Antioxidant activity of microwave-assisted extract of longan (Dimocarpus Longan Lour.) peel（微波萃取）
相比于索氏提取，时间更短，产率更高。 Abstract: The longan (Dimocarpus Longan Lour.) peel was extracted with 95% ethanol employing microwave-assisted extraction and Soxhlet extraction method, the total phenolic content of microwave-assisted extract of Langan peel (MEL) and Soxhlet extract of Langan peel (SEL) reached 96.78 mg/g and 90.35 mg/g dry weight, respectively, expressed as pyrocatechol equivalents, which were quanti?ed using Folin–Ciocalteu reagent. Subsequently, antioxidant properties of two extracts were investigated employing various established systems in vitro including 2,20-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, hydroxyl radical scavenging assay using a new resonance scattering (RS) method, reducing power and total antioxidant capacity. MEL and SEL showed excellent antioxidant in all test systems compared to synthetic antioxidant 2,6-di-ter-butyl-4-methylphenol (BHT) and the antioxidant activities of MEL were all superior to those of SEL. Furthermore, the suitability of MEL and SEL as substitute of BHT were determined in peanut oil, and the decrease of lipid oxidation were monitored using thiobarbituric acid-reactive substances (TBARS) assay. MEL and SEL treatment signi?cantly (P < 0.05) reduced lipid oxidation in peanut oil compared to the control. No signi?cant differences (P ? 0:05T in lipid oxidation were detected between MEL, SEL and BHT samples of peanut oil.

Microwave-assisted synthesis nanocomposite for supercapacitor（微波辅助合成纳米材料）
Abstract An organic–inorganic poly(3,4-ethylenedioxy-thiophene) (PEDOT)/RuO2·xH2O nanocomposite (approxi-mately 1 wt.% RuO2) has been successfully prepared for the first time under microwave irradiation within 5 min with power 900 W via in situ chemical polymerization. The morphology and structure of the resultant material is characterized by transmission electron microscope and Fourier transform infrared. Moreover, the electrochemical properties of the synthesized nanocomposite can be controlled by adjusting the annealing temperature, which is definitely illustrated by cyclic voltammetry, galvanostatic charge–discharge, and electrochemical impedance spectra. Electrochemical data have shown that the PEDOT/RuO2·xH2O nanocomposite annealed at 150 °C possesses the most favorable charge/discharge ability with a specific capacitance of 153.3 F g?1at a current density of 150 mA g?1 and the high efficient utilization of PEDOT at various current densities. Furthermore, such composite has a less capacitance degradation of 23.8% after 1,000 continuous cycles. The improved electrochemical performance are mainly attributed to the large electroactive surface of nanocomposite and the existence of amorphous RuO2·xH2O particles as well as a synergistic effect of the polymer PEDOT and annealed RuO2·xH2O. Thus, the PEDOT/RuO2·xH2O nanocomposite annealed at 150 °C can act as a promising electroactive material for supercapacitor application
