Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

Advanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Regioselective Hydroxylation and Glucosylation of α- and β-Pinenes with Cultured Cells of

Natural Product Communications, 2013
Cultured plant cells of Eucalyptus perriniana regioselectively hydroxylated (+)- and (-)-α-pinenes to the corresponding (+)- and (-)-verbenols. In addition, (+)-and (-)-verbenols were converted into mono-β-D-glucosides.

Studies on Monoterpene Glucosides. VII. Iridoid Glucosides of Paederia scandens

Chemical and Pharmaceutical Bulletin, 1969
Four new glucosides, paederoside (II), paederosidic acid (III), scandoside (IV) and deacetylasperuloside (V) along with asperuloside (I) were isolated as iridoid glucosides from Paederia scandens (LOUR.) MERRILL var. mairei (Leville) HARA and their structures were established. II and III are sulfur-containing glucosides.

Preparation, Component Identification, and Antioxidant Activity of Anthocyanins From Punica granatum “Tunisia”

AgriFood: Journal of Agricultural Products for Food, EarlyView.
The preparation for Tunisian pomegranate anthocyanin extract. The molecular mechanisms underlying the antioxidant effects of these compounds were investigated using network pharmacology and molecular docking. Antioxidant activity was evaluated through DPPH, ABTS, and FRAP assays, whereas the effects on oxidative stress and inflammation were examined in

Guideline for High‐Performance Liquid Chromatography Detection of Anthocyanins

AgriFood: Journal of Agricultural Products for Food, EarlyView.
ABSTRACT Anthocyanins, as water‐soluble natural pigments widely present in plants, have various biological activities such as antioxidation and anti‐inflammatory, and are widely used in the fields of food, cosmetics, and medicine. However, because of the presence of unstable phenolic hydroxyl groups in their structure, they are prone to degradation due
