Abstract

C.J. Tseng tea and insect tea, as traditional Chinese teas, are favored for their original craftsmanship, unique flavor, and biological functionality. In this study, ultra high-performance liquid chromatography-triple quadrupole mass spectrometry (UHPLC-QqQ-MS) was used to analyze the bioactive components of the extracts of and , and D-galactose-induced aging mice were used to compare the anti-aging effects of and extracts. The results were remarkable, UHPLC-QqQ-MS analysis showed that ITP contains 29 ingredients, while IKDCP contains 26 ingredients. However, due to the large differences in the content of the main chemical components in IKDCP and ITP, the effects are equally different. At the same time, the research results suggesting that the anti-aging effects of IKDCP and ITP (500 mg/kg) include the regulation of viscera indices of major organs; improvement in liver, skin, and spleen tissue morphology; decreased production of inflammatory cytokines; up regulation of , and and down regulation of and levels in serum and liver tissue; reductions in the concentration of pro-inflammatory factors, and increases in the concentration of anti-inflammatory factor. and western blot assay also showed that IKDCP and ITP affect anti-aging by regulating the gene and protein expression of , and . The overall results indicate that ITP is more effective in treating oxidative damage in aging mice induced by D-galactose. Thus, ITP appears to be an effective functional drink owing to its rich nutritional components and anti-aging activities.

摘要

曾氏茶和虫茶作为中国传统茶叶,因其原始工艺、独特风味和生物功能而备受青睐。在本研究中,采用超高效液相色谱 - 三重四极杆质谱联用仪(UHPLC - QqQ - MS)分析了曾氏茶和虫茶提取物的生物活性成分,并使用D - 半乳糖诱导的衰老小鼠比较了曾氏茶和虫茶提取物的抗衰老作用。结果显著,UHPLC - QqQ - MS分析表明,曾氏茶含有29种成分,而虫茶含有26种成分。然而,由于虫茶和曾氏茶中主要化学成分含量差异较大,其效果也同样不同。同时,研究结果表明,虫茶和曾氏茶(500 mg/kg)的抗衰老作用包括调节主要器官的内脏指数;改善肝脏、皮肤和脾脏组织形态;减少炎症细胞因子的产生;上调血清和肝脏组织中SOD、CAT和GSH - Px水平以及下调MDA和NO水平;降低促炎因子浓度,增加抗炎因子浓度。免疫组化和蛋白质印迹分析还表明,虫茶和曾氏茶通过调节SOD、CAT和GSH - Px的基因和蛋白表达来影响抗衰老作用。总体结果表明,曾氏茶在治疗D - 半乳糖诱导的衰老小鼠氧化损伤方面更有效。因此,曾氏茶因其丰富的营养成分和抗衰老活性,似乎是一种有效的功能性饮品。
