3. Traditional Methods of Peptide Extraction

Peptide extraction from plants has been a subject of interest for many years due to the potential therapeutic and nutritional benefits of these bioactive compounds. Traditional methods of peptide extraction have been developed and utilized to harness these valuable components from plant sources. Here, we discuss some of the most commonly used traditional techniques in the extraction of peptides from plants.

3.1 Maceration
Maceration is a simple and widely used method for extracting peptides from plant materials. It involves soaking the plant material in a solvent, typically water or a mixture of water and an organic solvent, for an extended period. The solvent penetrates the plant tissue, dissolving the peptides and other soluble components. The mixture is then filtered to separate the liquid containing the extracted peptides from the solid plant residue.

3.2 Enzymatic Hydrolysis
Enzymatic hydrolysis is another traditional method that involves the use of enzymes to break down proteins into smaller peptides. Plant materials are first ground into a fine powder and then mixed with an enzyme solution. The enzymes cleave the peptide bonds, releasing the peptides into the solution. This method is advantageous because it can be tailored to target specific peptide sequences, and it is relatively mild, preserving the bioactivity of the peptides.

3.3 Acid or Alkaline Hydrolysis
Acid or alkaline hydrolysis involves the use of strong acids or bases to break down proteins into peptides. This method is less specific than enzymatic hydrolysis and can result in the formation of undesirable by-products. However, it is a simple and cost-effective approach that has been used for many years in the extraction of peptides from plants.

3.4 Ultrasonication-Assisted Extraction
Ultrasonication-assisted extraction is a technique that uses ultrasonic waves to disrupt plant cell walls and release peptides into the solvent. This method is more efficient than maceration, as it reduces the extraction time and improves the yield of peptides. The high-frequency vibrations generated by the ultrasonic waves create micro-cavitation bubbles that break open the plant cells, allowing for the extraction of peptides.

3.5 Solid-Phase Extraction
Solid-phase extraction (SPE) is a technique that uses a solid support material to selectively adsorb peptides from a liquid sample. The plant extract is passed through a column packed with the solid support material, which selectively binds the peptides. The unbound components are washed away, and the peptides are then eluted using a suitable solvent. SPE is a versatile method that can be used to purify and concentrate peptides from plant extracts.

3.6 Limitations of Traditional Methods
While traditional methods of peptide extraction have been widely used, they also have some limitations. These include low extraction efficiency, long extraction times, and the potential for peptide degradation or modification during the extraction process. Additionally, some methods may require the use of large volumes of solvents, which can be costly and environmentally unfriendly.

In conclusion, traditional methods of peptide extraction have played a significant role in the study and utilization of plant-derived peptides. However, as the field advances, there is a growing need for more efficient and environmentally friendly techniques to improve the extraction process. Modern techniques, as discussed in the following sections, offer promising alternatives to overcome the limitations of traditional methods.

HPLC is particularly useful for its high resolution and speed, allowing for the precise isolation of specific peptides.

4.2 Ultrafiltration

Ultrafiltration is a membrane-based separation process that uses pressure to drive a solution through a semipermeable membrane with defined pore sizes. This technique is effective for concentrating peptides and separating them from larger proteins and other molecules based on their molecular weight. Ultrafiltration is scalable and can be integrated into larger purification processes.

4.3 Solid-Phase Extraction (SPE)

Solid-Phase Extraction involves the use of a solid sorbent to selectively adsorb peptides from a liquid sample. After adsorption, the peptides can be eluted using a suitable solvent, effectively separating them from other components in the sample. SPE is customizable with various sorbent materials, allowing for tailored peptide extraction based on specific chemical properties.

4.4 Enzymatic Hydrolysis

Enzymatic hydrolysis employs enzymes to break down plant proteins into smaller peptides. This method is advantageous for its specificity and mild conditions, which help preserve the integrity of the peptides. Specific enzymes can be chosen to target certain peptide sequences, enhancing the extraction of desired bioactive peptides.

4.5 Sonication and Ultrasonication

Sonication and ultrasonication use sound waves to disrupt plant cell walls and release peptides. This method is non-invasive and can be used to improve the efficiency of peptide extraction by increasing the accessibility of enzymes or solvents to the peptide substrates within the plant material.

4.6 Microwave-Assisted Extraction (MAE)

Microwave-Assisted Extraction leverages microwave energy to heat solvents, which can accelerate the extraction process. MAE is known for its short extraction times and high extraction efficiency, making it a popular choice for rapid peptide isolation.

4.7 Supercritical Fluid Extraction (SFE)

Supercritical Fluid Extraction uses supercritical fluids, such as carbon dioxide, which have properties between liquids and gases, to extract peptides. The advantages of SFE include its non-toxic and environmentally friendly nature, as well as its ability to selectively extract compounds based on their solubility in the supercritical fluid.
