Messerschmidia sibirica is a halophyte that grows in high-salinity areas of coastal sand dunes and sandy shores. This
study was conducted to investigate the constituents, antioxidant potency, and physiological activities of M. sibirica.
Mineral analyses revealed that potassium, calcium, sodium, and magnesium were the most prevalent minerals in M.
sibirica leaves and stems. We used 70% ethanol, 80% methanol, and distilled water as solvents to prepare extracts
from M. sibirica tissues, with extraction yields of between approximately 19% and 27% being obtained. Among the
six types of extract, the leaf ethanol extract (LEE) was characterized by the highest total polyphenol and flavonoid
contents, and the antioxidant activities of the LEE were also the highest among the different solvent extracts. In addition,
the leaf water extract was shown to have the highest tyrosinase and α-glucosidase inhibitory activities, whereas
the leaf methanol extract was found to have the highest elastase inhibitory activity. Notably, all leaf extracts were
established to have more than 75% β-secretase (BACE1) inhibitory activity at a final concentration of 0.5 mg/mL.
These results indicate that leaf extracts of M. sibirica may have beneficial antioxidant properties, and could thus have
potential application as functional supplements in food and pharmaceutical products.
