摘要
摘要 这项工作的目的是从冬小麦 Triticum aestivum L.切除的叶片中制备一种富含叶绿素锌衍生物的制剂。首先对叶绿素进行叶绿素化，然后在 р 3.5-4.0 温度下加入 EDTA-Na 冲洗叶片中的酚类化合物和 Mg2+，再加入 ZnCl2 培养；叶片干燥后在黑暗中保存。用乙醇进行双重处理，提取锌衍生物。为了提高产量，重复进行了金属化处理。根据光谱荧光分析和薄层色谱法的结果，所获得的制剂与叶绿素锌 a 和 b 相符。
Production of Preparation Rich in Zn-Pheophytin from the Leaves of Wheat Triticum aestivum L.
Abstract
The aim of this work was to produce a preparation enriched in a zinc derivative of pheophytin from the excised leaves of winter wheat Triticum aestivum L. First, pheophytinization of chlorophyll was conducted, then phenolic compounds and Mg2+ were washed out from the leaves at рН 3.5–4.0 with the addition of EDTA-Na followed by incubation with ZnCl2; the leaves were dried and stored in the dark. Zinc derivatives were extracted by a double treatment with ethanol. In order to improve the yield, metallization was repeated. By the results of spectrofluorimetric analysis and thin-layer chromatography, the obtained preparation corresponded to Zn-pheophytin а and b. Prospects of application of Zn-pheophytin preparation with antioxidant and antiviral activities are discussed.
期刊介绍：
Russian Journal of Plant Physiology is a leading journal in phytophysiology. It embraces the full spectrum of plant physiology and brings together the related aspects of biophysics, biochemistry, cytology, anatomy, genetics, etc. The journal publishes experimental and theoretical articles, reviews, short communications, and descriptions of new methods. Some issues cover special problems of plant physiology, thus presenting collections of articles and providing information in rapidly growing fields. The editorial board is highly interested in publishing research from all countries and accepts manuscripts in English.
