川渝两地吴茱萸的有效成分测定分析

建立同时测定吴茱萸中吴茱萸碱、吴茱萸次碱和柠檬苦素含量的高效液相色谱的新方法,以测定川渝两地吴茱萸有效成分的含量.采用色谱柱Zorbax Eclipse C<,18>(4.6mm×250mm,5μm),流动相为乙腈-四氢呋喃-0.02%磷酸水溶液(22:13:65)1.0mL/min,检测波长220nm,柱温35℃进行测定.结果表明,吴茱萸碱、吴茱萸次碱和柠檬苦素分别在0.051-0.518μg(r=0.9997)、0.021-0.212μg(r=0.9995)、0.085-0.427μg(r=0.9998)范围内呈良好的线形关系.川渝两地吴茱萸总碱的平均值为1.340%,柠檬苦素含量的平均值为0.4138%,吴茱萸、柠檬苦素含量不能达到药典要求.

THE INDUSTRIAL ECONOMICS OF COPPER PROCESSING

Developing countries have increased their activity in smelting and refining of copper in order to retain a greater proportion of the value added and to achieve more control over production and marketing. This article examines the technology and economics of copper smelting and refining and considers the advantages and disadvantages to developing countries of increased investment in copper ore processing.
Les pays en développement ont accru leur activité dans le domaine de la fonte et du raffinage du cuivre dans le but de conserver une part plus grande de la valeur ajoutée et d'établir un contrôle plus efficace sur la production et la commercialisation de cette ressource. Cet article étudie les aspects techniques et économiques de la fonte et du raffinage du cuivre. Il compare les avantages et désavantages, pour les pays en développement, de la croissance des investissements dans le traitement du minerai de cuivre.

Rehabilitation of degraded tropical forest lands

Summary The area of tropical forest lands in high rainfall areas that is already degraded is great and growing rapidly. Rehabilitation of such lands is important so their biological productivity can support people and reduce pressures for degradation of additional tropical forest lands. While further knowledge and experience is needed, there is a sufficient basis for trial programs. The economic and social well-being is far better served by focusing on rehabilitation of degraded lands than by additional incursions into dwindling stocks of natural forest.This position paper emanated from a Workshop of the IUCN Commission on Ecology at the Forest Research Institute, Kepong, Selangor, Malaysia, 29–31 August 1983, supported by the United 0ations Environment Programme (UNEP). Its publication was made possible by the Independent Commission on International Humanitarian Issues (ICIHI) in the context of its work on deforestation.The following persons participated: Dr. Th. E.
