Two neolignan glycosides (junipercomnosides A and B) were isolated from aerial parts of Juniperus communis var. depressa along with two known neolignan glycosides and seven flavonoid glycosides. The structures of the isolated compounds were determined by spectral analysis, in particular by 2D-NMR analysis. The significance of distribution of flavonoids in the chemotaxonomy of genus Juniperus was also discussed.

The Asteraceae family has been of significant concern for ethnobotanical studies, thanks to its health-promoting properties linked to a plethora of bioactive compounds, among which phenolic compounds play a critical role. In this work, a workflow based on computational chemometrics was employed to assess the authenticity and biomarker search of five key Asteraceae species commonly employed in traditional medicine. The UHPLC-DAD-ESI/MS-MS phenolic profile of Asteraceae extracts was combined with the evaluation of several in vitro biological properties.

Gastric cancer (GC) is a malignant tumor with high morbidity and mortality rates worldwide. This study aimed to investigate the effects and mechanisms of action of didymin, a dietary flavonoid glycoside, on GC treatment. Human GC cell lines Hs-746T and AGS were used to assess the effects of didymin on cell viability, cell proliferation, and cell cycle.

In this study, we prepared a new multi-functional intelligent hydrogel preservation film using soy hull nanocellulose (SHNC), polyvinyl alcohol (PVA), chitosan (CS), and anthocyanin (Anth) as raw materials. The physicochemicals of the hydrogel preservation film, and its role in monitoring the freshness and freshness of salmon was evaluated. The results showed that the monomers were crosslinked by hydrogen, ester bonds, and electrostatic interactions in the hydrogel film, and there were three-dimensional pores in the hydrogel film.

The present study aim to investigate the effects of three drying processes on the flavor-related compounds and sensory quality of summer black tea. A total of 234 flavonoids and 1200 volatile compounds were identified in tea samples by using UPLC-MS/MS and HS-SPME-GC-MS, respectively. It was found that the combining hot-air and roasting drying process increased the level of epigallocatechin, epicatechin, gallic acid, theaflavins, and umami and sweet amino acids in tea samples.

Fe-loaded red radish anthocyanin (RRA) and zein composite nanoparticles (FZNPs) were firstly prepared to enhance the color and stability of RRA. The addition of Fe caused anthocyanin to form color chelates, enhancing its pH color sensitivity. The prepared FZNPs showed good stability and anthocyanin retention during long-term storage.
