Electrochemical Determination of Glycoalkaloids Using a Carbon Nanotubes-Phenylboronic Acid Modified Glassy Carbon Electrode

Abstract: A versatile strategy for electrochemical determination of glycoalkaloids (GAs) was developed by using a carbon nanotubes-phenylboronic acid (CNTs-PBA) modified glassy carbon electrode. PBA reacts with α-solanine and α-chaconine to form a cyclic ester, which could be utilized to detect GAs. This method allowed GA detection from 1 μM to 28 μM and the detection limit was 0.3 μM. Affinity interaction of GAs and immobilized PBA caused an essential change of the peak current. The CNT-PBA modified electrodes were sen… Show more

“…In order to take advantage of this, Xiong and co-workers prepared carbon nanotube-phenylboronic acid (CNTs-PBA) modified glassy carbon electrodes to detect glycoalkaloids using differential pulse voltammetry. 46 After the interaction with a-solanine, the peak current enhanced with a linear response to the a-solanine concentration (Fig. 17).…”

“…Depolama işlemi patates yumrularında ağırlık ve kalite kayıplarının yanı sıra glikoalkaloid birikimine neden olabilmektedir. Marfona ve Granola patates çeşitlerinde toplam glikoalkaloid seviyelerinin depolama süresince sırasıyla 0,42-17,98 mg/kg ve 92-32,76 mg/kg arasında değiştiği ve SGA seviyesindeki en fazla Şekil 1. α-Solanin ve α-Çakonin Yapısı (Wang et al, 2013) artışın aydınlık koşullarda depolanan patateslerde olduğunu bildirilmiştir (Şengül, 2002). Farklı süre ve şekillerde depolanan Agria ve Bettina patates çeşitlerinde toplam glikoalkaloid miktarının depolama önce sırasyla 7,50 ve 8,53 mg/kg olduğu, bu değerlerin 56 günlük depo devresi sonunda dolaylı güneş ışığı koşullarında 120,32 ve 119,12 mg/kg, oda sıcaklığında karanlık koşullarda 49,19 ve 116,31 mg/kg, karanlık buzdolabı koşullarında 52,03 ve 76,09 mg/kg, floresan + led ışık koşullarında ise 94,81 ve 234,31 mg/kg'a yükseldiği bildirilmiştir (Kasnak & Artık, 2018).…”
