Matricaria chamomilla (Asteraceae), commonly known as chamomile can tolerate freezing temperatures and grows in many soil types. This plant is found on all continents and has significant medicinal value. There are more than 120 chemicals detected in chamomile flowers, with the majority found in the essential oil. In this study, M. chamomilla was given the NaCl stress of 0 mM, 1 mM, 100 mM, and 150 mM concentrations This study was the first to assess the efficacy of German chamomile upon exposure to salt stress hence plant particles that had been dried and powdered were analyzed using, phytochemical tests, Fourier Transform Infrared and UV-Vis spectroscopy, thin layer chromatography, fluorescence recovery after photobleaching assay, antibacterial and antioxidant activity. The characterization and results of these activities show amazing results which enhance their antibacterial property with an increased zone of inhibition when the samples of salt stress of the above-given concentrations were compared to the control samples. More graph analysis indicates an effective impact of salt stress on the phytoconstituents of M. chamomilla. Other than that, there was a clear flower induction upon salt stress, as a variety of compounds are regarded as essential to the biological functions of chamomile flowers according to the phytoconstituent screening which can be further used in the cosmetic industry, pharmaceutical industry, and all other fields as well for various application as a nano-drug or bio-drug. Due to this, this plant became essential for plant biotechnology research.
春黄菊（菊科），俗称甘菊，能耐受低温，可在多种土壤类型中生长。这种植物在各大洲都有发现，具有重要的药用价值。在甘菊花中检测到超过 120 种化学物质，其中大部分存在于精油中。在这项研究中，春黄菊受到 0 mM、1 mM、100 mM 和 150 mM 浓度的 NaCl 胁迫。这项研究首次评估了德国甘菊在盐胁迫下的功效，因此对已干燥和粉碎的植物颗粒进行了分析，采用植物化学测试、傅里叶变换红外和紫外可见光谱、薄层色谱、光漂白后荧光恢复试验、抗菌和抗氧化活性。这些活性的特征和结果显示出惊人的效果，当将上述浓度的盐胁迫样品与对照样品进行比较时，其抑制区的增加增强了其抗菌特性。更多的图谱分析表明，盐胁迫对春黄菊的植物成分有明显的影响。除此之外，在盐胁迫下，明显诱导了花的产生，因为根据植物成分筛选，有多种化合物被认为对甘菊花的生物功能至关重要，这些化合物可以进一步用于化妆品行业、制药行业以及其他各个领域，作为纳米药物或生物药物有各种应用。由于这一点，这种植物对植物生物技术研究变得至关重要。
