Abstract

has been studied for its vast medical and industrial potential. Phytochemical investigations reveal that the genus is a rich source of lignans, flavonoids, phenolics, terpenoids, and other metabolites. However, the phytochemical profile elucidation of this species still needs further research. The use of eliciting compounds such as salicylic acid and methyl jasmonate has managed to increase the production of secondary metabolites in plant cell cultures. Hairy roots of were produced in 250 mL flasks with a 16 h light/8 h darkness photoperiod under diffused light with a culture time of four weeks. The elicitors salicylic acid and methyl jasmonate were tested in 50 μM and 200 μM concentrations. Non-targeted analysis was done for the different treatments using HR-MS. Identified metabolites were grouped in phenylpropanoids, phenols, and mucic acids, and statistical analysis of relative concentrations was achieved. A significant change in phenols' relative concentrations appeared in the elicitations with salicylic acid. Because of the elicitation treatment, specific compounds increased their concentrations, some of which have known pharmacological effects and are used in treating chronic diseases. The best elicitation treatment was salicylic acid 50 μM as it increased by more than 100% the general content of phenols and phenylpropanoid derivates and triplicates the concentration of mucic acid derivates in treated hairy root extracts. The application of non-targeted analysis showed interesting changes in phytochemical concentration due to elicitation in hairy roots.

摘要

已经研究了其广泛的医学和工业潜力。植物化学研究表明,该属是木脂素、类黄酮、酚类、萜类和其他代谢物的丰富来源。然而,这种植物的植物化学特征的阐明仍需要进一步研究。使用水杨酸和茉莉酸甲酯等诱导化合物已经成功地增加了植物细胞培养物中次生代谢产物的产量。在光照 16 小时/黑暗 8 小时的光周期下,在漫射光下,用 250 毫升培养瓶培养了四周的 发根。测试了水杨酸和茉莉酸甲酯 50 μM 和 200 μM 浓度的诱导作用。使用 HR-MS 对不同处理进行非靶向分析。将鉴定出的代谢物分为苯丙素类、酚类和粘酸类,并对相对浓度进行了统计分析。在水杨酸的诱导作用下,酚类的相对浓度出现了显著变化。由于诱导处理,一些具有已知药理作用并用于治疗慢性疾病的特定化合物增加了它们的浓度。最佳诱导处理是 50 μM 水杨酸,因为它使总酚类和苯丙素衍生物的含量增加了 100%以上,并使处理后的发根提取物中粘酸衍生物的浓度增加了两倍。非靶向分析的应用显示,由于 发根的诱导作用,植物化学浓度发生了有趣的变化。
