Research ArticleOpen accessIn the author namesPreparing and Antimicrobial Activity of Hydrogel with Biosynthesized Silver Nanoparticles Using Carex Meyeriana KunthQihui Shen, Henan Zhu, Hongli Zhou et al.In this study, a simple and environmentally stable method was developed to synthesize silver Nanoparticles (AgNPs). In addition, carex meyeriana kunth was used as a reducing and stabilizing agent with good bacterial inhibitory effects against Escherichia coli (E. coli) and Bacillus subtilis at very low doses. AgNPs were added to the Polyvinyl Alcohol (PVA) solution as an antibacterial agent and … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 2 · 4 May 2023 · 5,724 accessesView PDFCite
Research ArticleOpen accessIn the author namesStudy on the Polyploidy Induction of Herbicides on Hengshan Astragalus MembranaceusJianxia Liu, Yanmao Gao, Lizhen Liu et al.Studying medicinal polyploid plants is of great significance for the cultivation of traditional Chinese medicine varieties and the extraction of active ingredients. The polyploidization of A. membranaceus (Astragalus membranaceus) was induced using two treatment methods: oryzalin and pendimethalin as mutagens. The results showed that in the same method, the induction effect of polyploidy was affected by the concentration of reagents … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 14 Apr 2026 · 1,535 accessesView PDFCite
Research ArticleOpen accessIn the author namesUltrasonic Microwave Assisted Extraction, Chemical Characterization and Antioxidant Activity of Polysaccharides from Fig LeavesBaikangzhe Zheng, Yang Miao, Yi Zhou et al.This study employed ultrasonic-microwave-assisted extraction (UMAE) to isolate water-soluble polysaccharides from fig (Ficus carica L.) leaves (FLPs). Polysaccharide yield was used as the primary index to evaluate extraction efficiency. The effects of material-liquid ratio, microwave power, extraction temperature, and extraction time on polysaccharide yield were systematically investigated through single-factor experiments, followed by response surface methodology optimization. Structural characterization and antioxidant … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 3 Mar 2026 · 1,671 accessesView PDFCite
Research ArticleOpen accessIn the author namesOptimization of Hydrodistillation Extraction by Response Surface Methodology and Evaluation of the Antioxidant and Antimicrobial Activities of Essential Oils from Phragmites communis (Cav) TrinXin-Tong Zou, Hong-Yuan Ma, Yu-He Li et al.The principal objectives of this study encompass three distinct aspects: firstly, to streamline the extraction process of Phragmites communis (Cav) Trin essential oil; secondly, to systematically analyze the essential oil’s chemical composition; and finally, to evaluate biological activity. Through the system optimization experiment, the optimal extraction process was determined: the crushing size was set to 10 mesh, the total solid-liquid … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 6 Jan 2026 · 2,315 accessesView PDFCite
Research ArticleOpen accessIn the author namesClassification and Spatial Distribution of Macronutrients and Micronutrients in the Soil of Greenhouse Sweet CherriesLijin Qin, Qingxiang Wang, Yongli Lv et al.To understand the distribution of trace elements in the soil of greenhouse sweet cherry, using soil samples from solar greenhouse sweet cherry orchards in Chifeng, Inner Mongolia as the object, the trace element indicators in the soil of different sweet cherry production areas were analyzed using the "S" shaped 5-point sampling method. Descriptive statistics were conducted. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 9 Oct 2025 · 2,174 accessesView PDFCite
