Abstract

The invention discloses an establishment method of an HPLC (High Performance Liquid Chromatography) fingerprint spectrum of an allinase inactivated extract of six-peal red garlics. The establishment method comprises the following specific steps of preparing six-peal red bulbs which belong to a peculiar variety in Baodi County into a test product solution by a solid-phase extraction step and the like; performing HPLC detection under certain conditions to obtain the HPLC fingerprint spectrum of the allinase inactivated extract of the six-peal red garlics; analyzing the HPLC fingerprint spectrums of ten batches of samples to determine a common characteristic peak and obtaining a standard fingerprint spectrum which can provide a reliable basis for the identification of varieties and production places of the six-peal red garlics and control over the production quality. The establishment method disclosed by the invention has the advantages of convenience in operation, high stability, high specificity, good reproducibility, more characteristic peaks and high analytic efficiency; by using the establishment method disclosed by the invention, the authenticity and production place of the six-peal red garlics can be identified, and the internal quality of the six-peal red garlics can be evaluated comprehensively, accurately and effectively.

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 "Liupethong" garlic allinase inactivated extracts 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....
