摘要

本文介绍了野生桤木黑叶、灰叶和心叶的商品指标研究数据。测定了所研究样品的水分含量。常见的火山灰。灰分不溶于10%的盐酸溶液,有有机和矿物杂质,部分植物失去了自然颜色。络合滴定法测定了原料中单宁的含量,其含量在4.56 ~ 8.59%之间,可以考虑将这种原料作为植物修复的一个有前途的额外来源。

Comparative assessment of commodity indicators of alder leaves of different types
The article presents data on the study of commodity indicators of black, gray and heart-leaved alder leaves harvested from wild plants. The moisture content was determined for all the studied samples. Common ash. Ash insoluble in a 10% solution of hydrochloric acid, organic and mineral impurities, parts of the plant that have lost their natural color. The complexometric titration method determined the content of tannins in the raw material, the content of which in the amount of 4.56 to 8.59%, allows considering this type of raw material as a promising additional source of phytopreparations.
