摘要
为探究地理标志产品兰州百合(Lilium davidii var.unicolor)的植物化学成分,以甘肃省五个主要产区(兰州市榆中县、兰州市七里河区、定西市临洮县、定西市渭源县、临夏市永靖县)的兰州百合鳞茎为研究对象,基于超高效液相色谱串联四极杆飞行时间质谱法的非靶向代谢组学技术鉴定其植物化学成分.结果表明,在兰州百合鳞茎中初步鉴定出 62种植物化学成分,包含谷胱甘肽等 22种氨基酸、多肽及其衍生物,溶血磷脂酰胆碱等9种油脂和磷脂类,鼠李糖等 7种糖类,阿魏酸、咖啡酸等 7种酚酸类,山奈酚等 4种黄酮类,核黄素、维生素C等 4种天然维生素,阿魏酰腐胺等 3种酚胺类,大丁苷等 2种香豆素类,葫芦巴碱等 2种生物碱,萜类组分松香酸和三萜皂苷类组分刺五加苷E.本研究丰富了兰州百合植物化学成分的现有数据,为兰州百合的研究与利用提供了科学依据.
Abstract
To explore the profiles of phytochemical components in geographical indication product of China Lilium davidii var.unicolor,the bulbs of which derived from five major producing areas of Gansu Province(Yuzhong County,Lanzhou City,Qilihe District,Lanzhou City,Lintao County,Dingxi City,Weiyuan County,Dingxi City,Yongjing County,Linxia City)were detected using ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UHPLC-QTOF MS).Based on untargeted metabolomics technology,a total of 62 phytochemical components were putatively annotated in the bulbs of L.davidii var.unicolor.Among them,there were 22 kinds of amino acids,pept-ides and their derivatives(e.g.,glutathione),9 kinds of lipids and phospholipids(e.g.,lyso-phosphatidylcholin),7 kinds of saccharides(e.g.,rhamnose),7 kinds of phenolic acids(e.g.,ferulic acid and caffeic acid),4 kinds of flavonoids(e.g.,kaem-pferol),4 kinds of natural vitamins(e.g.,riboflavin and vitamin C),3 kinds of phenolamines(e.g.,feruloyl putrescine),2 kinds of coumarins(e.g.,gerberinside),2 kinds of alkaloids(e.g.,trigonelline),terpenoids(e.g.,abietic acid)and trite-rpenoid saponins(e.g.,eleutheroside E).The study would provide richer data and scientific evidence for the investigation and utilization of L.davidii var.unicolor.
