Antioxidant and enzyme-inhibitory activity of peppermint extracts and essential oils obtained by conventional and emerging extraction techniques

Toplam 130 atıf DOI
Peppermint is widely used medicinal plant with distinguished bioactive potential, therefore, the aim of present work was to develop novel peppermint extracts with high activity by application of traditional and emerging separation techniques. Conventional hydrodistillation and microwave-assisted hydrodistillation (MWHD) were applied for recovery of essential oil (EO), while organic solvent extraction using Soxhlet apparatus, microwave-assisted and ultrasound-assisted process and supercritical fluid extraction (SFE) were applied for non-selective recovery of peppermint lipophilic extracts. Extracts were characterized in terms of terpenoids profile with special emphasis on content of major compounds (mentol, menthone, isomenthol and eucalyptol). Antioxidant activity (DPPH, ABTS, CUPRAC, FRAP, chelating and phosphomolybdenum assay) and enzyme-inhibitory assays (acetylcholinesterase, butyrylcholinesterase, tyrosinase, amylase and glucosidase inhibition) were used for screening of peppermint bioactivity. MWHD was recognized as alternative for traditional process in EO recovery, while SFE extracts were useful for green production of solvent-free peppermint extracts rich in terpenoids and other lipophilic bioactives.

The influence of drying and extraction processes on the phytochemical composition and biopotential of elderberry is challenging for the food industry. For this reason in this research two drying techniques (lyophilization and natural convection) and three extraction techniques (ultrasound (UAE), microwave (MAE), and conventional (maceration (MAC)) was applied using two”green” solvents (water and 50 % ethanol). Results of the research showed that lyophilization was a better way of drying than natural convection, while MAE extraction was the most efficient technique for the isolation of secondary metabolites. The most abundant phenolic compounds established by LC-MS/MS analysis, were chlorogenic acid and rutin, identified in extracts of lyophilized elderberries. Elderberry extracts achieved great antioxidant (CUPRAC: 2.30–5.13 mg TE/mL) and enzyme inhibitor potential (α-amylase: 0.51–8.34 mg ACAE/mL). The results suggest that elderberry is a rich natural source of bioactive compounds and could be used for the future development of dietary supplements and functional foods.
