Triterpenes and triterpene glucosides with their oxidative stress injury protective activity from Rubus lambertianus

- Five new 18,19-secoursane triterpene derivatives were isolated from Rubus lambertianus.
- The 18,19-secoursane triterpenes are rarely found previously.
- Seven compounds could protect HUVECs against oxidative damage.
- This is first report of phytochemical research on R. lambertianus.
