“…[29] The mixture was mixed thoroughly and the garlic-water mixture was enzymatically digested in a water bath at 50 °C. [18] Vapor Distillation of GEO Garlic bulbs (5 kg) were mixed with ionized water (2 L) and blended using a wall breaker for three minutes to obtain garlic paste. The paste was then transferred to a reaction vessel as shown on the left side of Figure S1 and diluted with eight liters of deionized water.…”

“…This study aimed to describe a method for enzymatic hydrolysis of garlic water to propose an efficient method of essential oil extraction and to investigate that garlic oil and its major components can be used for ecologically friendly control of phytopathogenic fungal infestations to achieve the goal of clean, green and safe agriculture. [17] The process of isolating GEO involved distillation, [18] and gas chromatography-mass spectrometry (GC-MS) was utilized to identify the compounds present in the oil, and the primary chemical constituents were isolated by means of vacuum fractionation equipment. In this study, the antifungal activity of garlic essential oil (GEO) was evaluated through in vitro antifungal assays, the antifungal effects were elucidated by structure-activity relationship analysis, scanning electron microscopy (SEM) observation, in vivo experiments, and cellular leakage to explore the potential mechanism of inhibitory effects.…”

Garlic oil has a wide range of biological activities, and its broad‐spectrum activity against phytopathogenic fungi still has the potential to be explored. In this study, enzymatic treatment of garlic resulted in an increase of approximately 50 % in the yield of essential oil, a feasible GC‐MS analytical program for garlic oil was provided. Vacuum fractionation of the volatile oil and determination of its inhibitory activity against 10 fungi demonstrated that garlic oil has good antifungal activity. The antifungal activity levels were ranked as diallyl trisulfide (S‐3)>diallyl disulfide (S‐2)>diallyl monosulfide (S‐1), with an EC50 value of S‐3 against Botrytis cinerea reached 8.16 mg/L. Following the structural modification of compound S‐3, a series of derivatives, including compounds S‐4~7, were synthesized and screened for their antifungal activity. The findings unequivocally demonstrated that the compound dimethyl trisulfide (S‐4) exhibited exceptional antifungal activity. The EC50 of S‐4 against Sclerotinia sclerotiorum reached 6.83 mg/L. SEM, In vivo experiments, and changes in mycelial nucleic acids, soluble proteins and soluble sugar leakage further confirmed its antifungal activity. The study indicated that the trisulfide bond structure was the key to good antifungal activity, which can be developed into a new type of green plant‐derived fungicide for plant protection.

“…The emergence of HTÀ Ag hybrid material has helped discover many applications in life such as resistance to harmful microorganisms such as Escherichia coli, Staphylococcus aureus, antibiotic resistance bacteria, etc. [23][24][25][26]31] At the same time, it is applied in catalysis and adsorption to speed up the oxidation and decomposition of toxic organic substances. [27][28][29][30] Up to now, the deep investigation related to the antibacterial ability of green synthesis HTÀ Ag, especially, against antibiotic resistance bacteria has still been limited in reports.…”

This work aimed to assess the effect of Syzygium nervosum leaf extract as a reducing agent for green synthesis of AgNPs on HT through an optimizing process using response surface methodology (RSM) and the Box‐Benken model. The optimal conditions for synthesis of AgNPs on HT include reaction time of 6.15 hours, reaction temperature of 50 oC and the ratio of diluted Syzygium nervosum leaf extract to reduce AgNO3 of 50.37 mL/mg. Under the optimal conditions, the yield of reduction reaction reached 77.54 %, close to the theoretical value of 76.97 %. Besides, the morphology, density, and characteristics of AgNPs on the surface of HT layers have been determined by using Ultraviolet‐visible spectroscopy, Field emission scanning electron microscopy, High resolution transmission electron microscopy, selected area diffraction, X‐ray diffraction, Dynamic light scattering, Infrared spectroscopy, Fluorescence emission spectroscopy, Brunauer‐Emmett‐Teller methods. The spherical AgNPs were synthesized successfully on the surface of HT with the average particle size of 13.0 ± 1.1 nm. Interestingly, HT‐Ag hybrid materials can inhibit strongly the growth of E. coli, S. aureus as well as two antibiotic resistance bacterial strains, P. stutzeri B27 and antibiotic resistance E. coli. Overall, the HT‐Ag hybrid materials are very promising for application in practice.
