埃塞俄比亚欧泊的成分特征分析

2008年在埃塞俄比亚Welo省附近发现了一个新的火山型欧泊矿床,该产地的欧泊具有比较独特的外观。通过激光诱导离解光谱仪、X射线能谱仪、傅里叶红外光谱仪及热重分析测试研究了埃塞俄比亚欧泊样品的成分特征及所含水的存在形式,并与澳大利亚和墨西哥欧泊的成分特征进行了对比研究。研究表明:埃塞俄比亚欧泊含有Si、Ca、Mg、Al、Ba、Fe和Sr等元素,其中Ca、Ba和Sr元素含量总体比澳大利亚欧泊和墨西哥欧泊高,具有一定的产地鉴别意义。埃塞俄比亚欧泊的红外光谱在791cm~(-1)处的吸收峰指示其具有一定的结晶度,此特征与同是火山热液成因的墨西哥欧泊一致,而与风化淋滤成因的澳大利亚欧泊没有明显结晶化的特征不同。热重分析测试结果表明,埃塞俄比亚欧泊中的水以吸附水和结晶水两种形式存在,与其它产地欧泊没有明显差异。

从绿色食品的营销谈概念产品的营销手段

目前，“绿色食品”在百姓中间己不再是一个陌生词汇，它不但进入了百姓的健康话题，而且在某种程度上已经成为一冲饮食时尚，政府有关部门对绿色食品的重视程度和工作力度也越来越大，但在零售业及百姓消费中，绿色食品还停留于一种概念上的认识，离实际的销售及实际的购买还有一段距离根据目前的市场状况，我认为主要有以下几点问题：

An assessment of international strategic merchandising from China,post–quota elimination in January 2005 for the UK apparel market

Abstract

On January 1, 2005, the Multi-Fibre Arrangement, which established quotas on different categories of apparel and textile imports to the European Union, was phased out.This article synthesizes the determinants of trade patterns in the absence of quotas and reviews their impact for the UK apparel retailermarket. It assesses international strategic merchandising from China, post-quota elimination for the UK apparel market with particular reference to global adjustment to apparel supply. However, to sustain their domination of global fashion textile supply, particularly to EU markets, China will need to face the challenges of anti-dumping, technical regulations or standards, preferential trade agreements, regional free trade zones and other non-tariff trading barriers. The article concludes that China is well placed to exploit her position of dominance but suggests that sub-optimal considerations of cost versus response time to the EUretailer will provide a challenge for the future supply of fashion retail products.     

Comparison of structural,antioxidant and immuno‐stimulating activities of polysaccharides from Tremella fuciformis in two different regions of China

In this study, we compared the chemical structure, antioxidant and immuno‐stimulating activities of two polysaccharides, TPS–FJ and TPS–SC, extracted from Tremella fuciformis from two of the major cultivation regions of China. TPS–FJ and TPS–SC contained protein and high uronic acid. Average molecular weights of TPS–FJ and TPS–SC were 45 461 and 25 981 kDa, respectively. A triple‐helix conformation was exhibited by TPS–FJ but not by TPS–SC. TPS–FJ and TPS–SC contained same monosaccharides but in different ratios. Both the polysaccharides displayed characteristic polysaccharide bands in their Fourier transform infrared and NMR spectra, shown high water and oil holding capacity, and retained antioxidant potential after simulated gastrointestinal digestion in vitro. TPS–FJ significantly (P < 0.05) stimulated the nitric oxide, tumour necrosis factor‐α and interleukin‐6 production of RAW 264.7 cells with higher reactions than those of TPS–SC in vitro. Thus, Tremella fuciformis polysaccharide can be used as a potential antioxidant and immunomodulatory ingredient in food industry.     

Comparison of Polyphenol Profile and Inhibitory Activities Against Oxidation and α‐Glucosidase in Mulberry (Genus Morus) Cultivars from China

Mulberry (genus Morus) is a significant source of polyphenols, which can promote positive effects on human health. China has various mulberry cultivars, however, many Chinese mulberry cultivars have been only minimally studied. To solve this lack of research, 8 mulberry cultivars (Da10, Tang10, Yueshen74, Yuefenshen, Longsang, Ningxia1hao, Taiwanguosang, and Baiyuwang) from 4 regions of China were assessed to determine their polyphenol profiles using HPLC‐MS/MS and then tested for their antioxidant and anti‐α‐glucosidase activities in vitro. A total of 18 nonanthocyanins and 4 anthocyanins were quantified in mulberry cultivars; among these polyphenols, chlorogenic acid, quercetin 3‐O‐rutinoside, and cyanidin 3‐O‐glucoside were confirmed as the major phenolic acid, flavonol derivative, and anthocyanin, respectively. Two types of stilbene compounds, piceid, and piceatannol, were detected for the 1st time in all mulberry cultivars. Moreover, the methanolic extracts of different mulberry cultivars showed disparate antioxidant and α‐glucosidase inhibitory activities, and this discrepancy was mainly attributed to varying the anthocyanin content. Based on our results, Taiwanguosang is proposed to be a good candidate suitable for further process due to its high level of anthocyanins.
