Halophytes as source of bioactive phenolic compounds and their potential applications

Area of Science:

• Plant Science
• Biochemistry
• Pharmacology

Background:

• Halophytes exhibit unique metabolic pathways due to extreme salt stress.
• Investigating halophyte metabolites, particularly phenolics, is crucial for understanding their stress tolerance.
• Phenolic compounds are vital in combating oxidative stress in plants.

Approach:

• A comprehensive literature review analyzed phenolic compounds and biological activities in over forty halophyte species.
• Analytical methodologies for determining phenolics in halophytes were reviewed, highlighting HPLC-DAD and HPLC-MS.
• The study evaluated the industrial potential and applications of halophyte-derived phenolics.

Key Points:

• Halophytes biosynthesize a wide array of phenolics with potent antioxidant and antimicrobial activities.
• Plant organ and extraction methods, especially solvent choice, significantly influence phenolic compound profiles.
• High-performance liquid chromatography (HPLC) techniques are predominantly used for phenolics analysis.

Conclusions:

• Halophytes are rich sources of bioactive phenolic compounds.
• These compounds demonstrate significant antioxidant and antimicrobial properties.
• Halophyte phenolics hold considerable promise for diverse industrial applications.
