“…Amino acids and their derivatives serve to activate plant defense mechanisms during plant growth and the development and stress response [49]. Some investigations have suggested that the increase in amino acid levels caused by stress is related to increased nitrogen storage and serves as a precursor for the production of secondary metabolites in plants [50][51][52].…”

Asarum (Asarum sieboldii Miq. f. seoulense (Nakai) C. Y. Cheng et C. S. Yang) is a medicinal plant that contains asarinin and sesamin, which possess extensive medicinal value. The adaptation and distribution of Asarum’s plant growth are significantly affected by altitude. Although most studies on Asarum have concentrated on its pharmacological activities, little is known about its growth and metabolites with respect to altitude. In this study, the physiology, ionomics, and metabolomics were investigated and conducted on the leaves and roots of Asarum along an altitude gradient, and the content of its medicinal components was determined. The results showed that soil pH and temperature both decreased along the altitude, which restricts the growth of Asarum. The accumulation of TOC, Cu, Mg, and other mineral elements enhanced the photosynthetic capacity and leaf plasticity of Asarum in high-altitude areas. A metabolomics analysis revealed that, at high altitude, nitrogen metabolism in leaves was enhanced, while carbon metabolism in roots was enhanced. Furthermore, the metabolic pathways of some phenolic substances, including syringic acid, vanillic acid, and ferulic acid, were altered to enhance the metabolism of organic acids. The study uncovered the growth and metabolic responses of Asarum to varying altitudes, providing a theoretical foundation for the utilization and cultivation of Asarum.

“…Iridoid gylcosides are considered responsible for hepatoprotective properties of the plant. Other constituents present in this plant are cucurbitacins (B, D, and R) [ 20 ], minecoside, picein, pikuroside, flavonoid apocyanin, vanillic acid, ferullic acid, D-mannitol [ 19 , 21 ], a ketone kutkiol, kutkisterol, and phenolic glycosides such as apocyanin (4′-hydroxy-3′-methoxy acetophenone), androsin, picein [ 22 , 23 ], triterpenoids (in seeds) [ 17 ], lignan, coumarin, isoflavans, porphyrins, terpene lactone [ 24 ], and phenylethanoid glycosides (kurroaoside) [ 25 ]. Cucurbitacins are renowned for their antitumor and cytotoxic attributes.…”

Picrorhiza kurrooa Royle ex Benth. is one of the well-established herbal plants with an exceptional therapeutic potential. It belongs to the Scrophulariaceae family and is commonly called as kutki. The drug obtained from the plant is a bitter tonic due to the presence of kutkin in it. Over 61 secondary metabolites from the plants have been identified, including iridoid glycosides, flavonoids, cucurbitacins, and phenolic chemicals. However, picrosides are the major phytochemicals in this species that are responsible for its well-known hepatoprotective properties. The present study was conducted to compare Picrorhiza kurrooa (dried rhizomes) obtained from local traders from the markets of three different districts of Uttarakhand, i.e., the Dewal block of Chamoli, Ukhimath block of Rudraprayag, and Dharchula block of Pithoragarh. Biochemical analysis was conducted on the powder of dried rhizomes for alkaloids, phenolics, tannins, flavonoids, and antioxidant activity. Based on analysis, it was found that the total phenolic content, total flavonoid content, total alkaloid content, and radical scavenging activity of P. kurrooa rhizomes purchased from Darma valley, Pithoragarh district of Uttarakhand, were the highest, followed by rhizomes collected from the Dewal block of Chamoli district and the least were found in rhizomes obtained from the Ukhimath block of Rudraprayag district of Uttarakhand. The maximum tannin content was found in Picrorhiza kurrooa rhizomes obtained from the Dewal block of Chamoli, while total reducing power was observed the highest in rhizomes from the Ukhimath block of Rudraprayag. The results provided evidence that P. kurrooa obtained from Darma valley, Pithoragarh, are the potential source of phenolics, flavonoids, and tannins and have the highest DPPH-scavenging activity and therefore could be served as the basis for future drugs and food materials.
