摘要：
Bayberry has been largely planted in China, and the waste of fresh flesh of bayberry was still abandoned. Therefore, the extractives of fresh flesh of bayberry were studied to further utilize the bio-resources. Through the Foss method, the result shown that ketone, aldehyde, ester and acid compounds were accounted for 1.30, 92.61, 0.54 and 6.09% of the extractives which were extracted from fresh flesh of bayberry by methanol solvents. Aldehyde, bicyclic sesquiterpenes, acid, ester and alcohol compounds accounted for 53.74, 9.95, 28.49, 6.79 and 1.05% of the extractives which were extracted from fresh flesh of bayberry by ethanol solvents. Ketone, aldehyde, carbohydrate, acid and ester compounds accounted for 4.77, 77.95, 12.06, 4.77 and 0.44% of the extractives which were extracted from fresh flesh of bayberry by ethyl acetate solvents. The extractives of fresh flesh of bayberry were rich in rare drug and biomedical activities and the ethanol is more better to extract the fresh flesh of bayberry. (C) 2017 The Authors.

摘要：
Onions (Allium cepa L.) comprise a valuable vegetable crop in many countries. Modern scientific research has shown that onions possess many biological activities, including antibacterial, anticancer, hypoglycemic, hypolipidemic, antiplatelet aggregation, and antioxidant activities. The goal of this study was to investigate the impact of total onion polyphenols on antioxidant and xanthine oxidase (XO) inhibitory activities. Total onion polyphenols showed significant antioxidant activity in DPPH, FRAP, and OH-assays (IC50 [mg/mL]), 43.24, 560.61, and 12.97, respectively). In a X/XO system, antioxidant properties of these polyphenols significantly inhibited XO activity (IC50 [mu g/mL], 17.36). These results indicated that total onion polyphenols showed promising antioxidant and anti-gout properties and might be used as potential, natural drugs against oxidative diseases after successful studies in vivo as well as clinical trials.

摘要：
Bamboo macromolecules were pretreated with bamboo vinegar, which has an antibacterial property, and processed into antibacterial bioboard (ABB) by hot pressing. The ABB was then analyzed by conducting Fourier-transform infrared spectroscopy, thermogravimetric analysis and differential thermal analysis. Results showed that ABB samples had average density of 1.0 g/cm(3), which is appropriate for application. The physical and mechanical properties were best for the ABB sample pretreated with bamboo vinegar and hot pressed at 165 degrees C for 10 min. Fourier-transform infrared spectroscopy revealed that the optimum conditions for hot pressing were a temperature of 165 degrees C, duration of 10 min, and the addition of bamboo vinegar. Thermogravimetric analysis/differential thermal analysis curves indicated that the thermal degradation of the ABB was less than that of bamboo, revealing that hot pressing increased the thermal stability of ABB samples. Analysis revealed that pretreatment with bamboo vinegar improved the antibacterial property of the ABB. (C) 2017 The Authors.

摘要：
Employing the antibacterial property of industrial bamboo vinegar (IBV) and the photocatalytic degradation of TiO2, bamboo macromolecules were pretreated and processed into nonvolatile and antibacterial bio board (NVABB). The NVABB was then analyzed by conducting Fourier-transform infrared spectroscopy, thermogravimetric analysis and differential thermal analysis. Results show that NVABB samples had average density of 0.96 g/cm(3), which is appropriate for application. In terms of physical and mechanical properties, the best NVABB sample obtained from IBV, TiO2 and bamboo had an IBV pretreatment time of 10 min, 2% TiO2 and 1% bamboo charcoal. Fourier-transform infrared spectroscopy demonstrated that optimum conditions for hot pressing were a temperature of 170 degrees C, duration of 15 min and the addition of IBV and TiO2. Thermogravimetric analysis/differential thermal analysis curves suggest that the thermal degradation of NVABB was less than that of bamboo and that hot pressing obviously increased the thermal stability of HDBB samples. Analysis of the antimicrobial effect revealed that IBV pretreatment improves the antibacterial property of NVABB. (C) 2017 Production and hosting by Elsevier B.V. on behalf of King Saud University.

摘要：
Exposures to particulate matter with a diameter of 2.5 mum or less (PM2.5) may influence the risk of birth defects and make you allergic, which causes serious harm to human health. Bamboo charcoal can adsorb harmful substances,that was of benefitto people's health. In order to figure out the optimal adsorbtion condition and the intrinsic change of bamboo charcoal, five chemicals were adsorbed by bamboo charcoal and were analyzed by FT-IR. The optimal blast time was 80 min of Na2SO3, 100 min of Na2S2O8, 20 min of Na2SO4, 120 min of Fe2(SO4)3 and 60 min or 100 min of S. FT-IR spectra showed that bamboo charcoal had five characteristic peaks of S-S stretch, H2O stretch, O-H stretch, C 000000000000 000000000000 000000000000 111111111111 000000000000 111111111111 000000000000 000000000000 000000000000 O stretch or CC stretch, and NO2 stretch at 3850 cm(-1), 3740 cm(-1), 3430 cm(-1), 1630 cm(-1) and 1530 cm(-1), respectively. For Na2SO3, the peaks at 3850 cm(-1), 3740 cm(-1), 3430 cm(-1), 1630 cm(-1) and 1530 cm(-1) achieved the maximum at 20 min. For Na2S2O8, the peaks at 3850 cm(-1), 3740 cm(-1), 3430 cm(-1) and 1530 cm(-1) achieved the maximum at 40 min. For Na2SO4, the peaks at 3850 cm(-1), 3740 cm(-1) and 1530 cm(-1) achieved the maximum at 40 min. For Fe2(SO4)3, the peaks at 3850 cm(-1), 3740 cm(-1), 1630 cm(-1) and 1530 cm(-1) achieved the maximum at 120 min. For S, the peaks at 3850 cm(-1) and 3740 cm(-1) achieved the maximum at 40 min, the peaks at 1630 cm(-1) and 1530 cm(-1) achieved the maximum at 40 min. It proved that bamboo charcoal could remove sulfur powder from air to restrain sulfur allergies.
