| 中文摘要: |
| 以经大孔树脂纯化的美藤果壳酚类物质为原料，用预制硅胶板薄层层析法将其粗分为4个条带，富集各个条带中的物质后使用UPLC-PDA-MS检测，确定其中的酚类物质为：1号条带中有香草酸己糖苷，1，2-芥子酰阿魏酸酰龙胆二糖（待定），矢车菊素3-（6″-阿魏酰槐糖苷）-5-葡糖苷，锦葵花色素3-葡萄糖苷，锦葵花色素3-葡萄糖苷二倍体；2号条带中有香草酸己糖苷，香草酸己糖苷三倍体以及香草酸己糖苷二倍体；3号条带中有对羟基苯甲酸，羟基苯甲酸己糖苷，对香豆酸己糖苷以及对香豆酸四倍体；4号条带中有对羟基苯甲酸以及对香豆酸。 |
| 英文摘要: |
| The phenolic compounds from Sacha Inchi shells purified by macroporous resin were divided into four bands by preparative thin layer chromatography. Then UPLC-PDA-MS was used to analyze the compounds in every band after enrichment. The structures of phenolic compounds were identified as follows: vanillic acid hexoside, 1,2-disinapoyl-feruloyl-gentiobiose (undecided), cyanidin 3-(6″-feruloylsophoroside)-5-glucoside, malvidin 3-glucoside and malvidin 3-glucoside dimer in band 1; vanillic acid hexoside, vanillic acid hexoside trimer and vanillic acid hexoside dimer in band 2; p-hydroxybenzoic acid, hydroxybenzoic acid hexoside, p-coumaroyl hexose and p-coumaric acid tetramer in band 3; p-hydroxybenzoic acid and p-coumaric acid in band 4. |
