“…Tetratriacontane and tetracosane were found with circa 1% of relative concentration, and 8-hexylpentadecane, heptadecane, and hexadecane at lower relative compositions. Hydrocarbon compounds present radical scavenging activity, i.e., antioxidant activity [2], while terpenes (phytol; <0.27%) and sterols (stigmasta-5,22-dien-3-β-ol, acetate and stigmast-5en-ol, oleate; <0.82%) play a role in cosmetic applications as antibacterial, antioxidant, and anti-inflammatory active ingredients [17]. Studies have shown a contribution of phytosterols (sterols obtained from plants) regarding collagen synthesis.…”

“…The higher fatty acid content in Mo leaf SFE-CO 2 extracts obtained in this work compared to the other studies [25,36] may be a consequence of extraction conditions, environmental effects, and agriculture practices. The high unsaturated fatty acid content (linolenic and linoleic acids) makes the Mo leaf extracts a potential alternative for skin hydration and a protective barrier against pollution effects, mainly due to their antioxidant and antimicrobial activities [17].…”

“…The lipidic fraction plays an important role as an active ingredient in topical products, providing high skin hydration and anti-ageing potential [15,16]. Sterols and fatty acids are functional compounds widely used to increase the antioxidant potential of skin care formulations, helping the cream spreadability and creating a barrier against environmental stressors such as UVB radiation [15,17]. Furthermore, Mo seed extracts have been shown to present antibiofilm, antioxidant, and anti-inflammatory effects due the presence of tocopherols and phenolic acid compounds [3,15,18].…”

“…Supercritical extraction using carbon dioxide (SFE-CO 2 ) has been extensively used as an alternative green technology, resulting in extracts with higher compound selectivity, as the extraction yield of a specific compound or group of compounds can be enhanced by tuning the pressure and temperature. Supercritical CO 2 presents diffusion coefficients similar to gases and low viscosities similar to liquids, resulting in a decrease in surface tension and an increase in the solvent penetration into the plant matrix [17]. The extraction ability of CO 2 , a non-polar solvent, can also be enhanced using a co-solvent such as ethanol.…”

Moringa oleifera L. tree (Mo) has emerged as a rich alternative source of bioactive compounds to design cosmetic formulations. Supercritical carbon dioxide fluid extraction (SFE-CO2) was successfully applied on the screening of Mo seed, leaf, and root extracts. The extraction yield was evaluated by response surface methodology (RSM), for pressure and temperature ranges of 117–273 bar and 41–60 °C, respectively, using a design of experiments (DOE). The pressure significantly affected the results (α=0.05), with the highest extraction efficiency obtained at conditions above 195 bar. The extracts’ composition, evaluated by gas chromatography-mass spectrometer (GC-MS), revealed an increasing correlation between the pressure, total extract solubility, and mass of extract at a constant temperature, due to the higher extraction yield. Seed extracts presented more than 80% of oleic acid in relative composition (8.04 mgcompound∙gplantpart−1). Leaf extracts performed well for the obtainment of linolenic acid (>20%; 3.10 mg∙g−1), nonacosane (>22%; 0.46 mg∙g−1), and α-tocopherol (>20%; 0.21 mg∙g−1). Mo root resulted in higher relative composition for sterol molecules, despite its very low affinity with CO2. The most promising bioactive compounds, oleic acid and α-tocopherol, were more abundant when operating at 250 bar at 45 °C and 195 bar at 55 °C, for Mo seed and leaf SFE-CO2 extracts, respectively.

“…These fluids are characterized by their safety, being ecologically friendly and economically viable. SC-CO2 is the most widely used solvent in this context, being preferred in several areas, such as food, cosmetics, pharmaceuticals, and biomedicines, due to its versatility for a variety of applications [16][17][18][19].…”

Polyphenol oxidase (PPO) and peroxidase (POD) are target enzymes in the processing of tender coconut water (TCW). This study primarily evaluated the combined effect of supercritical carbon dioxide (SC-CO2) and mild temperatures on the PPO and POD deactivation of TCW. A factorial design was performed to investigate the effect of temperature (in the range of 35 to 85 °C), pressure (75 to 370 bar), and holding time (13 to 47 min) on the enzymic deactivation, physicochemical parameters, and color of the TCW. The percentages of reduction in PPO activity ranged from 3.7 to 100%, and POD ranged from 43.4 to 100%. The pH values of the freshly extracted and processed TCW were 5.09 and 4.90, and the soluble solids content were 5.5 and 5.4 °Brix, respectively. The holding time (t) had a significant effect (p ≤ 0.1) on the total color variation. As for the reduction of PPO activity, the temperature (T) and the interaction between pressure (P) and t had a significant effect. None of variables (P, T, or t) affected (p > 0.1) the POD reduction, pH, and soluble solids variation. The combination of SC-CO2 and mild temperatures is a promising intervention in the enzymic stabilization of TCW.
