Abstract

In the present study, we addressed the imperative for potent anticancer agents through , a medicinal plant abundant in the robust antihepatotoxic and antitumor compound wedelolactone. Hindrances in conventional propagation methods due to cross-pollination and habitat degradation prompted us to pioneer rapid multiplication using plant tissue culture. Optimal outcomes were attained employing Murashige and Skoog (MS) medium supplemented with Indole-3-butyric acid (IBA) (0.5 mg/L) and Kinetin (KN) (5.0 mg/L), yielding 97.67% shoot regeneration and 81.67% rooting from nodal explants. Transplanted plantlets exhibited a 92% survival rate. We established a wedelolactone extraction protocol using toluene:ethyl acetate:formic acid (5:4:1) for High-performance thin-layer chromatography (HPTLC) analysis, trailblazing wedelolactone quantification and 2C DNA analysis in via flow cytometry. Experiments under heavy metal stress with CuSO unveiled physiological responses, with peak wedelolactone content [193.90 μg/g dry weight (dw)] at 75 μM CuSO, surpassing levels (89.95 μg/g dw) by 116%. By pioneering successful rapid multiplication and enhanced wedelolactone content, we bridge a critical gap in the conservation and production of this medicinal plant. Our findings not only offer a sustainable means of propagation but also present a viable strategy for elevating the yield of potent bioactive molecules like wedelolactone, holding immense promise for the development of novel therapeutic interventions and addressing the pressing healthcare challenges of our time.

摘要

在本研究中,我们通过一种富含强效抗肝毒性和抗肿瘤化合物蟛蜞菊内酯的药用植物,来探讨对高效抗癌药物的需求。由于异花授粉和栖息地退化,传统繁殖方法存在障碍,这促使我们率先采用植物组织培养进行快速繁殖。使用添加了吲哚 - 3 - 丁酸(IBA)(0.5 mg/L)和激动素(KN)(5.0 mg/L)的Murashige和Skoog(MS)培养基取得了最佳结果,从节段外植体产生了97.67%的芽再生和81.67%的生根。移栽的小植株存活率为92%。我们建立了一种用于高效薄层色谱(HPTLC)分析的甲苯:乙酸乙酯:甲酸(5:4:1)的蟛蜞菊内酯提取方案,开创了通过流式细胞术对蟛蜞菊内酯进行定量和2C DNA分析的先河。在硫酸铜重金属胁迫下的实验揭示了生理反应,在75 μM硫酸铜时蟛蜞菊内酯含量达到峰值[193.90 μg/g干重(dw)],比对照水平(89.95 μg/g dw)高出116%。通过率先成功实现快速繁殖并提高蟛蜞菊内酯含量,我们填补了这种药用植物保护和生产方面的关键空白。我们的研究结果不仅提供了一种可持续的繁殖方法,还提出了一种可行的策略来提高像蟛蜞菊内酯这样的强效生物活性分子的产量,为新型治疗干预措施的开发以及应对我们这个时代紧迫的医疗保健挑战带来了巨大希望。
