This standard applies to the confirmation of the structure of standard samples of marine biological active substances.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Marine bioactive material marinebioactivematerial Marine biological components or metabolites that affect the life activities of humans, animals, plants, and microorganisms, derived from marine organisms or their derivatives Biological and molecular weight less than 1500 Da. 2.2 Structure confirmation structureconfirmation Through physical and chemical methods, the structural process of the target compound is confirmed accurately. 2.3 Spectral analysis Mainly based on optical theory, based on the interaction of matter and light, establish mutual interaction between material molecular structure and electromagnetic radiation. Relationship, thereby performing methods for geometrical isomerization, stereoisomerism, conformational isomerization, and molecular structure analysis and identification of matter molecules. 2.4 Reference referencesubstance A control substance used to identify, inspect, quantify, and calibrate the performance of a calibration instrument. 2.5 Standard sample referencematerial; RM One or more materials that are sufficiently uniform and stable to define characteristics have been determined to meet the intended use of the measurement process. [GB/T 15000.3-2008, definition 3.1] 2.6 Chiral compound chiralcompounds If the composition of a pair of molecules and the arrangement of the atoms are exactly the same, but they are mirror images of each other as in the left and right hands, in three dimensions Do not overlap, the pair of molecules are called chiral isomers, and the chiral isomers are called chiral compounds.

3 structural confirmation

3.1 Structural Confirmation Procedure 3.1.1 General target compounds should be structurally confirmed according to the following procedures. a) Mass spectrometry or high resolution mass spectrometry to determine the molecular weight and molecular formula of the target compound, and derive some structures according to the fragment peak and the cleavage law information; b) the hydrogen spectrum, carbon spectrum and other atomic spectra of the nuclear magnetic resonance spectrum, and the related two-dimensional spectrum to determine the molecular structure of the target compound;
