Asian Pacific Journal of Tropical Medicine 2017年第6期10卷 619-626页

作者： Nguyen Thuy Duong Pham Duc Vinh Phuong Thien thuong Nguyen Thi Hoai Le Nguyen thanh Tran The Bach Nguyen Hai Nam Nguyen Hoang Anh Department of Pharmacology Hanoi University of Pharmacy Department of Pharmaceutical Analysis and Standardization National Institute of Medicinal Materials Department of Pharmacognosy Hue University of Medicine and Pharmacy Institute of Marine Biochemistry Vietnam Academy of Science and Technology Institute of Ecology and Biological Resources Vietnam Academy of Science and Technology Department of Medicinal Chemistry Hanoi University of Pharmacy

Objective: To screen Vietnamese medicinal plants for xanthine oxidase(XO) inhibitory activity and to isolate XO inhibitor(s) from the most active plant. Methods: The plants materials were extracted by methanol. The active plant materials were fractionated using different organic solvents, including n-hexane, ethyl acetate, and n-butanol. Bioassay-guided fractionation and column chromatography were used to isolate compounds. The compounds structures were elucidated by analysis of spectroscopic data, including IR, MS, and NMR. Results: Three hundreds and eleven methanol extracts(CME) belonging to 301 Vietnamese herbs were screened for XO inhibitory activity. Among these plants, 57 extracts displayed XO inhibitory activity at 100 μg/m L with inhibition rates of over 50%. The extracts of Archidendron clypearia, Smilax poilanei, Linociera ramiflora and Passiflora foetida exhibited the greatest potency with IC_(50) values below 30 μg/m L. Chemical study performed on the extract of Archidendron clypearia resulted in the isolation of six compounds, including 1-octacosanol, docosenoic acid, daucosterol, methyl gallate, quercitrin and(-)-7-O-galloyltricetiflavan. The compound(-)-7-O-galloyltricetiflavan showed the most potent XO inhibitory activity with an IC_(50) value of 25.5 μmol/L. Conclusions: From this investigation, four Vietnamese medicinal plants were identified to have XO inhibitory effects with IC_(50) values of the methanol extracts below 30 μg/m L. Compound(-)-7-O-galloyltricetiflavan was identified as an XO inhibitor from Archidendron clypearia with IC_(50) value of 25.5 μmol/L.

水是保障人类生产生存的必需资源,临水而居是人类文明中最智慧的选择。随着经济发展,城市扩张,现代都市中最具活力的区域仍然是滨水区域。越南是滨水国家,主要大中城市都位于滨海和滨水区域,因此越南城市滨水区的景观更新是人们关注的焦点。论文在对大量城市滨水区景观案例分析的基础上,结合越南城市滨水区快速发展的具体国情,对城市滨水区景观更新的设计途径进行了深入的研究探索。论文将研究范围定位为城市滨水区景观更新设计,并将景观环境的营造作为研究的重点。在对中国城市滨水区发展策略和国外滨水景观相关理论发展趋势研究的基础上,辨析了城市滨水地区景观环境更新提升的诱导因素,形成对滨水地区景观更新设计的总体认识。中国与越南一衣带水,同为社会主义发展中国家,城市的发展策略也具有较多相似性,从中国城市滨水区复兴中的成功经验和教训,可以得出越南未来城市滨水区更新发展道路中的矛盾和问题,从中得到启发。论文从国际视角出发,城市滨水景观空间的更新如何结合自然、城市脉络、城市活力、城市功能等四个方面,全面阐述了如何融入城市和走向场所的景观更新模式与思路。论文针对城市滨水地区景观空间的更新路径,从城市滨水地区的空间形态与景观规划、景观空间组织策略、空间更新构成要素、滨水景观更新设计路径等几个方面,论述了越南城市滨水区景观设计要素的特点和营造方法,以及各要素协调发展的滨水景观生成途径。文章的最后,以胡志明市THUTHIEM地区提出越南滨水地区景观空间更新的策略与途径,包括项目概况、规划策略与项目策划、景观空间组成分析、景观空间特色设计等内容,将上文所构建起的更新设计理论通过一个实际的案例,更清晰的表达出来,以期望对越南未来城市滨水区的规划发展,起到借鉴意义。
