Ginger ( Roscoe) can scavenge free radicals, which cause oxidative damage and inflamm-ageing. This study aimed to evaluate the antioxidant and anti-inflammatory effects of soil ginger's sub-critical water extracts (SWE) on different ages of Sprague Dawley (SD) rats. The antioxidant properties and yield of SWE of soil- and soilless-grown ginger (soil ginger and soilless ginger will be used throughout the passage) were compared and evaluated. Three (young), nine (adult), and twenty-one (old) months old SD rats were subjected to oral gavage treatments with either distilled water or the SWE of soil ginger at a concentration of 200 mg/kg body weight (BW) for three months. Soil ginger was found to yield 46% more extract than soilless ginger. While [6]-shogaol was more prevalent in soilless ginger, and [6]-gingerol concentration was higher in soil ginger ( < 0.05). Interestingly, soil ginger exhibited higher antioxidant activities than soilless ginger by using 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assay. With ginger treatment, a reduced levels of tumour necrosis factor-α (TNF-α) and C-reactive protein (CRP) but not interleukin-6 (IL-6) were observed in young rats. In all ages of SD rats, ginger treatment boosted catalase activity while lowering malondialdehyde (MDA). Reduction of urine 15-isoprostane F in young rats, creatine kinase-MM (CK-MM) in adult and old rats and lipid peroxidation (LPO) in young and adult rats were also observed. The findings confirmed that the SWE of both soil and soilless grown ginger possessed antioxidant activities. Soil ginger produced a higher yield of extracts with a more prominent antioxidant activity. The SWE of soil ginger treatment on the different ages of SD rats ameliorates oxidative stress and inflammation responses. This could serve as the basis for developing a nutraceutical that can be used as a therapeutic intervention for ageing-related diseases.
姜(Roscoe)能够清除自由基,而自由基会导致氧化损伤和炎症衰老。本研究旨在评估土培生姜亚临界水提取物(SWE)对不同年龄的斯普拉格-道利(SD)大鼠的抗氧化和抗炎作用。比较并评估了土培和无土栽培生姜(在整篇文章中将使用土培生姜和无土栽培生姜)的SWE的抗氧化特性和产量。将三个月大(幼年)、九个月大(成年)和二十一个月大(老年)的SD大鼠分为两组,分别用蒸馏水或浓度为200毫克/千克体重(BW)的土培生姜SWE进行为期三个月的灌胃处理。结果发现,土培生姜的提取物产量比无土栽培生姜高46%。虽然[6]-姜烯酚在无土栽培生姜中更为普遍,但[6]-姜酚在土培生姜中的浓度更高(P<0.05)。有趣的是,通过2,2-二苯基-1-(2,4,6-三硝基苯基)肼(DPPH)和铁还原抗氧化能力(FRAP)测定,土培生姜比无土栽培生姜表现出更高的抗氧化活性。经生姜处理后,幼年大鼠的肿瘤坏死因子-α(TNF-α)和C反应蛋白(CRP)水平降低,但白细胞介素-6(IL-6)水平未降低。在所有年龄的SD大鼠中,生姜处理提高了过氧化氢酶活性,同时降低了丙二醛(MDA)水平。在幼年大鼠中还观察到尿15-异前列腺素F降低,在成年和老年大鼠中观察到肌酸激酶-MM(CK-MM)降低,在幼年和成年大鼠中观察到脂质过氧化(LPO)降低。研究结果证实,土培和无土栽培生姜的SWE均具有抗氧化活性。土培生姜提取物产量更高,抗氧化活性更显著。土培生姜SWE对不同年龄的SD大鼠进行处理可改善氧化应激和炎症反应。这可为开发一种可用于治疗与衰老相关疾病的营养保健品奠定基础。
