Somatic embryogenesis and triterpenoid saponin production in Aralia elata (Miq.) Seem

•A micropropagation protocol for Aralia elata (Miq.) Seem through indirect somatic embryogenesis is described.•Stems apices was the best explants for callus induction in A. elata.•2,4-D was the most effective auxins for callus induction in A. elata species.•IBA not only induced somatic embryogenesis but also induced adventitious root formation.•Somatic embryogenesis significantly influenced by light intensity.•Light intensity positively regulate total saponin accumulation of A. elata.
