Neither the chemical profile and bioactivity of the fruits of Eleutherococcus species cultivated in Poland nor the influence of long-term domestic storage of the fruits are known. No changes in the phenols and flavonoids content in the freshly dried and 1-year storage fruits of Eleutherococcus senticosus and Eleutherococcus henryi were found. The 1-year storage fruits of both species exhibited a very high concentration of Mn, Zn and Cu (mg/kg) compared with the fresh-dried fruits. Spathulenol, β-longipinene and iso-longifolol were predominant essential oil compounds. It was observed that a high capacity of the freshly dried E. senticosus fruits were able to scavenge DPPH* and inhibit Hyal (EC50 0.1 mg/mL; IC50 0.58 mg/mL). Due to their health and pharmacological benefits, a better understanding of the impact of the climate change is important to increase the pharmacological utility of the extracts.
