| 1 | Antioxidant and α-glucosidase inhibitor activities of natural compounds isolated from Quercus gilva Blume leaves显示文摘Objective: To isolate and investigate antioxidant and α-glucosidase inhibitor compounds in the leaves of Quercus gilva Blume(Q. gilva).Methods: Dry leaves of Q. gilva were extracted with methanol and the methanolic extract was further separated by silica gel column chromatography using several solvents with increasing polarity. The antioxidant activities of the isolated compounds were evaluated using various in vitro assays: 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, hydrogen peroxide radical scavenging activity, β-carotene bleaching assay, and reducing power assay. The α-glucosidase inhibitory assay was conducted against α-glucosidase from Saccharomyces cerevisiae.Results: Three compounds were isolated and their structures were identii ed as catechin(1), epicatechin(2), and tiliroside(3) using an instrumental analysis. Compound 2 had higher antioxidant activity with inhibitory concentrations(IC50) of(22.55 ± 2.23) μmol/L than that of quercetin, which was used as the standard, with an IC50 of(28.08 ± 2.39) μmol/L, followed by compound 1 with IC50 of(40.86 ± 3.45) μmol/L. On the other hand, compound 3 had the lowest antioxidant activity with an IC50 of(160.24 ± 8.15) μmol/L. However, compound 3 had the highest α-glucosidase inhibitory activity with an IC50 of(28.36 ± 0.11) μmol/L, followed by compounds 1 and 2 with(168.60 ± 5.15) and(920.60 ± 10.10) μmol/L, respectively.Conclusions: The results obtained for the antioxidant activities and α-glucosidase inhibitory activities in a methanolic extract from the leaves of Q. gilva coni rmed the potential of this plant as a source of natural antioxidants and antidiabetic medicine. | Anastasia Wheni Indrianingsih Sanro Tachibana Rizna Triana Dewi Kazutaka Itoh | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，9： | 4 |
| 2 | Western view of the management of gastroesophageal foreign bodies显示文摘The best modality for foreign body removal has beenthe subject of much controversy over the years.We have read with great interest the recent article by Souza Aguiar Municipal Hospital,Rio de Janeiro,Brazil,describing their experience with the management of esophageal foreign bodies in children.Non-endoscopic methods of removing foreign bodies(such as a Foley catheter guided or not by fluoroscopy)have been successfully used at this center.These methods could be an attractive option because of the following advantages:Shorter hospitalization time;easy to perform;no need for anesthesia;avoids esophagoscopy;and lower costs.However,the complications of these procedures can be severe and potentially fatal if not performed correctly,such as bronchoaspiration,perforation,and acute airway obstruction.In addition,it has some disadvantages,such as the inability to directly view the esophagus and the inability to always retrieve foreign bodies.Therefore,in Western countries clinical practice usually recommends endoscopic removal of foreign bodies under direct vision and with airway protection whenever possible. | Aurora Burgos Luis Rábago Paloma Triana | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，9： | 3 |
