Abstract

The invention relates to an identification method for three polygonatum sibiricum with a legal origin. Collected medicinal materials are extracted by utilizing an ultrasonic method; representation isperformed on chemical compositions by utilizing serial connection of ultra-high performance liquid chromatography and electrostatic field orbitrap high resolution mass spectrum (UPLC-Orbitrap MS) technology after an extract solution is purified by a PS/AL solid phase extraction column; and data are analyzed and processed by utilizing multivariate statistical analysis, wherein the multivariate statistical analysis includes principal component analysis (PCA), partial least squares discrimination analysis (PLS-DA), orthogonal corrected partial least square analysis (OPLS-DA), and cluster analysis(HCA). We found that the chemical components of the medicinal materials of three polygonatum sibiricum with the legal origin are significantly different; the constructed analytical method can be usedto distinguish the three polygonatum sibiricum with the legal origin; and research results provide a basis for in-depth study of the medicinal materials of polygonatum sibiricum and scientific formulation with a quality standard.

Description

technical field [0001] The invention relates to the field of identification of traditional Chinese medicines, in particular to the identification of chemical components of Polygonatum. Background technique [0002] Polygonatum was first recorded in the "Famous Doctors" in the Jin Dynasty. It has the functions of nourishing the kidney and essence, nourishing yin and moistening dryness. It is used to nourish and strengthen the body and treat kidney deficiency, dry cough and spleen and stomach weakness. [1] , is one of the commonly used medicines in Chinese medicine. Modern pharmacological studies have proved that Polygonatum has various pharmacological effects such as enhancing immunity, lowering blood fat, blood sugar, and delaying aging. [2] , is an important resource for both medicine and food, and is known as the "King of Blood and Qi Supplement". [3] . [0003] The 2015 edition of "Chinese Pharmacopoeia" stipulates that Polygonatum is derived from the dried rhizomes of...
