Furthermore, considering that chemical and physical synthesis methods require high energy consumption and cause environmental pollution, plant-mediated green synthesis of NPs has attracted great attention since it provides eco-friendly, biocompatible, and inexpensive solutions. In this present study, plant mediated green synthesis of Iron Oxide (Fe₂O₃), Zinc Oxide (ZnO) and Titanium Dioxide (TiO₂) nanoparticles by using <i>Laurus nobilis</i> leaves (bay leaves) were carried out and their structural properties were characterized by UV visible spectra, Dynamic Light Scattering (DLS), Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). UV spectrum and FTIR analysis exhibited characteristic peaks indicating the presence of the desired NPs, while DLS analysis and TEM images confirmed that synthesized particles are in nano-scale. The potential of nanoparticles as biofertilizer in agricultural uses were assessed by investigating their effects on sunflower growth in hydroponic system. TEM images of the NP applied plant tissues proved the uptake and translocation of NPs from root to leaf. Furthermore, Fe₂O₃, ZnO and TiO₂ NP applications on sunflower up to 5 ppm generally improved physiological growth parameters such as root length, fresh weight and leaf surface area while 20 ppm of Fe₂O₃ and ZnO NPs application cause a significant decrease.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":20148,"journal":{"name":"Physiology and Molecular Biology of Plants","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oken, a multipurpose medicinal herb, has drawn much interest for its therapeutic qualities from both traditional and modern medicine systems. Many active secondary metabolites, such as bufadienolides, triterpenes, phenols, alkaloids, glycosides, lipids, flavonoids, and organic acids, are responsible for the plant's curative properties. <i>B. pinnatum</i> exhibits a noteworthy significance in oncological research by exhibiting its ability to modify numerous pathways, which may suggest a potential anticancer impact. The herb is recommended for treating lithiasis, a common cause of renal failure, due to its effectiveness in dissolving stones and avoiding crystal formation. The plant has a major impact on diabetes, especially type II diabetes. Moreover, the versatility of <i>B. pinnatum</i> extends to its examination in connection to COVID-19. However, caution is warranted, as <i>B. pinnatum</i> has been reported to possess toxicity attributed to the presence of bufadienolides in its metabolic profile. A comprehensive investigation is essential to thoroughly understand and confirm the synthesis of potentially hazardous compounds. This is crucial for minimizing their presence and ensuring the safe consumption of <i>B. pinnatum</i> among diverse populations of organisms. This review highlights the various medical uses of <i>B. pinnatum</i>, including its ability to effectively treat kidney and liver diseases, as well as its anti-leishmanial, neuropharmacological, antibacterial, immunosuppressive, anti-tumour, and cytotoxic effects.
