Intensification of extraction process through IVDV pretreatment from leaves and stems: Maximizing yields and assessing biological activities.

"Intensification of Vaporization by Decompression to the Vacuum" (IVDV) has initially emerged as a technology primarily employed for expanding and enhancing the texture of biological products. However, its recent applications have showcased significant promise in the realm of extracting bioactive molecules from various plant materials. In this context, optimization using response surface methodology was conducted to investigate the impact of IVDV pretreatment on the extractability of phenolic compounds from leaves and stems, as well as their biological activities.

Chemical Composition and Biological Activities of Stems Extracts Recovered Using , an Innovative Infrared Technology, Compared to Water Bath and Ultrasound.

Extraction of polyphenols from stems was conducted using ultrasound and infrared techniques, and compared to the conventional water bath method. Response surface methodology was used to analyse the effect of time, temperature, and ethanol percentage, as well as to optimize the three extraction methods. The highest phenolic content (81 mg GAE/g DM) and antioxidant activity (76% DPPH inhibition) were recorded with the extract obtained under the optimal conditions: 55 °C, 127 min, 48% (/) ethanol.

Intensification of Polyphenols Extraction from Leaves Using and Evaluation of Antibiofilm and Antibacterial Activities.

(1) Background: is a plant medicinally valued, and used in pharmacopeia to treat various diseases. No previous studies have been reported on leaf extracts using an IR-assisted technique; thus, this study aimed to intensify polyphenol extraction using , comparing it to the conventional water bath (WB) method. (2) Methods: Optimization of polyphenol extraction from leaves was conducted using Response Surface Methodology.
