Salvia balansae de Noé a have known to be an important source of a huge variety of no toxic bioactive compounds with lack of information hinders exploitation in food and pharmaceutical industries as natural antioxidants. In this work, the phenolic compounds from S. balansae leaves were extracted using an ultrasound-assisted methodology and were separated and identified by HPLC-DAD. The antioxidant activity was evaluated by ABTS, and DPPH scavenging assays, Iron (Fe2+) Chelating ability and reducing power (FRAP) tests. The total phenolic compounds (TPC) and total flavonoids content (TFC) were found with amounts of 49.63 ± 6.31 mg GAE/g DW and 8.14 ± 0.39 mg QE/g DW respectively. The ABTS, DPPH assays and metal chelating ability test demonstrated a higher antioxidant properties with IC50 values of 328.95 ± 5.29 µg/mL, 545.03 ± 3.267 µg/mL and 689.40 ± 0.86 µg/mL respectively. The reducing power at 700 nm increased considerably with concentration. In addition, the HPLC-DAD analysis showed that there were twelve detectable phenolic compounds and the benzoic acid, quercetin, myrecetin, hydroxyflavon, and ascorbic acid have been exclusively identified for the first time in S. balansae leaves extract and are rarely determined in other Salvia L. species. Therefore, these results brought new data about the main phenolic compounds presents in S. balansae leaves extract with a strong antioxidant potential, which will be an alternative source for synthetic compounds.
