文摘
- •
Pressurised liquid and supercritical fluid extraction applied to Bergenia crassifolia.
- •
Consecutive extraction with increasing polarity solvents produced several fractions.
- •
Root and leaf extracts isolated with polar solvents were strong antioxidants in vitro.
- •
Main phytochemicals were quantified in extracts and plant material by UPLC–MS/MS.
- •
The content of bergenin was many times higher in roots than in leaves.
