Abstract

The globe artichoke belongs to the Asteraceae family and has become more and more popular among other vegetables due to its beneficial health-promoting features that are related to bioactive compounds present in leaves. The plant materials have inadequate proportions of valuable bioactive compounds in nature, so researchers are emphasizing on how to enhance their amounts. In vitro techniques with integrated novel practices can be employed to enhance phytochemicals from any plant. The current study aimed to determine and assess valuable bioactive components in 3 artichoke cultivars via callus cultures which were subjected to a treatment of 4 different concentrations (2.5, 5.0, 10.0, and 15.0 mg L-1) of silver nitrate. Results indicated that well-balanced levels of plant growth regulators were necessary for stimulating the callus formation of globe artichoke. The findings of the current study also revealed the importance of cultivar differences regarding callus formation. Experimental results revealed that variation in silver nitrate concentrations had a significant effect on biomass, total phenolic content and total antioxidant activities. The results of the current, study may offer a good strategy by promoting bioactive compounds of globe artichoke leaves for utilizing in large-scale industries, pharmacology, and food supplements.

硝酸银作为激发剂增加洋蓟[Cynara cardunculus vars . scolymus (L.)]生物活性物质的研究愈伤组织培养

洋蓟属于菊科植物，由于其叶片中存在的生物活性化合物具有有益的促进健康的特性，在其他蔬菜中越来越受欢迎。植物材料中有价值的生物活性物质在自然界中所占的比例不足，因此如何提高其含量成为研究的重点。综合新颖实践的体外技术可用于从任何植物中提取植物化学物质。本研究旨在通过4种不同浓度(2.5、5.0、10.0和15.0 mg L-1)硝酸银处理的愈伤组织培养，确定和评估3个洋蓟品种有价值的生物活性成分。结果表明，平衡水平的植物生长调节剂是促进洋蓟愈伤组织形成的必要条件。本研究结果还揭示了愈伤组织形成的品种差异的重要性。实验结果表明，硝酸银浓度的变化对生物量、总酚含量和总抗氧化活性有显著影响。本研究结果为促进洋蓟叶生物活性物质在工业、药理学和食品添加剂等方面的大规模利用提供了良好的策略。
