“…The total triterpenoids of S. sphenanthera in the FS and GFS had the best antibacterial effect on S. aureus (Figure 6C,D). In addition to B. subtilis, which can be used as probiotics [49], the other three bacteria are pathogenic [50][51][52][53]. While symbiotic E. coli is a normal part of the gut microbiota of a healthy host, E. coli O157 is both zoonotic and pathogenic [50].…”

While symbiotic E. coli is a normal part of the gut microbiota of a healthy host, E. coli O157 is both zoonotic and pathogenic [50]. S. aureus is a widely used and widespread harmful pathogen, which can cause a variety of invasive diseases such as endometritis and osteomyelitis, and is also considered to be the main pathogen of acute lung injury [51,52].…”

Schisandra sphenanthera Rehd. et Wils., as a traditional Chinese medicine, has important medicinal value. In the market, the availability of the fruit of S. sphenanthera mainly relies on wild picking, but many canes and leaves are discarded during wild collection, resulting in a waste of resources. The canes and leaves of S. sphenanthera contain various bioactive ingredients and can be used as spice, tea, and medicine and so present great utilization opportunities. Therefore, it is helpful to explore the effective components and biological activities of the canes and leaves to utilize S. sphenanthera fully. In this study, the response surface method with ultrasound was used to extract the total triterpenoids from the canes and leaves of S. sphenanthera at different stages. The content of total triterpenoids in the leaves at different stages was higher than that in the canes. The total triterpenoids in the canes and leaves had strong antioxidant and antibacterial abilities. At the same time, the antibacterial activity of the total triterpenoids against Bacillus subtilis and Pseudomonas aeruginosa was stronger than that against Staphylococcus aureus and Escherichia coli. This study provides the foundation for the development and utilization of the canes and leaves that would relieve the shortage of fruit resources of S. sphenanthera.
