Introduction

The extraction of valuable compounds from bioalgae refers to the process of isolating and purifying bioactive substances present in algae for various applications. In recent years, this extraction process has gained significant attention in the pharmaceutical industry due to the potential therapeutic properties of these compounds.

Types of Valuable Compounds

Bioalgae contain a wide range of valuable compounds that can be extracted for pharmaceutical purposes. Some of the most commonly targeted compounds include:

1. Pigments: Algae are known to produce various pigments such as chlorophyll, carotenoids, and phycobiliproteins. These pigments have antioxidant, anti-inflammatory, and anticancer properties, making them valuable for drug development.

2. Polysaccharides: Algal polysaccharides, such as carrageenan and agar, have been found to possess immunomodulatory, antiviral, and antitumor activities. These compounds can be extracted and used as ingredients in pharmaceutical formulations.

3. Fatty acids: Certain species of algae are rich in omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids have been shown to have cardiovascular benefits and are commonly used in the production of dietary supplements.

4. Proteins and peptides: Algae are a good source of proteins and peptides with potential pharmaceutical applications. These compounds can exhibit antimicrobial, antiviral, and antitumor activities, making them attractive targets for drug development.

Extraction Methods

Several extraction methods are employed to isolate valuable compounds from bioalgae. These methods include:

1. Solvent extraction: This method involves using organic solvents to dissolve the desired compounds from the algal biomass. The solvent is then evaporated to obtain a concentrated extract.

2. Supercritical fluid extraction: In this method, supercritical fluids, such as carbon dioxide, are used as solvents to extract the compounds. Supercritical fluids offer advantages such as high selectivity and low environmental impact.

3. Enzyme-assisted extraction: Enzymes are used to break down the cell walls of algae, facilitating the release of intracellular compounds. This method is often used for the extraction of proteins and polysaccharides.
