Abstract

The invention uses Ligusticum chuanxiong volatile oil as a research object, and identifies 13 chemical components related to blood vessel activities (sabinene, gamma-terpinene, terpinolene, (-)-4-terpineol, 4-vinylguaiacol, alpha-selinene, (-)-spainulenol, (+)-spainulenol, 4-iodoindoline, n-butylidenephthalide, N-acetylphenylhydrazine, 4,5-dihydro-3-butylphthalide, and ligustilide), wherein ligustilide, 4,5-dihydro-3-butylphthalide, n-butylidenephthalide and (-)-4-terpineol are main components with blood vessel dilating effect in Ligusticum chuanxiong volatile oil. The identification method comprises the following steps: extracting volatile oil by steam distillation, analyzing chemical components of the volatile oil with GC-MS (gas chromatography-mass spectroscopy), detecting blood vessel dilating activity of the volatile oil, constructing a mathematical model between Ligusticum chuanxiong volatile oil chemical components and blood vessel dilating activity using data mining methods (LARS (least-angle regression) and LASSO (leastabsolute shrinkage and selection operator) regression algorithms), and analyzing the correlation between the components and the blood vessel dilating activity. The blood vessel dilating effective ingredients of the invention can be used for preparing blood vessel dilating medicines.

Description

technical field

[0001] The invention relates to the field of research and development of new traditional Chinese medicines, in particular to the identification of active ingredients of traditional Chinese medicines. Specifically, taking the volatile oil of Rhizoma Chuanxiong as the research object, the active ingredients were screened through data mining to provide technical support for the design of traditional Chinese medicine prescriptions and the optimization of the production process. Background technique

[0002] For a long time, compound prescriptions have been the main form of clinical application of traditional Chinese medicine. The composition of traditional Chinese medicine compound is determined according to the theory of traditional Chinese medicine and combined with the specific syndrome type of the patient. It has rich connotation and theoretical basis, and it is not a simple addition of single-flavored decoction pieces. However, the current research and deve...
