摘要:

为研究花椒麻素的抗氧化活性,采用体外抗氧化实验,评价不同剂量花椒麻素的总抗氧化能力、还原力以及对羟自由基(.OH)和1,1-二苯基-2-三硝基苯肼(1,1-diphenyl-2-picrylhydrazyl,DPPH)自由基的清除作用,并以人肝癌细胞HepG2为模型,探讨其在细胞水平的抗氧化能力。结果表明:花椒麻素具有一定的还原力和总抗氧化能力,且呈现良好的剂量-效应关系;但对DPPH自由基、.OH的清除作用较弱。花椒麻素在较低质量浓度(0~50 μg/mL)条件下可使HepG2细胞内超氧化物歧化酶(superoxide dismutase,SOD)活性降低,丙二醛(malondialdehyde,MDA)含量增加,但当花椒麻素质量浓度达到100 μg/mL时,细胞SOD活性显著增加,MDA含量则显著降低(P<0.05)。因此,花椒麻素是一类潜在的抗氧化物质,可用于此类功能食品的开发。

Abstract:

The antioxidant activity in vitro of sanshool from Sichuan peppers (Zanthoxylum bungeanum) was assessed by
total antioxidant capacity, reducing power and scavenging capacities against hydroxyl and 1,1-diphenyl-2-picrylhydrazyl
(DPPH) free radicals as well as its cellular antioxidant activity on human liver HepG2 cells. The results indicated that
sanshool had a certain reducing power and total antioxidant capacity in a dose-effect manner, but the scavenging activity on
DPPH and hydroxyl radicals was a little weak. The cellular antioxidant activity on human liver HepG2 cells showed that at
lower concentrations (0–50 μg/mL) of sanshool, superoxide dismutase (SOD) activity was decreased and malondialdehyde
(MDA) content was increased. At a concentration up to 100 μg/mL, SOD activity was increased significantly and MDA
content was reduced significantly (P < 0.05). Therefore, sanshool is can be considered as a potential antioxidant ingredient
for functional foods.

Key words: sanshool, antioxidant activity, HepG2 cells
