Abstract

Medicinal plants are rich in secondary metabolites (alkoloids, glycosides, coumarins, flavonides, steroids, etc.) and considered to be more effective and a safer alternative source to manage a variety of diseases related to liver, heart and kidney disordered. This study determines in vitro antioxidant and in vivo toxicological profile including hemolytic, brine shrimp lethality and mutagenicity of aerial parts of Artemisia absinthium. DNA protection assay was performed on pUC19 plasmid vector using H(2)O(2) as oxidative agent. Total phenolic and flavonoid content were determined using colorimetric methods. Toxicity of the plant was evaluated by brine shrimp lethality, hemolytic and mutagenic activity. DNA protection assay of the plant showed concentration dependent protective effect and at concentration 10μL/mL revealed complete protective effect against H(2)O(2) induced DNA damage. Highest phenolic and flavonoid content was found to be 167.3 (mg GAE 100g DW(-1)) and 14 (mg CE 100g DW(-1)) respectively. Results showed that A. absinthium is potent against standard toxicological procedures, that indicates the presence of bioactive components in the plant and possess antioxidant activity that protects DNA against H(2)O(2) induced oxidative damage. Thus the results showed/support that A. absinthium provides significant health benefits.

摘要

药用植物富含次生代谢产物(生物碱、糖苷、香豆素、黄酮类、甾体等),被认为是治疗各种与肝脏、心脏和肾脏疾病相关病症的更有效且更安全的替代来源。本研究测定了苦艾地上部分的体外抗氧化和体内毒理学特征,包括溶血、卤虫致死和致突变性。以过氧化氢作为氧化剂,对pUC19质粒载体进行DNA保护试验。采用比色法测定总酚和黄酮含量。通过卤虫致死、溶血和致突变活性评估该植物的毒性。该植物的DNA保护试验显示出浓度依赖性保护作用,在浓度为10μL/mL时对过氧化氢诱导的DNA损伤显示出完全保护作用。发现最高酚含量和黄酮含量分别为167.3(mg GAE 100g DW⁻¹)和14(mg CE 100g DW⁻¹)。结果表明,苦艾对标准毒理学程序有效,这表明该植物中存在生物活性成分,并具有保护DNA免受过氧化氢诱导的氧化损伤的抗氧化活性。因此,结果表明/支持苦艾具有显著的健康益处。
