“…Baicalin, wogonoside, and baicalein had good antibacterial property [ 41 – 43 ], which was consistent with the results that Radix Scutellariae had been used to treat antibacterial diseases in clinic [ 44 , 45 ]. Baicalin and baicalein also had potential as therapeutic or supplementary agents for the treatment of breast cancer [ 46 ], and the anticancer properties of Radix Scutellariae could be attributed to its high content of wogonin, baicalein, and baicalin [ 3 ].…”

Scutellariabaicalensis Georgi, an important perennial herb, is widely distributed and used all over the world. The root of S. baicalensis (Radix Scutellaria) is rich in flavonoids with a variety of bioactive effects and is widely used in clinic. The different geographical and climatic conditions of different cultivated areas of S. baicalensis lead to the differences of the main components in Radix Scutellaria. The main objective of this study was to evaluate the difference of flavonoid content in Radix Scutellaria from different cultivated areas in China. The mobile phase system, elution gradient, detection wavelength, and other chromatographic conditions for high-performance liquid chromatography-diode array detection (HPLC-DAD) determination of 8 flavonoids in Radix Scutellaria were optimized. The contents of flavonoids in 38 samples of Radix Scutellaria collected from seven main genuine cultivated areas were determined, and the correlation between the content, cultivated area, and the biological activities of Radix Scutellaria was compared. The results implied that baicalin, wogonoside, and baicalein were the three main flavonoids with the highest contents in Radix Scutellaria. The content of flavonoids in different cultivated areas was very different, which had significant regionality and was closely related to the natural conditions of various places. The antioxidant and antitumor activities of the extract of Radix Scutellaria were closely related to the content of flavonoids, and high contents of baicalin, wogonoside, and baicalein positively improved biological activities.

“…In the process of packaging fruit, the fruit would consume its own organic substance through certain respiration and release carbon dioxide and water inevitably [ 79 , 80 ]. As a result, more or less condensed water would be generated in the closed packaging environment after a certain time, which could be undesirably helpful to the reproduction of microorganisms [ 81 ]. Therefore, the F6 fiber with a certain moisture absorption could effectively eliminate these water droplets to prevent bacterial reproduction and further promote the dissolution and diffusion of resveratrol molecules in the packaging environment.…”

The purpose of this work is to develop a novel ultrathin fibrous membrane with a core-sheath structure as antibacterial food packaging film. Coaxial electrospinning was exploited to create the core-sheath structure, by which the delivery regulation of the active substance was achieved. Resveratrol (RE) and silver nanoparticles (AgNPs) were loaded into electrospun zein/polyethylene oxide ultrathin fibers to ensure a synergistic antibacterial performance. Under the assessments of a scanning electron microscope and transmission electron microscope, the ultrathin fiber was demonstrated to have a fine linear morphology, smooth surface and obvious core-sheath structure. X-ray diffraction and Fourier transform infrared analyses showed that RE and AgNPs coexisted in the ultrathin fibers and had good compatibility with the polymeric matrices. The water contact angle experiments were conducted to evaluate the hydrophilicity and hygroscopicity of the fibers. In vitro dissolution tests revealed that RE was released in a sustained manner. In the antibacterial experiments against Staphylococcus aureus and Escherichia coli, the diameters of the inhibition zone of the fiber were 8.89 ± 0.09 mm and 7.26 ± 0.10 mm, respectively. Finally, cherry tomatoes were selected as the packaging object and packed with fiber films. In a practical application, the fiber films effectively reduced the bacteria and decreased the quality loss of cherry tomatoes, thereby prolonging the fresh-keeping period of cherry tomatoes to 12 days. Following the protocols reported here, many new food packaging films can be similarly developed in the future.

“…CS contained a large number of cations, which can break the negatively charged cell membrane of bacteria and lead to their death. 71 However, this process only occurred when bacteria were exposed to CS for a period of time. 72 Therefore, the antibacterial activity of CS is not immediate, and bacteria may greatly improve their resistance due to the formation of biofilm through their quorum sensing (QS) system.…”

“…Furthermore, when the total amount of CS and Cur was equal, the antibacterial performance of the nanofibrous membrane containing CS and Cur was stronger than that of CS alone and Cur alone. CS contained a large number of cations, which can break the negatively charged cell membrane of bacteria and lead to their death . However, this process only occurred when bacteria were exposed to CS for a period of time .…”

Antibacterial air filtration membranes are essential for personal protection during the pandemic of coronavirus disease 2019 (COVID-19). However, high-efficiency filtration with low pressure drop and effective antibiosis is difficult to achieve. To solve this problem, an innovative electrospinning system with low binding energy and high conductivity was built to enhance the jet splitting, and a fluffy nanofibrous membrane containing numerous ultrafine nanofibers and large quantities of antibacterial agents was achieved, which was fabricated by electrospinning polyamide 6 (PA6), poly(vinyl pyrrolidone) (PVP), chitosan (CS), and curcumin (Cur). The filtration efficiency for 0.3 μm NaCl particles was 99.83%, the pressure drop was 54 Pa, and the quality factor (QF) was up to 0.118 Pa–1. CS and Cur synergistically enhanced the antibacterial performance; the bacteriostatic rates against Escherichia coli and Staphylococcus aureus were 99.5 and 98.9%, respectively. This work will largely promote the application of natural antibacterial agents in the development of high-efficiency, low-resistance air filters for personal protection by manufacturing ultrafine nanofibers with enhanced antibiosis.
