Extraction and Analysis of Natural Product in Plant

Abstract

Plants are well known for being a major source of natural compounds, many of them generally considered of biological interest for their antioxidant, anti-inflammatory, antimicrobial or anti-cancerogenic properties [...]

Laccase-Catalyzed Synthesis of Added-Value Polymers from Cork and Grape Extracts

“…Grapes are also rich in numerous phenolic compounds that are distributed in the pulp (10%), seeds (60–70%), and skin (28–35%) . To maximize the valorization of cork/grape waste, several extraction methods, including ultrasonic extraction, supercritical CO 2 extraction, microwave-assisted extraction, and pressured liquid extraction, have been investigated. − The supercritical CO 2 extraction approach was used by Vincent and colleagues to obtain cork extracts . Nevertheless, due to its low polarity, supercritical CO 2 is unsuitable for polar chemical extraction .…”

“…In the last few decades, there have been numerous papers documenting the extraction of active chemicals from cork/grape identifying their health-benefiting properties. − However, the majority of the extractives are composed of phenolic monomers, with known limitations such as low stability and affinity with other substrates, restricting their applicability in the industrial field . Furthermore, investigations of the polymerization of isolated natural chemicals are relatively rare.…”

Added-Value Compounds in Cork By-Products: Methods for Extraction, Identification, and Quantification of Compounds with Pharmaceutical and Cosmetic Interest

“…Some of these drawbacks can be avoided by using modern extraction techniques, such as the aforementioned ones, as they grant higher selectivity, shorter extraction times and lower consumption of organic solvents. Alternatively, one can also use 'greener' solvents, such as water and supercritical fluids [93,94]. The choice of the method for extraction will rely on the properties of the target compounds, the water content of the starting material, and the aims of the overall procedure.…”

The effectiveness of Tamarindus Indica extracts as a metal corrosion inhibitor in various circumstances

“…Hydro-distillation techniques (water distillation, steam distillation, water and steam distillation), hydrolytic maceration followed by distillation, expression and enfleurage (cold fat extraction) can all be used to extract aromatic plants. Headspace trapping, solid phase micro-extraction, protoplast extraction, micro-distillation, thermo-micro-distillation and molecular distillation are just a few of the most recent extraction methods for aromatic plants (Barbero, 2021).…”

“…The separation of medicinally active portions of plant (and animal) tissues using selective solvents and standard procedures is referred to as extraction in the pharmaceutical industry (G amiz-Gracia and Luque de Castro, 2000). Maceration (Gupta and Nagar, 2012), Tambun et al (2021) infusion (Stanciauskaite, et al, 2021) (Barbero, 2021).…”
