Optimisation of pressurised liquid extraction of antioxidants from black bamboo leaves.

Highlights: [•] Antioxidants from black bamboo leaves were extracted by PLE. [•] PLE methods were optimised for TP, TF and DPPH radical scavenging activity. [•] Anti-oxidative activities were enhanced 2–4 times by superheated PLE process. [•] Eight phenolics at optimised conditions were identified and assessed. [ABSTRACT FROM AUTHOR]
