Abstract
Fucales are an order within the Phaeophyceae that include most of the common littoral seaweeds in temperate and subtropical coastal regions. Many species of this order have long been a part of human culture with applications as food, feedand remedies in folk medicine. Apart from their high nutritional value, these seaweeds are also a well-known reservoir of multiple bioactive compounds with great industrial interest. Among them, phlorotannins, a unique and diverse class of brown algae-exclusive phenolics, have gathered much attention during the last few years due to their numerous potential health benefits. However, due to their complex structural features, combined with the scarcity of standards, it poses a great challenge to the identification and characterization of these compounds, at least with the technology currently available. Nevertheless, much effort has been taken towards the elucidation of the structural features of phlorotannins, which have resulted in relevant insights into the chemistry of these compounds. In this context, this review addresses the major contributions and technological advances in the field of phlorotannins extraction and characterization, with a particular focus on Fucales.

Algal Phlorotannins as Novel Antibacterial Agents with Reference to the Antioxidant Modulation: Current Advances and Future Directions. Mar Drugs 2022; 20:403. [PMID: 35736206 PMCID: PMC9228090 DOI: 10.3390/md20060403] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 06/14/2022] [Accepted: 06/16/2022] [Indexed: 01/27/2023] Open
Abstract
The increasing drug resistance of infectious microorganisms is considered a primary concern of global health care. The screening and identification of natural compounds with antibacterial properties have gained immense popularity in recent times. It has previously been shown that several bioactive compounds derived from marine algae exhibit antibacterial activity. Similarly, polyphenolic compounds are generally known to possess promising antibacterial capacity, among other capacities. Phlorotannins (PTs), an important group of algae-derived polyphenolic compounds, have been considered potent antibacterial agents both as single drug entities and in combination with commercially available antibacterial drugs. In this context, this article reviews the antibacterial properties of polyphenols in brown algae, with particular reference to PTs. Cell death through various molecular modes of action and the specific inhibition of biofilm formation by PTs were the key discussion of this review. The synergy between drugs was also discussed in light of the potential use of PTs as adjuvants in the pharmacological antibacterial treatment.

Zhang X, Guo X, Zhao P, Zhang X, Gao W, Li X. Chemometric analysis of active compounds and antioxidant and α-glucosidase inhibitory activities for the quality evaluation of licorice from different origins. Biomed Chromatogr 2021; 35:e5215. [PMID: 34269469 DOI: 10.1002/bmc.5215] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 06/27/2021] [Accepted: 07/09/2021] [Indexed: 11/07/2022]
Abstract
Contents of total flavonoids (TFc), total phenolics (TPc), and total crude polysaccharide (TCPc) in licorice from different origins were determined by optimized colorimetric methods, whereas five monomer ingredients (liquiritin [LQ], isoliquiritin [ILQ], liquiritigenin [LQG], isoliquiritigenin [ILQG], and glycyrrhizic acid [GA]) were simultaneously identified and quantified by HPLC-MS and HPLC. The results indicated that the contents of chemical compounds in licorice showed significant difference in different origins. Hierarchical cluster analysis and principal component analysis further proved that producing area indeed affected the quality including compounds and pharmacological activity in licorice. Licorice from Inner Mongolia exhibited the excellent DPPH assay, whereas samples from Gansu and Xinjiang showed high scavenging capacity to OH and ABTS free radicals. Meanwhile, α-Glu inhibitory activity of licorice samples was four times higher than the antioxidant activity. Correlation analysis made clear that TFc and TCPc both strongly contribute to DPPH scavenge capacity at P < 0.01 level, whereas TCPc contributed to α-Glu inhibitory activity at P < 0.05 level. This study would contribute to the comprehensive quality evaluation based on the compounds and pharmacological activity of licorice, and provide a reference for the choice of producing area to ensure the quality of licorice as a medicine.
