To elaborate a complete extraction protocol for the enhanced release of biologically active compounds from plant cells, this study aimed to optimize together the parameters of the supercritical fluid extraction (SFE) process (temperature, pressure, and percentage of cosolvent) and enzymatic treatment of plant material (pH, enzyme concentration, time, and temperature) by response surface methodology (RSM). Medicago sativa L. was selected as a plant material due to its richness in phenolics and flavonoids. HPLC-MS/MS analysis allowed evaluating the content of individual bioactive compounds in obtained extracts. The total content of polyphenolic compounds in the extract obtained after two-step optimization was much higher (546 ± 21 µg/g) than in the extract obtained from non-hydrolyzed material (275 ± 23 µg/g) and in the extract obtained by maceration (162 ± 20 µg/g). Furthermore, it was evidenced that extract with the highest content of polyphenolic compounds can support the cellular antioxidant system both as a free radical scavenger and by stimulating the antioxidant enzyme system.

“…In recent experiments with beetroot leaves for the extraction of polyphenols, it was found that increasing the pressure increased the extraction kinetics. The researchers attributed this improvement in extraction thanks to the increase in fluid density [ 139 ]. However, temperature has a major effect in the extraction than flow rate and pressure.…”

The flavonoids are compounds synthesized by plants, and they have properties such as antioxidant, anticancer, anti-inflammatory, and antibacterial, among others. One of the most important bioactive properties of flavonoids is their antioxidant effect. Synthetic antioxidants have side toxic effects whilst natural antioxidants, such as flavonoids from natural sources, have relatively low toxicity. Therefore, it is important to incorporate flavonoids derived from natural sources in several products such as foods, cosmetics, and drugs. For this reason, there is currently a need to extract flavonoids from plant resources. In this review are described the most important parameters involved in the extraction of flavonoids by unconventional methods such as ultrasound, pressurized liquid extraction, mechanochemical, high hydrostatic pressure, supercritical fluid, negative pressure cavitation, intensification of vaporization by decompression to the vacuum, microwave, infrared, pulsed electric field, high-voltage electrical discharges, and enzyme-assisted extraction. There are no unified operation conditions to achieve high yields and purity. Notwithstanding, progress has been achieved in the development of more advanced and environmentally friendly methods of extraction. Although in literature are found important advances, a complete understanding of the extraction process in each of the unconventional techniques is needed to determine the thermodynamic and kinetic mechanisms that govern each of the techniques.

“…The highest 38.8% of reported data were flavonoids. Other reported compounds were non-flavonoid polyphenols 8.4%, Terpenes and derivatives 8.2%, fat and fatty related compounds 6.4% and glucosinolates and breakdown products 5.6% 4,25,26,27 . A specific aliphatic glucosinolate (GSL), Glucoraphasatin (GRH) is that is only abundant in radish.…”

Radish (Raphanus Sativus) used against many toxicants as a natural drug, is a worldwide grown cruciferous root crop with root part the main edible organ and leave part, which in dried form are effective as functional foods. Radish (Raphanus Sativus) that exhibits variety of colors has rich content of vitamins, phenolic compounds, dietary fiber and Phyto-anthocyanin. Based on physico-chemical, nutritional, antioxidant and microbiological properties radish leaves are more nutritionally rich than roots. Leaves are premier source of phenol, flavonoid and have free radical hunting ability. The antioxidant biomarker compound Rutin has been identified only in radish leaves. Therefore the inclusion of Radish leaves in the human diet could have higher bioactive compounds especially flavonoid availability than roots. Conclusion: Consumption of radish leaves mostly discarded may present nutritional and medicinal value to human health especially due to their Antioxidant Activity. Moreover to develop novel functional products more exploration is required to approximate other bioactive compounds from the radish leaves. Keywords: Radish (Raphanus Sativus), bioactive compounds Antioxidants and Skin
