Comparative studies on polyphenolic composition, antioxidant and antimicrobial activities of Schisandra chinensis 

extract leaves and fruits.The aim of this paper was to evaluate the antioxidant and antimicrobial activities and 

the polyphenolic content of Schisandra chinensis extract(Turcz.) Baill. leaves and fruits. 


The leaves are an important source of flavonoids (35.10 ± 1.23 mg RE/g plant material). Qualitative and quantitative 

analyses of the polyphenolic compounds were achieved using a HPLC-UV-MS method. The main flavonoid from the leaves 

was isoquercitrin (2486.18 ± 5.72 μg/g plant material), followed by quercitrin (1645.14 ± 2.12 μg/g plant material)

Regarding the fruit composition, the dominant compound there was rutin (13.02 ± 0.21 μg/g plant material), but 

comparing with the leaves, fruits can be considered a poor source of phenolic compounds. 


The antioxidant activity was evaluated by DPPH, TEAC, hemoglobin ascorbate peroxidase activity inhibition (HAPX),

inhibition of lipid peroxidation catalyzed by cytochrome c and EPR spectroscopic assays, revealing a better antioxidant 

activity for the Schisandra chinensis extract. In the antimicrobial assay, Schisandra chinensis extractS. chinensis leaves extract showed efficient 

activities against the targeted bacteria, being more active than the fruits extract. 


The results suggest the leaves of S. chinensis as a valuable source of antioxidant compounds with significant 

antioxidant activity.
