2. Procurement content
| serial number | Goods/service name | Technical/Service Requirements | quantity | unit of measurement | Unit price limit (Yuan) | Remark |
1 | Isolation and structural identification of non-flavonoid trace active ingredients in hawthorn leaf extract (provided by the client) | (1) The client provides hawthorn leaf extract, and performs directional separation and purification according to the retention time specified by the client through HPLC or TLC to obtain monomeric compounds with a purity of more than 98%. (2) The obtained monomer compounds are required not to overlap with the client’s existing hawthorn leaf extract compound library. (3) Use high-resolution mass spectrometry, 1D and 2DNMR to confirm the structure of each monomer compound, and determine the absolute configuration through single crystal or circular dichroism spectroscopy. And provide structure confirmation report and spectrum. (4) Provide more than 100 mg of each monomer compound reference substance. The content of all isolated compounds in the extract was qualitatively and quantitatively detected using external standards. And provide detailed test reports. (5) The compound category does not include the main components of flavonoids, including terpenes, lignins and at least 5 proanthocyanidin polymers (more than 4-mers). (6) Conduct pharmacological activity evaluation (at least 5 models) on each monomer compound and segment as required by the client. | 30 | indivual | 5700 | Provide detailed original experimental records and raw detection data of the experimental process. Ensure that all monomer compounds are obtained from extracts provided by the client. |
