“…Concentrations of TSs in A. elata leaves were determined by adapted methods by Kuang et al (1996) (araloside A and araloside B), Xia et al (2019), andSun et al (2017a) (araloside V and araloside VI). A total of 10 mg freeze-dried samples were ground and dissolved to 2 mL of 70% methanol (v/v).…”

“…Leaves are an alternative organ instead of buds that produces dry mass with abundant TSs. Currently, TS compounds that were extracted from A. elata included aralosides in types-A, -B, -V, and -VI, ginsenoside R0 (i.e., chikusetsusaponin V), and chikusetsusaponin Iva (Kuang et al, 1996;Sun et al, 2017a;Xia et al, 2019;Yang et al, 2018). Methodology to determine these TS compounds have been well established (Han et al, 2021;Sun et al, 2017a;Wang et al, 2014).…”

Combined light spectra and nitrogen (N) availability may modify contents of triterpenoid saponins (TSs) in leaves of Aralia elata (Miq.) Seem. In this study, A. elata seedlings were raised under light-emitting diode spectra in red- (26.6% red, 59.9% green, and 13.5% blue) and green-colours (12.6% red, 84.6% green, and 2.9% blue) both at a photosynthetic photon flux density of about 77.4 µmol m-2 s-1. N availability was employed at low and high rates of 30 and 90 mg kg-1, respectively. Aralosides-A and -VI did not show any responses to either light or N treatments (ranges of 1.98‒3.75 mg g-1 and 0.21‒1.41 mg g-1, respectively). Compared to the green light, the red light resulted in greater growth but lower foliar N assimilation and aralosides-B (~0.7 mg g-1) and -V concentrations (~16 mg kg-1). The high N availability resulted in greater growth, biomass, foliar chlorophyl and protein concentrations but lower N assimilation and TS concentrations. We conclude that araloside B can be taken as an objective TS harvested in A. elata food-used leaves as a bioactive compound that can be adjusted by light and N manipulations.
