Abstract

The invention discloses an establishment method of inducing callus cultured Allium sativum L. enzymatic hydrolysate HPLC fingerprints. The establishment method of the inducing callus cultured Allium sativum L. enzymatic hydrolysate HPLC fingerprints specifically comprises the steps of preparing inducing callus cultured Allium sativum L. bulbs into solution for test products through steps such as solid-phase extraction, and performing high-performance chromatographic analysis and detection under certain conditions to obtain HPLC fingerprints of inducing callus cultured Allium sativum L. enzymatic hydrolysate. By analyzing the HPLC fingerprints of 10 batches of samples, characteristic common peaks are determined and standard fingerprints are obtained. The standard fingerprints can provide a reliable basis for variety identification and production quality control of inducing callus cultured Allium sativum L. The establishment method of the inducing callus cultured Allium sativum L. enzymatic hydrolysate HPLC fingerprints has the advantages that the operation is convenient, the stability is high, the specificity is strong, the repeatability is good, the characteristic peaks are more, the analysis efficiency is high, the truth identification of the inducing callus cultured Allium sativum L. can be realized by adopting the invention, and the interior product quality can be comprehensively, accurately and effectively evaluated.

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 a method for constructing plant fingerprints for induced callus culture, in particular to a method for constructing high-performance liquid chromatography (HPLC) fingerprints for induced callus cultured 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 vegetable and condiment in people's life, garli...
