<p>This study aimed to evaluate the effects of elevated ultraviolet-B (eUV-B) radiation and chromium (Cr), alone and in combination, on yield attributes, metabolic profile, reactive oxygen species (ROS) scavenging activity, bioaccumulation, and translocation&#xa0;of Cr in the medicinal plant <i>Psoralea corylifolia</i> L.&#xa0;(bakuchi). The experiment was conducted under natural field conditions using four treatments: (i) control, (ii) Cr treatment (30&#xa0;mg&#xa0;kg<sup>−1</sup>), (iii) eUV-B treatment (ambient + 7.2&#xa0;kJm<sup>−2</sup>d<sup>−1</sup>), and (iv) Cr + eUV-B treatment (Cr 30&#xa0;mg&#xa0;kg<sup>−1</sup> and ambient + 7.2&#xa0;kJm<sup>−2</sup>d<sup>−1</sup> UV-B). The results of the study indicated that the bioaccumulation and translocation factor for Cr ranged below one under all treatments. The number of seeds showed a considerable reduction under the treatments; nevertheless, seed length, diameter, and test weight demonstrated no significant variation as compared to the control across all treatments. Gas chromatography mass spectrometry analysis of the extract of <i>P. corylifolia</i> seeds revealed that key metabolites like bakuchiol, isopsoralen, and psoralen, which are known for their anti-vitiligo, anti-inflammatory, and anticancer properties, were enhanced in all treatments. The highest increases in psoralen and isopsoralen were observed under combined treatment, while bakuchiol showed the maximum increase under individual eUV-B treatment.

Our findings highlight that <i>P. corylifolia</i> can thrive well in environments with high levels of UV-B and Cr, and can be exploited for the valuable secondary metabolites for pharmaceutical purposes.</p>

摘要

This study aimed to evaluate the effects of elevated ultraviolet-B (eUV-B) radiation and chromium (Cr), alone and in combination, on yield attributes, metabolic profile, reactive oxygen species (ROS) scavenging activity, bioaccumulation, and translocation of Cr in the medicinal plant Psoralea corylifolia L. (bakuchi). The experiment was conducted under natural field conditions using four treatments: (i) control, (ii) Cr treatment (30 mg kg−1), (iii) eUV-B treatment (ambient + 7.2 kJm−2d−1), and (iv) Cr + eUV-B treatment (Cr 30 mg kg−1 and ambient + 7.2 kJm−2d−1 UV-B). The results of the study indicated that the bioaccumulation and translocation factor for Cr ranged below one under all treatments. The number of seeds showed a considerable reduction under the treatments; nevertheless, seed length, diameter, and test weight demonstrated no significant variation as compared to the control across all treatments. Gas chromatography mass spectrometry analysis of the extract of P. corylifolia seeds revealed that key metabolites like bakuchiol, isopsoralen, and psoralen, which are known for their anti-vitiligo, anti-inflammatory, and anticancer properties, were enhanced in all treatments. The highest increases in psoralen and isopsoralen were observed under combined treatment, while bakuchiol showed the maximum increase under individual eUV-B treatment. Further, the ROS scavenging activity of the methanolic extract of seeds revealed a significant increase under individual eUV-B and combined treatments of eUV-B and Cr. Our findings highlight that P. corylifolia can thrive well in environments with high levels of UV-B and Cr, and can be exploited for the valuable secondary metabolites for pharmaceutical purposes.
