Abstract:

The project studied the preservation mode of Linxia Zanthoxylum bungeanum Maxim with the least loss of numb-taste components under different conditions. The native Zanthoxylum bungeanum Maxim in Linxia of Gansu Province was used as the experimental material. The main components and the change of the concentration of numb-taste substance of Zanthoxylum bungeanum Maxim at different storage temperatures, of different particle sizes, with different storage materials and under different storage methods were analyzed by high performance liquid chromatography. The results showed that the main components were: hydroxy-α-sanshool of 38.19 mg/g and hydroxy-β-sanshool of 2.45 mg/g, and schinifoline was not detected. The numb-taste components of Linxia Zanthoxylum bungeanum Maxim were mainly the sum of the above two substances. The results also showed that whole prickly ash was easier to be preserved than broken prickly ash. Temperature was negatively correlated with numb-taste substance content of Zanthoxylum bungeanum Maxim. Under the same temperature, the preservation effect on Zanthoxylum bungeanum Maxim numb-taste components was as follows: vacuum aluminum foil bag >non-vacuum foil bag >vacuum glass bottle >non-vacuum plastic bottle >non-vacuum conventional plastic bag.

Key words: Zanthoxylum bungeanum Maxim, storage, high performance liquid chromatography, temperature, numb-taste components
