The aim of this study was to investigate the main volatiles and polyphenolic compounds in hydrosols extracted from three Romanian Lamiaceae plants, sage (Salvia officinalis), rosemary (Rosmarinus officinalis) and lavender (Lavandula angustifolia) by steam distillation. The antioxidant and acetylcholinesterase inhibition capacity of hydrosols were assessed for their further use as biopesticides. The results have shown that sage and rosemary hydrosols presented better antioxidant activity than lavender hydrosol in all free radical scavenging and metal chelating assays. A strong relationship between the antioxidant activity of hydrosols’ and their total phenolic and flavonoid content was found based on Pearson correlation coefficients. Sage and rosemary hydrosols exerted higher acetylcholinesterase inhibition than lavender hydrosol, but this activity was moderate correlated to phenolic content and low correlated to flavonoid content. These results suggested that volatiles and other compounds present in hydrosols were also involved in this process. In conclusion, Lamiaceae plant hydrosols could be further tested, as such or mixed, as natural products for the control of pests in eco-agrosystems.
