EVALUATION OF RECOVERABLE FUNCTIONAL LIPID COMPONENTS OF SEVERAL BROWN SEAWEEDS (PHAEOPHYTA) FROM JAPAN WITH SPECIAL REFERENCE TO FUCOXANTHIN AND FUCOSTEROL CONTENTS¹

Abstract

Fucoxanthin (Fx) and fucosterol (Fs) are characteristic lipid components of brown seaweeds that afford several health benefits to humans. This article describes the quantitative evaluation of lipids of 15 species of brown seaweeds with specific reference to Fx, Fs, and functional long-chain omega-6/omega-3 polyunsaturated fatty acids (PUFAs). In addition, fatty-acid composition of selected species was also accomplished in the study. Major omega-3 PUFAs in the brown seaweeds analyzed were α-linolenic acid (18:3n-3), octadecatetraenoic acid (18:4n-3), arachidonic acid (20:4n-6), and eicosapentaenoic acid (20:5n-3). Both Fx (mg · g(-1) dry weight [dwt]) and Fs (mg · g(-1) dwt) were determined to be relatively abundant in Sargassum horneri (Turner) C. Agardh (Fx, 3.7 ± 1.6; Fs, 13.4 ± 4.4) and Cystoseira hakodatensis (Yendo) Fensholt (Fx, 2.4 ± 0.9; Fs, 8.9 ± 2.0), as compared with other brown seaweed species. Studies related to seasonal variation in Fx, Fs, and total lipids of six brown algae [S. horneri, C. hakodatensis, Sargassum fusiforme (Harv.) Setch., Sargassum thunbergii (Mertens ex Roth) Kuntze, Analipus japonicus (Harv.) M. J. Wynne, and Melanosiphon intestinalis (D. A. Saunders) M. J. Wynne] indicated that these functional lipid components reached maximum during the period between January and March. The functional lipid components present in these seaweeds have the potential for application as nutraceuticals and novel functional ingredients after their recovery.

Seasonal Composition of Lipids, Fatty Acids Pigments in the Brown Alga <i>Sargassum pallidum</i>: The Potential for Health

“…At the same time, nearly the same content free sterols in S. pallidum in the winter and summer was shown earlier [43]. As was noted, in seaweeds of genus Sargassum the percentage of one of the dominant sterols as fucosterol was higher in winter and spring [39].…”

“…In Sargassum sp. of the Sea of Japan amounts of fucoxanthin varied from 3.4 up to 5.9% of total lipids [39]. In S. pallidum, it changed from March to December in the range of 6.0% -9.3% with maximum in summer months and early au-tumn (Table 1).…”

“…Five Sargassum sp. of the coast of Japan contain 27.5 -62.6 mg/g TL on DW [39]. The study of seasonal changes in TL content in thalii of S. horneri from different habitats of Japan showed an increase in their content from October to January, a slight decrease in April and a further decline in their level until June.…”

Characteristics and consumer acceptance of healthier meat and meat product formulations—a review

“…Marine oil (seaweed, fish), rich in highly unsaturated fatty acids are responsible for many beneficial effects like hypocholesterolemic, anticarcinogenicity, antimutagenicity, antioxidative and antiaging activity, rheumatoid arthritis, and inflammatory bowel diseases (Kim and Mendis 2006;Terasaki et al 2009). They can as well be incorporated into a variety of products (Table 2) as well as infant formula to improve the functionality of infant food (Nimish et al 2011).…”
