The constituent and fatty-acid compositions of neutral lipids (NL), glyco-, and phospholipids and the squalene contents in seeds and the aerial part of Amaranthus retroflexus were studied for the first time. Elaidic acid was observed in all lipid groups. The squalene content was 4.3% of the NL mass in seeds and 3.15% in the aerial part. Preliminary wetting of wheat and cucumber seeds in unsaponified substances, fatty acids, and their methyl esters obtained from A. retroflexus seeds at concentrations 0.001 and 0.0001% was found to reduce the inhibiting action of salt stress. Neutral lipids did not exhibit a protective effect.

苋菜的脂质及其生物活性

首次研究了反枝苋种子和地上部分的中性脂质（NL）、糖脂和磷脂的成分和脂肪酸组成以及角鲨烯含量。在所有脂质组中均观察到反油酸。种子中角鲨烯含量为 NL 质量的 4.3%，地上部分为 3.15%。小麦和黄瓜种子在未皂化物质、脂肪酸及其甲基酯中的初步润湿被发现，从 A.retroflexus 种子中获得的浓度为 0.001 和 0.0001% 会降低盐胁迫的抑制作用。中性脂质没有表现出保护作用。
