Abstract

Over 40 higher plant species were examined for the contents of total lipids, phospholipids, diacylglyceryl-N,N,N-trimethylhomoserine (DGTS), phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylglycerol (PG) by using micro-HPTLC. The results showed a wider range of plants containing betaine lipids. So, DGTS was found in some higher plant species, not studied earlier, belonging to Equisetophyta, Polypodiophyta; the lipid composition of many other species from Spermatophyta was also studied. It was demonstrated that more primitive plant species contained, as a rule, the betaine lipid DGTS. The quantitative data for the distribution of the main phospholipid classes PC, PE, and PG in various plant species and their tissues are given in this paper.

摘要

通过使用微量高效薄层层析法（micro-HPTLC），对40多种高等植物物种的总脂质、磷脂、二酰基甘油-N,N,N-三甲基高丝氨酸（DGTS）、磷脂酰胆碱（PC）、磷脂酰乙醇胺（PE）和磷脂酰甘油（PG）含量进行了检测。结果表明，含有甜菜碱脂质的植物种类范围更广。因此，在一些之前未研究过的属于木贼纲、蕨纲的高等植物物种中发现了DGTS；还研究了种子植物门许多其他物种的脂质组成。结果表明，通常较原始的植物物种含有甜菜碱脂质DGTS。本文给出了各种植物物种及其组织中主要磷脂类别PC、PE和PG分布的定量数据。
