Article Synopsis
- - Three specimens of a plant subspecies were collected in Italy's Abruzzo region for botanical identification and analysis of their essential oils, revealing three distinct chemotypes, including a new one characterized by high levels of (-)-limonen-10-yl-acetate.
- - Despite concerns about genotoxicity from related compounds reported by the EFSA in 2017, tests indicated that the new chemotype (CIV17-EO) showed no mutagenic activity, supporting its safety for use as a flavoring substance.
- - The ethanolic extracts of the plants contained beneficial compounds like caftaric, chlorogenic, and rosmarinic acid, demonstrating significant antioxidant activity and slight cytotoxicity against the A549
The essential oil (EO), the methanolic (MeOH), and the 70% ethanolic (70% EtOH) extracts obtained from the aerial parts of Mill. (Ecuador) were chemically characterized through gas-chromatography coupled to mass spectrometry detector (GC-MS), high-performance liquid chromatography coupled to diode array-mass spectrometry detectors (HPLC-DAD-MS) and studied for their in vitro biological activity. The radical scavenger activity, performed by spectrophotometric 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays, highlighted significant IC values for the EO, extracts and their main constituents (eugenol and rosmarinic acid).
