Artemisia absinthium L. is a highly medicinal plant with a broad range of biomedical applications. A. absinthium callus cultures were established in response to bio-fabricated single NPs (Ag and Cu) or a combination of both NPs (Ag and Cu) in different ratios (1:2, 2:1, 1:3, and 3:1) along with thidiazuron (TDZ) (4 mg/L) to elicit the biomass accumulation, production of non-enzymatic compounds, antioxidative enzymes, and antioxidant activity. Silver and copper nanoparticles (Ag and Cu NPs) were synthesized using the leaves of Moringa oleifera as reducing and capping agent and further characterized through UV-Visible spectroscopy and SEM. The 30 µg/L suspension of Ag and Cu NPs (1:2, 2:1) and 4 mg/L TDZ showed 100% biomass accumulation as compared to control (86%). TDZ in combination with Ag NPs enhanced biomass in the log phases of growth kinetics. The Cu NPs alone enhanced the superoxide dismutase activity (0.56 nM/min/mg FW) and peroxidase activity (0.31 nM/min/mg FW) in callus cultures. However, the combination of Ag and Cu NPs with TDZ induced significant total phenolic (7.31 µg/g DW) and flavonoid contents (9.27 µg/g DW). Furthermore, the antioxidant activity was highest (86%) in the Ag and Cu NPs (3:1) augmented media. The present study provides the first evidence of bio-fabricated single NPs (Ag and Cu) or a combination of both NPs (Ag and Cu) in different ratios (1:2, 2:1, 1:3, and 3:1) along with TDZ (4 mg/L) on the development of callus culture, production of endogenous enzymes, non-enzymatic components, and further antioxidant activity in callus cultures of A. absinthium .

绿色合成的银和铜纳米颗粒诱导了苦艾蒿愈伤组织培养物中生物量参数,次生代谢产物的产生和抗氧化活性的变化。

艾蒿(Asemisia absinthium L.)是一种高度药用植物,具有广泛的生物医学应用。建立了苦艾愈伤组织培养物,以响应以不同比例(1:2、2:1、1、3和3:3)制作的单个NP(Ag和Cu)或两种NP(Ag和Cu)的组合。 1)与噻唑隆(TDZ)(4 mg / L)一起引起生物量的积累,产生非酶化合物,抗氧化酶和抗氧化活性。以辣木的叶子为还原剂和加帽剂,合成了银和铜的纳米粒子(Ag和Cu NPs),并通过紫外-可见光谱和SEM对其进行了表征。Ag和Cu NPs(1:2,2:1)和4 mg / L TDZ的30 µg / L悬浮液与对照(86%)相比,显示出100%的生物量积累。TDZ与Ag NPs结合在生长动力学的对数期提高了生物量。单独的铜纳米颗粒可提高愈伤组织培养物中的超氧化物歧化酶活性(0.56 nM / min / mg FW)和过氧化物酶活性(0.31 nM / min / mg FW)。但是,Ag和Cu NPs与TDZ的组合可诱导显着的总酚类(7.31 µg / g DW)和类黄酮含量(9.27 µg / g DW)。此外,在Ag和Cu NPs(3:1)增强培养基中,抗氧化剂活性最高(86%)。本研究提供了以不同比例(1:2、2:1、1:3和3:1)生物制造的单个NP(Ag和Cu)或两种NP(Ag和Cu)的组合的第一个证据。与TDZ(4 mg / L)一起用于苦艾的愈伤组织培养中愈伤组织培养的发展,内源酶,非酶成分的产生以及进一步的抗氧化活性。在愈伤组织培养物中为31 nM / min / mg FW)。但是,Ag和Cu NPs与TDZ的组合可诱导显着的总酚类(7.31 µg / g DW)和类黄酮含量(9.27 µg / g DW)。此外,在Ag和Cu NPs(3:1)增强培养基中,抗氧化剂活性最高(86%)。本研究提供了以不同比例(1:2、2:1、1:3和3:1)生物制造的单个NP(Ag和Cu)或两种NP(Ag和Cu)的组合的第一个证据。与TDZ(4 mg / L)一起用于苦艾的愈伤组织培养中愈伤组织培养的发展,内源酶,非酶成分的产生以及进一步的抗氧化活性。在愈伤组织培养物中为31 nM / min / mg FW)。但是,Ag和Cu NPs与TDZ的组合可诱导显着的总酚类(7.31 µg / g DW)和类黄酮含量(9.27 µg / g DW)。此外,在Ag和Cu NPs(3:1)增强培养基中,抗氧化剂活性最高(86%)。本研究提供了以不同比例(1:2、2:1、1:3和3:1)生物制造的单个NP(Ag和Cu)或两种NP(Ag和Cu)的组合的第一个证据。与TDZ(4 mg / L)一起用于苦艾的愈伤组织培养中愈伤组织培养的发展,内源酶,非酶成分的产生以及进一步的抗氧化活性。在Ag和Cu NPs(3:1)增强培养基中,抗氧化活性最高(86%)。本研究提供了以不同比例(1:2、2:1、1:3和3:1)生物制造的单个NP(Ag和Cu)或两种NP(Ag和Cu)的组合的第一个证据。与TDZ(4 mg / L)一起用于苦艾的愈伤组织培养中愈伤组织培养的发展,内源酶,非酶成分的产生以及进一步的抗氧化活性。在Ag和Cu NPs(3:1)增强培养基中,抗氧化活性最高(86%)。本研究提供了以不同比例(1:2、2:1、1:3和3:1)生物制造的单个NP(Ag和Cu)或两种NP(Ag和Cu)的组合的第一个证据。与TDZ(4 mg / L)一起用于苦艾的愈伤组织培养中愈伤组织培养的发展,内源酶,非酶成分的产生以及进一步的抗氧化活性。
