Phenolic and flavonoid content and antioxidants capacity of pressurized liquid extraction and perculation method from roots of Scutellaria pinnatifida A. Hamilt. subsp alpina (Bornm) Rech. f.

- The extract was separated from Scutellaria pinnatifida using perculation and PLE.
- The independent parameters were optimized using circumscribed central composite.
- The highest antioxidant activity was observed from the PLE extract.
- The PLE method is quicker and it has more extraction yield than perculation.
