“…Thiamine (vitamin B1) has been identified in sea buckthorn leaves with a content of 1.4 ± 0.1 mg × kg −1 . Quercitrin is a flavonoid found in many plants which has been reported between 0.17 ± 0.01 and 1.84 ± 0.05 mg/g in sea buckthorn leaf tea depending on manufacturer and factory time [ 46 ]. It has antioxidant and anti-inflammatory activity [ 47 ].…”

Phytosynthesized selenium nanoparticles (SeNPs) are less toxic than the inorganic salts of selenium and show high antioxidant and antibacterial activity. Chitosan prevents microbial biofilm formation and can also determine microbial biofilm dispersal. Never-dried bacterial nanocellulose (NDBNC) is an efficient carrier of bioactive compounds and a flexible nanofibrillar hydrophilic biopolymer. This study aimed to develop a selenium-enriched hydrogel nanoformulation (Se-HNF) based on NDBNC from kombucha fermentation and fungal chitosan with embedded biogenic SeNPs phytosynthesized by an aqueous extract of sea buckthorn leaves (SbLEx)—SeNPsSb—in order to both disperse gingival dysbiotic biofilm and prevent its development. We determined the total phenolic content and antioxidant activity of SbLEx. Liquid chromatography–mass spectrometry (LC-MS) and high-performance liquid chromatography (HPLC) were used for the identification of polyphenols from SbLEx. SeNPsSb were characterized by transmission electron microscopy–energy-dispersive X-ray spectroscopy (TEM-EDX), dynamic light scattering (DLS), zeta potential, Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) in small- and wide-angle X-ray scattering (SAXS and WAXS). The hydrogel nanoformulation with embedded SeNPsSb was characterized by SEM, FTIR, XRD, rheology, mucin binding efficiency, contact angle and interfacial tension measurements. We also assessed the in vitro biocompatibility, antioxidant activity and antimicrobial and antibiofilm potential of SeNPsSb and Se-HNF. TEM, DLS and SAXS evidenced polydisperse SeNPsSb, whereas FTIR highlighted a heterogeneous biocorona with various biocompounds. The contact angle on the polar surface was smaller (52.82 ± 1.23°) than that obtained on the non-polar surface (73.85 ± 0.39°). The interfacial tension was 97.6 ± 0.47 mN/m. The mucin binding efficiency of Se-HNF decreased as the amount of hydrogel decreased, and the SEM analysis showed a relatively compact structure upon mucin contact. FTIR and XRD analyses of Se-HNF evidenced an interaction between BNC and CS through characteristic peak shifting, and the rheological measurements highlighted a pseudoplastic behavior, 0.186 N adhesion force and 0.386 adhesion energy. The results showed a high degree of cytocompatibility and the significant antioxidant and antimicrobial efficiency of SeNPsSb and Se-HNF.

“…In analyzing the composition of sea buckthorn leaf tea, ellagic acid total content to 59.12 mg/g ranked first, as the quality control index, while ellagic acid has therapeutic effects in liver cancer, lung cancer, esophageal cancer and other cancers. After crushing sea buckthorn leaves is advantageous to the composition of precipitation ( 85 ). The chemical constituents and extracts of sea buckthorn leaf tea were investigated, revealing significant antioxidant and α-glucosidase inhibitory activities.…”

Sea buckthorn (Hippophae Fructus), as a homologous species of medicine and food, is widely used by Mongolians and Tibetans for its anti-tumor, antioxidant and liver-protecting properties. In this review, the excellent anti-tumor effect of sea buckthorn was first found through network pharmacology, and its active components such as isorhamnetin, quercetin, gallic acid and protocatechuic acid were found to have significant anti-tumor effects. The research progress and application prospect of sea buckthorn and its active components in anti-tumor types, mechanism of action, liver protection, anti-radiation and toxicology were reviewed, providing theoretical basis for the development of sea buckthorn products in the field of anti-tumor research and clinical application.

“…In the China market, olives are usually used for producing fermented olive vegetables, sweets and preserved fruits in China. Furthermore, fruits such as olives, Rosa Roxburghii Tratt , Hippophae, and kiwifruit are processed into beverages (Zbakh & El Abbassi, 2012; Liu et al ., 2019a; Chen et al ., 2020; He et al ., 2022). However, to mask their undesirable taste, many food additives are required.…”

SummaryOlives, which are rich in bioactive compounds, are processed into beverages in China. We investigated the effect of fermentation by Limosilactobacillus fermentum NCU001464 on the physicochemical characteristics, biological activities and phenolic compounds of olive pulp. After fermentation for 48 h, pH and individual sugar content of olive pulp decreased. Lm. fermentum NCU001464 fermentation enhanced the hydroxyl radical scavenging activity and the inhibitory effect against xanthine oxidase (XO) of olive pulp. Total phenol content was not significantly different between olive pulp fermented for 0 and 48 h. However, the fermented olive phenol extract had a lower IC50 value than the unfermented phenol extract. Fluorescence spectroscopy results revealed that the olive phenol extract had a stronger XO inhibitory effect after fermentation. The dominant binding forces between olive phenols and XO were hydrogen bonds and van der Waals forces. There were 31 different phenolic compounds between the unfermented and fermented extracts.
