摘要:

为探究不同品种的黑老虎果籽的脂质含量及差异,本研究采用广泛靶向代谢组学技术鉴定并分析了虎绿、大红和粉红黑老虎果籽间脂质组分差异和高度富集成分。结果表明,总脂质含量表现为1组(虎绿果籽)>2组(大红果籽)>3组(粉红果籽),脂质成分包括1个游离脂肪酸(free fatty acids,FFA)、3种甘油脂、13种甘油磷脂、4种鞘脂及2种固醇脂等,其中甘油三酯含量最高;比较3组果籽间脂质差异高达172个,其中二酰基甘油-3-O-羧基羟甲基胆碱、二酰基甘油三甲基高丝氨酸及溶血磷脂酰肌醇脂质含量差异尤为显著;比较3组与1、2组间的差异脂质种类,甘油磷脂的数量最多;1组与2组间比较,差异脂质种类中游离脂肪酸的数量最多;进一步通过富集分析发现,黑老虎果籽组间的差异脂质主要富集在以下几条代谢通路中:甘油磷脂代谢、花生四烯酸代谢、亚油酸代谢、脂肪酸生物合成、不饱和脂肪酸生物合成及鞘脂代谢等。不同品种黑老虎果籽的脂质类组分,含量及代谢通路方面具有显著差异,揭示不同品种黑老虎果籽的环境逆境适应能力及潜在功能特性。

Abstract:

To explore the lipid contents and differences of Kadsura coccinea seeds of different varieties, the differences in lipid components and highly enriched components among the Tiger Green seeds, Bright Red seeds and Pink seeds of Kadsura coccinea varieties were identified and analyzed by the widely targeted metabolomics technology in the study. The results showed that the total lipid content was as follows: group 1 (tiger green seeds)>group 2 (bright red seeds)>group 3 (pink seeds). The lipid components included one of free fatty acids , three kinds of glycerolipids, thirteen kinds of glycerophospholipids, four kinds of sphingolipids, two kinds of sterol esters and others, among which the content of triglyceride was the highest. There were one hundred and seventy two lipid differences among the seeds of the three groups. The lipid content differences of 2-[2-[(Z)-hexadec-9-enoyl]oxy-3-tetradecanoyloxypropoxy]-2-[2-(trimethylazaniumyl)ethoxy]acetate,1,2-dipalmitoyl-sn-glycero-3-O-4'-(N,N,N-trimethyl)-homoserine and lysophosphatidylinositol were particularly significant. group 3 was compared with group 1 and group 2 respectively, the number of glycerophospholipids was the largest. As for the comparison between group 1 and group 2, the free fatty acids had the largest number among the types of differential lipids. Further analysis through enrichment revealed that the differential lipids among the groups of K. coccinea seeds were mainly enriched in the following metabolic pathways: glycerophospholipid metabolism, arachidonic acid metabolism, linoleic acid metabolism, fatty acid biosynthesis, unsaturated fatty acid biosynthesis and sphingolipid metabolism and others. The seeds of different varieties of K. coccinea have significant differences in lipid components, contents and metabolic pathways, to reveal the environmental stress adaptation ability and potential functional characteristics of different varieties of seeds.
