“…Among diverse medicinal properties of P. orientalis, antioxidant, antimicrobial, antiseptic, analgesic, antinociceptive, anti-hepatotoxic, anti-inflammatory and anticancer activities are most significant. It is widely used for treatment of dysentery, knee pain, toothache, opthalmia, blepharitis, conjunctivitis, hemorrhage, dermatological and gastrointestinal diseases, kidney stones, itching, rheumatic and inflammatory diseases [20][21][22][23][24]. However, no reports on synthesis of AuNPs and AgNPs using P. orientalis leaf extract (POLE) are available till date.…”

This report details on synthesis of AuNPs and AgNPs using POLE with optimized reaction parameters, for the first time. The bioreduced nanoparticles were characterized using UV-visible spectroscopy, high resolution transmission electron microscopy (HRTEM), energy dispersive spectroscopy (EDS), dynamic light scattering (DLS), X-ray diffraction spectroscopy (XRD), fourier transform infrared (FTIR) spectrometry. Both AuNPs and AgNPs Further we evaluated the catalytic potential of the nanoparticles towards reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) using NaBH 4 . AbstractIn an attempt to synthesize novel catalytic gold (AuNPs) and silver nanoparticles (AgNPs) we have used Platanus orientalis leaf extract for both reduction and capping. The synthesis was rapid which completed by 5 h as indicated by change in colour and development of prominent peak at 540 nm for AuNPs and 440 nm for AgNPs, as revealed by UV-visible spectroscopy. The phytogenic nanoparticles showed exotic shapes which included triangles, spheres, hexagons and pentagons as analyzed by high resolution transmission electron microscopy. The optimized processing parameters like salt concentration (1 mM concentration of HAuCl 4 and 4 mM of AgNO 3 ) and the reaction temperature (50°C) led to faster nanoparticles synthesis. Energy dispersive spectra and X-ray diffraction studies confirmed the elemental gold and silver in AuNPs and AgNPs. Detailed phytochemical characterization using biochemical techniques and gas chromatography mass spectrometry indicated the predominance of ascorbic acid, citric acid, reducing sugars and even starch which may together lead to simultaneous synthesis and capping. Further, AuNPs and AgNPs catalyzed the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) using NaBH 4 with apparent rate constants of 1.908 × 10 -4 min -1 and 3.071 × 10 -4 min -1 , respectively.

“…Platanus orientalis L., a medicinal tree from the family Platanaceae, is one of the largest and longest-lived trees in the Eastern Mediterranean (Hajhashemi et al, 2011;Rix ve Fay, 2017). Anticancer, antiinflammatory and antinociceptive activities of P. orientalis and its effects in asthma, ulcerogenic risk assessment, hoarseness and its use as anti-aging have been reported up to now (Tantry et al, 2012;Haider et al, 2012;Asadbeigi et al, 2014;Chatzigeorgiou et al, 2017). Ethanol have toxic effects on the immune system and nervous system (Brust, 2010;Chardwick and Sisson, 2015).…”

“…Since ancient times, Platanus orientalis has been used as a painkiller against dental pain and knee pain and inflammation in folk medicine (Hajhashemi et al, 2011). Furthermore, the effects of PO infusion and extracts and compounds isolated from PO were investigated in anticancer, anti-inflammatory and antiseptic, oxidative stress, toothache and dermatological and rheumatic diseases or disorders (Tantry et al, 2012;Haider et al, 2012;Shende et al, 2018;Khan, 2017;Dogan and Anuk, 2019).In spite of modern medicine, the use of complementary and alternative medicine is increasing worldwide and many medicinal plants are being used for disease treatment and health improvement (Eardley et al, 2012). In the present study we investigated the effects of P.orinetalis leaf infusion on neurotoxicity and immunotoxicity against ethanol-induced toxicity in rats.…”

In this study, immunotoxic and neurotoxic effects of leaf infusion of Platanus orientalis L. (PO) were investigated in rats ethanol-induced toxicity. Neurotoxic effects of ethanol were evaluated by measuring acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) in rat brain tissue. Immunotoxic effects were evaluated by adenosine deaminase (ADA) and myeloperoxidase (MPO) biomarkers in rat liver, lung, erythrocyte and spleen tissues. Thirty male Wistar rats were divided into five groups after toxicity study.

“…The most general method for the identification and quantification of flavonol glycosides involves a high-performance liquid chromatography (HPLC) system coupled with MS/MS or hybrid mass spectrometry (11)(12)(13) and single mass spectrometry (15)(16)(17). The investigation reports that formation of flavonol glycosides using nuclear magnetic resonance (NMR) (17)(18)(19) has also become a common research topic in recent years. However, the analytical methods using LC/MS, LC/MS/MS, or NMR have not been easily available in some laboratories because of their high cost.…”

An analytical method for the simultaneous determination of 12 flavonol glycosides in buckwheat, black tea, and wild parsley using ultra high-performance liquid chromatography (UHPLC) coupled with a simple liquid extraction method using dimethyl sulfoxide (DMSO) was validated in precision, accuracy, and linearity. The UHPLC separation of target compounds was performed on a C18 column using a photodiode array (PDA) detector and the wavelength was fixed at 350 nm. The recovery values for flavonol glycosides ranged from 85.44 to 108.79%. The limits of detection and limits of quantification were less than 0.32 mg/kg and less than 0.97 mg/kg, respectively. The intraday and interday precisions were less than 13.69% for all the test samples. This method coupled with UHPLCPDA detection could be expected to provide more convenient sample preparation than conventional methods in the tested foods.
