Abstract
Marine macroalgae are recognized as rich
sources of bioactive compounds, particularly phenolic substances with
significant antioxidant potential. The present study aimed to evaluate the
total phenolic content in selected marine macroalgae from Narara Bet, a
prominent intertidal region of the Gulf of Kachchh, India, and to assess the
influence of species variation and preservation methods on phenolic estimation.
A total of 26 macroalgal species belonging to Chlorophyta, Phaeophyta, and
Rhodophyta were collected. Total phenolic content was determined using Bray
& Thorpe’s method and expressed as mg/g of algal material. Considerable
variation in phenolic content was observed among species, with the highest
values recorded in Acanthophora spicifera (20.59 mg/g) and Sargassum
prismaticum (18.35 mg/g), while comparatively lower values were noted in
species such as Amphiroa fragilissima and Solieria robusta.
Division-wise analysis indicated relatively higher phenolic accumulation in
Rhodophyta. Furthermore, comparative evaluation of preservation methods in
selected species revealed that oven-dried samples generally exhibited higher
phenolic content, followed by fresh samples, whereas freeze-stored samples
showed comparatively lower values. The findings highlight that both species
selection and preservation technique significantly influence the estimation of
total phenolic content in marine macroalgae. This study underscores the
potential of intertidal macroalgae as promising natural sources of phenolic
compounds and emphasizes the importance of appropriate processing methods for
their effective utilization.
