Article Synopsis
- - This study focuses on extracting Schott extracts using supercritical fluid extraction (SFE) with CO₂ at 300 bar and 40°C from mature fruits, resulting in a total fatty acid (FA) content of 795.8 mg/g.
- - The fatty acid profile identified linoleic acid as the most abundant (386 mg/g), followed by oleic, linolenic, palmitic, and stearic acids.
- - Comparative tests showed that SFE extracts and others had no significant antimicrobial activity, while only the methanolic extract demonstrated a 11-mm inhibition against specific bacteria.
This study investigates the chemical composition, nutritional, and biological properties of extracts obtained from berries using different extraction methods and solvents. Hydrodistillation and supercritical fluid extraction with CO allowed us to isolate fruit essential oil (HD) and fixed oil (SFE), respectively. A phenol-enriched extract was obtained using a mild ultrasound-assisted maceration with methanol (UAM).

In a healthy population ( = 231 participants), using bivariate correlations and multivariate linear regression analyses, significant sex differences emerged in quinine bitterness perception, with women showing a higher bitter taste intensity rating than men. Among all participants, 40 subjects (subpopulation) were randomly selected for the evaluation of sex differences in Mirtamaro gustatory and olfactory perception using a hedonic Likert-type scale.

- * This study focused on identifying the chemical composition of the essential oil (EO) sourced from L. by using hydrodistillation and advanced analytical techniques like GC-FID and GC-MS.
- * Findings revealed that the EO not only effectively inhibited the growth of harmful fungi and reduced inflammatory markers, but also demonstrated promising wound healing and anti-aging properties, suggesting its potential for developing eco-friendly skin care products.
Essential oils (EOs) obtained by hydro-distillation from different parts of twigs (EOT), leaves (EOL), and fruits (EOF) of Hook. f. were screened for their chemical composition, insecticidal, repellence, and antibacterial properties.
