Acetylation‐Deacetylation‐Driven Natural Product Biosynthesis

ChemistryEurope, EarlyView.
This review summarizes the role of acetylation‐deacetylation in natural product biosynthesis, including acetylation followed by deacetylation after several biosynthetic steps, acetylation‐mediated rearrangement, acetylation‐triggered elimination, and the acetylation cycle as a regulatory mechanism. These processes are vital for the formation of complex

Selection of the promising accessions of jamun (Syzygium cumini (L.) skeels) based on pomological characterizations

Food Science &Nutrition, Volume 11, Issue 1, Page 470-480, January 2023., 2023
The obtained results are useful for designing conservation strategies for the germplasm as well as implementing breeding programs such as introducing cultivars with different goals such as early or late ripening and seedless, non‐astringent, large, and deeper color‐fruits.

Antioxidant and antimicrobial potential of water lily extracts and their effects on the quality of frozen Nile tilapia (Oreochromis niloticus) fillets

Food Science &Nutrition, Volume 11, Issue 1, Page 535-544, January 2023., 2023
Extension of shelf life using natural antioxidant like water lily extracts is desirable for highly perishable seafood preservation than the synthetic one. In this study, water lily ethanolic extract has considerable amount of antioxidant and antimicrobial potentiality, which effectively reduced the quality deterioration, inhibited the lipid oxidation ...

Asymmetric Total Synthesis of (+)‐ and (−)‐Myrioneurinol Employing a “Resolutive” Late‐Stage Barton‐McCombie Deoxygenation

Chemistry – A European Journal, EarlyView.
The total syntheses of (+)‐ and (−)‐myrioneurinol are described. This was achieved through two key steps based on a Prins‐type alkenylation of activated phenols to construct the central cycle of this natural substance, and a late‐stage “resolutive” Barton Mc‐Combie reaction which allowed the separation as well as the deoxygenation of both enantiomers ...

Identification of compounds from chufa (Eleocharis dulcis) peels by widely targeted metabolomics

Food Science &Nutrition, Volume 11, Issue 1, Page 545-554, January 2023., 2023
The big Chinese water chestnut (BCWC) and small Chinese water chestnut (SCWC) peels using ultraperformance liquid chromatography/mass spectrometry (UPLC/MS)‐based metabolomics analysis. A total of 321 significant metabolites, including 90 flavonoids, 25 phenylpropanoids, and 33 organic acids and derivatives, were identified/annotated from BCWC and SCWC.
