Abstract
Schisandra chinensis (Turcz.) Baill. is an important traditional medicinal plant. Lignans, the main active components of S. chinensis, have pharmacological effects, including liver protection, antioxidant, and anticancer properties. In this study, we investigated the dynamic changes and differences in appearance quality, contents of key lignan compounds, and antioxidant capacity of three S. chinensis varieties during the ripening of fruits and seeds. The lignan content in the seeds of the three varieties reached up to 91.9%, it showed an ‘M’-type trend of ‘increase–decrease–increase–decrease’ during fruit ripening; this lignan content was significantly higher than that measured in the fruit. The antioxidant capacity of the seeds surpassed that of the grains, and the maturation trends of the grains and seeds remained relatively aligned. The overall change in free radical (DPPH)-scavenging ability in the seeds during ripening exhibited an inverted ‘N’-type trend of ‘decrease–increase–decrease’. The trends in TFC and TPC were consistent with this ‘N’-type pattern of ‘increase–decrease–increase’. In summary, our results suggest 104 days after flowering as the best harvesting period for S. chinensis. Additionally, this study elucidates the synthesis patterns of lignan content and the corresponding changes in antioxidant capacity in S. chinensis, thereby providing a foundation for the evaluation and screening of germplasm resources.
