all without the need of C3‐OH protection step.

The incorporation of alpha-tocopherol and functional doses of phytosterol esters during cheesemaking does not affect DNA or mRNA dynamics of Streptococcus thermophilus and Lactococcus lactis throughout and after the end of ripening [PDF]

, 2017
Tocopherols and phytosterols are lipid-soluble molecules which have been widely used in the food industry. Nevertheless, the influence of these compounds on the performance of starter lactic acid bacteria (SLAB) in fermented foods has received little ...

Major Components of Epicuticular Wax From Fruit of the Canadian Prairies: Saskatoon Berry (Amelanchier alnifolia), Canadian Dwarf Sour Cherry (Prunus × kerrasis), Haskap (Lonicera caerulea), and Red Twinberry (Lonicera utahensis)

European Journal of Lipid Science and Technology, Volume 128, Issue 5, May 2026.
Composition of chloroform extractable surface wax from fruit was determined by GC and GC/MS. The major components of Saskatoon berry wax were nonacosan‐10‐ol and nonacosane. Canadian sour cherry wax was enriched in the pentacyclic triterpenoids and haskap in nonacosan‐10‐ol and nonacosan‐5,10,‐diol. Red twinberry wax contained triterpenoids.

Second‐Generation Crystalline Sponges Enabling Consistent Structure Analysis Under Standardized Conditions for Diverse Molecules

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
The second‐generation crystalline sponge method allows structurally diverse molecular guests to crystallize under standardized crystallization conditions. The key is the predominant packing type of cages and anions in crystals. ABSTRACT Crystallization is typically highly sensitive to even minor structural differences in target molecules.
