Quality Evaluation of Wild Germplasm of Chinese Prickly Ash (Zanthoxylum bungeanum Maxim) from Qinling Mountains at Different Elevations Based on HPLC‐Fingerprint**

Abstract

Wild Chinese prickly ash resources provide a valuable genetic resource for Zanthoxylum bungeanum Maxim improvement and breeding. The Qinling Mountains was an abundant source for wild Chinese prickly ash. In this study, the phenolic and flavonoid compounds of wild germplasm resources from different altitudes and six cultivated varieties were analyzed by high performance liquid chromatography (HPLC). The chromatograms of them were essentially consistent, although their chemical composition contents were greatly different. The thirty samples were divided into three categories through the hierarchical clustering analysis. Catechin, hyperoside and quercitrin were considered to be key compounds for the quality evaluation, and by contrast, the wild samples with an altitude of 2300 � 50 m (Group IV) had the highest content of key compounds, and presented stronger antioxidant activity and antibacterial ability, indicating that these wild samples could be identified as the excellent breeding resources. This is the first time to evaluate the quality of wild Chinese prickly ash at different altitudes in Qinling Mountains. These excellent wild germplasm resources provided substantial potential accessions for use directly in Chinese prickly ash breeding programs.

Evaluation of climate factors affecting the quality of red huajiao (Zanthoxylum bungeanum maxim.) based on UPLC-MS/MS and MaxEnt model

“…Huajiao ( Zanthoxylum bungeanum Maxim.) belongs to the Zanthoxylum genus in Rutaceae family, and includes approximately 250 species, of which red huajiao is one of most commercially popular varieties ( Zheng et al, 2020 , Zheng et al, 2022 ). Red huajiao has been widely cultivated in China with strong ecological adaptation, of which Sichuan, Shaanxi and Gansu provinces are the main planting areas ( Zhuo et al, 2020 ).…”

Evaluating the Impacts of Climate Factors and Flavonoids Content on Chinese Prickly Ash Peel Color Based on HPLC-MS and Structural Equation Model

“…Zanthoxylum bungeanum Maxim., known as Chinese prickly ash, is widely distributed in China and was the most important, traditional condiment and medicinal plant in China for hundreds of years and has strong ecological adaptation [ 1 , 2 , 3 ]. Due to the influence of other species, geographical conditions, climate factors and chemical composition, the color of Chinese prickly ash peel produced in different regions is different [ 4 ]. The main chemical components involved in Chinese prickly ash peel color are flavonoids, volatile oil, alkaloids, amides, and so on, of which flavonoids are natural pigments with good stability.…”
