Changes in qualities of dried Zanthoxylum armatum DC. at different storage methods

Degradation and transformation mechanisms of numbing substances: Hydroxyl-α-sanshool & hydroxyl-β-sanshool from Zanthoxylum bungeanum exposed to acid environment

“…3 (d)): One part is from a small amount of hydroxyl-α-sanshool that has not been completely transformed in the solution, part of hydroxyl-α-sanshool is transformed from hydroxyl-β-sanshool. The results showed that the two kinds of sanshools could be transformed into each other under certain conditions, which is consistent with the results of Cheng et al (2021) .…”

“…The alkylamides in Z. bungeanum are easily oxidized due to the presence of three conjugated double bonds ( Bryant & Mezine, 1999 ). Cheng et al (2021) investigated the impact of different storage conditions on the qualities of dried Z. armatum , including color, numbness, and aroma, for seven months to identify a suitable storage method. The result showed that the optimal way to preserve dried Z. armatum was non-light packaging at −18 °C, and room temperature and light can obviously reduce the content of numbing substances.…”

Effect of Phenol and Alkylamide Interaction on α-Glucosidase Inhibition and Cellular Antioxidant Activity during In Vitro Digestion: Using Szechuan Pepper (Zanthoxylum genus) as a Model

“…Eight alkylamide metabolites (M16–M23) were generated during digestion (Figure and Table ). α-SOH, containing a cis double bond, underwent various reactions, including oxidation, isomerization, and polymerization . M7 (α-SOH) was isomerized into M6 (ε-SOH) during in vitro digestion.…”

Comprehensive study on nutritional, flavour and metabolite characteristics of green prickly ash (Zanthoxylum schinifolium) at different picking stages

“…Hydroxyl‐γ‐sanshool and hydroxyl‐α‐sanshool contents reached maximum of 1.40 and 115.89 mg g −1 at P85 and P100, respectively, while both hydroxyl‐β‐sanshool and hydroxyl‐ε‐sanshool reached maximum values of 2.74 and 5.06 mg g −1 at P115. Furthermore, all sanshool contents decreased significantly at P130, which might be attributed to the accelerated degradation of sanshool caused by high temperature and strong ultraviolet radiation in summer (Cheng et al ., 2021). Subsequently, all sanshool contents increased slightly at P145, which was closely related to the sharp decline in moisture content at P145.…”
