“…MIC values were 0.625-0.5 mg/mL, and MBC values were 2.5 or 5 mg/mL. The crude extract of fungus YG-2 had the highest TPC and the best antibacterial effect, which was consistent with the results of Ju et al (2018) , whose experimental results showed that water extraction of bayberry extract had the highest TPC and antibacterial activity among four solvents. That is, the minimum MIC and MBC of the YG-2 crude extract may be due to its highest TPC.…”

The dried tuber of Alisma orientale (Sam.) Juzep. (AOJ) is a traditional Chinese medicine with high medicinal value. The endophytic fungi of medicinal plants are a treasure house of natural compounds. However, there is a lack of research on the diversity and biological activity of endophytic fungi of AOJ. In this study, high-throughput sequencing technology was used to study the diversity of endophytic fungi in the roots and stems of AOJ, and endophytic fungi with a high output of phenols and flavonoids were screened by chromogenic reaction, and the antioxidant and antibacterial activities and chemical constituents of crude extracts of their fermentation broth were studied. A total of 3,426 amplicon sequence variants (ASVs) belonging to 9 phyla, 27 classes, 64 orders, 152 families, and 277 genera were identified from AOJ. There were significant differences in the endophytic fungal communities of AOJ roots and stems, as well as in the endophytic fungal communities of triangular AOJ and circular AOJ. In addition, 31 strains of endophytic fungi were isolated from AOJ, of which 6 strains had good antioxidant and antibacterial activities. The crude extract of YG-2 had the strongest free radical scavenging ability and bacteriostatic ability, and its IC50DPPH, IC50ABTS, and IC50⋅OH values were 0.009 ± 0.000 mg/mL, 0.023 ± 0.002 mg/mL, and 0.081 ± 0.006 mg/mL, respectively. The results of LC-MS showed that the main component of the crude extract of YG-2 was caffeic acid (10.12 μmol/g). Overall, the results of this study preliminarily elucidated the diversity and community composition of endophytic fungi of AOJ, indicating that AOJ endophytic fungi have abundant secondary metabolites and good antioxidant and antibacterial activities. This study provides an important reference for further research, development and utilization of AOJ endophytic fungi and a theoretical basis for the further development of the endophytic fungus YG-2 (Chaetomium globosum) as a source of antioxidants.

“…Consumer demand for natural antibacterial and antiseptic substances has grown as abuse of toxic synthetic food preservatives and antibiotics has become more widespread (Ju et al, 2017). Recent findings from our laboratory revealed the BE had a significant bacteriostatic effect (Ju et al, 2018). In addition, in previous studies, we also found that BE has a good effect on the treatment of diarrhea (Yao et al, 2011).…”

Bayberries are important sources of phytochemicals. In this paper, the active substances of bayberry extract (BE) were investigated, and based on this, the inhibitory effects of BE on the six tested food-borne pathogens were futher evaluated. Finally, the main antibacterial components in the extracts were identified by UV-Vis absorption spectroscopy, UPLC-UV spectrum and UPLC-ESI-MS. The results showed that the content of total phenolic was the greatest, and BE has a good inhibitory effect on the growth curve of six foodborne pathogens, and average inhibition zone diameter (IZD) reached 19.5 mm. Furthermore, the four main antimicrobial components, cyanidin 3-O-glucoside, flavonoid deoxy hexacoside, quercetin 3-O-glucoside, and quercetin deoxidized hexacoside, were identified from the BE. Practical applications: Bayberries are important sources of phytochemicals such as phenolic acids, anthocyanins, and flavonol glycosides. Recent findings from our laboratory revealed the BE had a significant bacteriostatic effect. Therefore, this paper investigated the antibacterial activity of BE to 6 common foodborne pathogens, and on this basis further confirmed the effective active components of BE. This study provides an important reference for BE application in food, pharmaceutical and chemical fields.

“…is an edible fruit native to East Asia with popularity for its attractive color and delicious taste, and is also highly valued for its nutritional and medicinal properties ( Ren et al, 2021 , Sun et al, 2013 , Zhang et al, 2022a ). Modern pharmacological studies have proved that bayberry extracts possess multiple biological activities, including antioxidant, anti-inflammatory, anti-diabetic, and anti-cancer effects owing to the presence of various bioactive compounds like vitamins, flavonoids and phenolic acids ( Ju et al, 2018 , Liu et al, 2020 , Lyu et al, 2021 , Tu et al, 2022 , Zhang et al, 2022a ). Due to the extreme perishability of the fresh fruit, the harvested bayberries are often used for processing, in addition to fresh consumption.…”
