Abstract

The invention discloses a method for establishing the HPLC fingerprint of a Liubanhong garlic enzymatic hydrolysis product. The method concretely comprises the following steps: carrying out solid phase extraction on bulbs of Liubanhong garlic which is a special kind in Baodi to prepare a test article solution, and carrying out high performance liquid chromatography analysis detection under certain conditions to obtain the HPLC fingerprint of the Liubanhong garlic enzymatic hydrolysis product. A standard fingerprint is obtained by determining common characteristic peaks HPLC fingerprint analysis of 10 batches of samples. The standard fingerprint can provide reliable bases for discrimination of the kind and the producing area of the Liubanhong garlic and production quality control. The method has the advantages of convenient operation, high stability, strong specificity, good reappearance, many characteristic peaks, high analysis efficiency, true and false and producing area discrimination of the Liubanhong garlic, and comprehensive, accurate and effective evaluation of the internal quality of the Liubanhong garlic.

Description

[0001] The invention was funded by the "Key Project of Tianjin Agricultural Commission (201302030) and the Application Development Research Fund of Tianjin Normal University". technical field [0002] The invention belongs to the technical field of natural plant analysis, and relates to a method for constructing natural plant fingerprints, in particular to a method for constructing high-performance liquid chromatography (HPLC) fingerprints of Baodi "six petals red" garlic and standard fingerprints thereof. Background technique [0003] garlic( Allium sativum L. ) Liliaceae Allium, biennial herbaceous plant, food and medicine, is widely planted in the world. At present, my country is the largest garlic producer, with 692,000 hectares of garlic planted in China, accounting for about 1 / 2 of the world's planting area. The total output of garlic in my country accounts for more than 3 / 4 of the world's total output, with an output of 12.088 million tons. As an indispensable vegeta...
