Molecular characteristics of Illicium verum extractives to activate acquired immune response

الملخص EN

Illicium verum, whose extractives can activate the demic acquired immune response, is an expensive medicinal plant.

However, the rich extractives in I.

verum biomass were seriously wasted for the inefficient extraction and separation processes.

In order to further utilize the biomedical resources for the good acquired immune response, the four extractives were obtained by SJYB extraction, and then the immunology moleculars of SJYB extractives were identified and analyzed by GC–MS.

The result showed that the first-stage extractives contained 108 components including anethole (40.27%), 4-methoxy-benzaldehyde (4.25%), etc.; the second-stage extractives had 5 components including anethole (84.82%), 2-hydroxy-2-(4-methoxy-phenyl)-n-methyl-acetamide (7.11%), etc.; the third-stage extractives contained one component namely anethole (100%); and the fourth-stage extractives contained 5 components including cyclohexyl-benzene (64.64%), 1-(1- methylethenyl)-3-(1-methylethyl)-benzene (17.17%), etc.

The SJYB extractives of I.

verum biomass had a main retention time between 10 and 20 min what’s more, the SJYB extractives contained many biomedical moleculars, such as anethole, eucalyptol, [1S-(1a,4aa,10ab)]-1,2,3,4,4a,9,10, 10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenecarboxylic acid, stigmast-4-en-3- one, c-sitosterol, and so on.

So the functional analytical results suggested that the SJYB extractives of I.

verum had a function in activating the acquired immune response and a huge potential in biomedicine
