Abstract

Samples of coal and peat of different ages from the deposits of Belarus were first studied for the content of plant steroid hormones (brassinosteroids) using independent methods of enzyme immunoassay and HPLC-MS/MS. The quantitative determination of brassinosteroids showed that all the studied samples contained phytohormones of the main natural groups (brassinolide, 24-epibrassinolide, and 28-homobrassinolide), except for brassinolide in the oldest sample. The measured content of brassinosteroids corresponded to that characteristic of modern plant objects, and the composition of brassinosteroids varied depending on the depth of occurrence and other factors. The data obtained may indicate a high stability of plant steroid hormones and their supposed role as bioregulators over a long period of plant evolution.

煤沉积物中的类固醇激素：古代植物与现代植物之间的地球化学桥梁

摘要

首先使用独立的酶免疫法和HPLC-MS / MS方法研究了白俄罗斯矿床中不同年龄的煤和泥炭样品中植物类固醇激素（油菜素类固醇）的含量。油菜素类固醇的定量测定表明，除最老样品中的油菜素内酯外，所有研究样品均包含主要天然组（植物油素，内酯，二十二油菜素内酯和28-同油菜素内酯）的植物激素。测得的油菜素固醇含量与现代植物物体的特征相对应，油菜素固醇的组成随发生深度和其他因素而变化。获得的数据可能表明植物类固醇激素具有很高的稳定性，并且在长期的植物进化过程中，它们应作为生物调节剂发挥作用。
