Background and Objectives: The cyanobacterium Spirulina also called blue green algae is a class of gram negative bacteria which possesses wide range of bioactive colored components as Phycocyanin, carotenoids and chlorophyll. Spirulina is one of the microalgae containing nutrients that have been used as a functional food in addition to therapeutic and pharmaceutical applications. This study aimed to evaluate the biochemical composition of Spirulina platensis biomass and its ethanolic and aqueous extracts, as well as, evaluate the antioxidant activities of the biomass, ethanolic, aqueous and the purified Phycocyanin. Materials and Methods: The chemical compositions of Spirulina platensis were determined, as well as the antioxidant activity of extracts, Phycocyanin, Phycocyanopeptide and Phycocyanobilin using (DPPH) radical-scavenging activity. Results: Results show that biomass has higher total proteins (49.72±0.508%), total carbohydrates (10.3±0.330%), moisture content (7.5±0.685%), lipids (7.2±0.105%) and Minerals (6.9±0.130%). In biomass, the total phenols (51.20±0.25 µg/mL) and flavonoids (97.73±1.858 µg/mL) were high compared to the ethanolic (49.48±0.130 and 69.07±1.814 µg/mL) and aqueous (15.27±0.639 and 4.67±0.611 µg/mL) extracts respectively. In the phenolic compounds, pyrogallol was identified as the major compound in biomass and aqueous extract (63.85 and 12.33%) respectively, E-vanillic acid in ethanolic (18.20 %), whereas, hespirdin (3.517 and1.639%) were major flavonoids found in aqueous and ethanolic extracts respectively. The DPPH scavenging activity was found higher in ethanolic extract compared to aqueous while in bioactive, the order of antioxidant activity was Phycocyanin > Phycocyanobilin > Phycocyanopeptide. Conclusions: The study data regarding to Spirulina nutritional value, makes Spirulina an excellent choice when formulating diets and combating malnutrition. Furthermore, it is a strong antioxidant and could be used as alternative treatments as anticancer, antidiabetic, and anti-inflammatory agent.

“…However, in the case of P. tricornutum our comparative experiments have shown a different behavior, with 100% methanol as a better extraction solvent than 96% ethanol. For economic reasons and because Fx is a heat-sensitive molecule [ 53 ], the first tests were carried out at 30 °C for both species. However, increasing the temperature up to 40 °C to enhance Fx extraction [ 51 ] and increasing the extraction duration up to eight hours allowed to reach similar extraction yields from P. tricornutum biomass with 96% ethanol as compared to 100% methanol ( Figure 1 C).…”

Fucoxanthin and Polyunsaturated Fatty Acids Co-Extraction by a Green Process

et al. 2018

By their autotrophic nature and their molecular richness, microalgae are serious assets in the context of current environmental and societal challenges. Some species produce both omega-3 long chain polyunsaturated fatty acids (PUFAs) and xanthophylls, two molecular families widely studied for their bioactivities in the fields of nutrition and cosmetics. Whereas most studies separately deal with the two families, synergies could be exploited with extracts containing both PUFAs and xanthophylls. The purpose of our work was to determine cost effective and eco-friendly parameters for their co-extraction. The effect of several parameters (solvent, solvent/biomass ratio, temperature, duration) were studied, using two microalgal species, the non-calcifying Haptophyta Tisochrysis lutea, and the diatom Phaeodactylum tricornutum, that presents a silicified frustule. Analyses of PUFAs and fucoxanthin (Fx), the main xanthophyll, allowed to compare kinetics and extraction yields between experimental protocols. Co-extraction yields achieved using 96% ethanol as solvent were 100% for Fx and docosahexaenoic acid (DHA) in one hour from T. lutea biomass, and respectively 95% and 89% for Fx and eicosapentaenoic acid (EPA) in eight hours from P. tricornutum. These conditions are compatible with industrial applications.

“…Florotanin, senyawa fenol pada rumput laut cokelat, yang diisolasi dari Fucus vesiculosus diuji stabilitasnya pada berbagai suhu penyimpanan (Kirke et al 2017). Selain faktor-faktor tersebut, perbedaan metode pengolahan/ pre-treatment juga memengaruhi kestabilan pigmen dan total fenol (Susanto et al 2017). Namun sedikit sekali penelitian yang dilakukan untuk efek perbedaan pre-treatment terhadap stabilitas senyawa yang terkandung pada ekstrak rumput laut.…”

“…Proses degradasi akan menghasilkan turunan senyawa fukosantin yaitu 9'-cis Fs, 13cis Fs, dan 13'-cis Fs (Heo et al 2008). Proses perubahan tersebut disebabkan oleh suhu yang tinggi baik pada saat ekstraksi dan saat penyimpanan (Hii et al 2010;Bonn et al 2010;Kawee-ai et al 2013;Susanto et al 2017;Zhao et al 2019) (Yip et al 2014). Salah satu penyebab ketidakstabilan Fs selama penyimpanan adalah adanya ikatan allenik yang menyebabkan stabilitasnya rendah (Zhang et al 2015) Kandungan Total Fenol Ekstrak metanol pada rumput laut cokelat Sargassum mengandung senyawa fenol (Magnusson et al 2017;Puspita et al 2017) antara lain eckol, asam galat, florotanin, katekin, epikatekin, quercetin, dan phlorotannin (Mekini´ et al 2019).…”

Karotenoid, fukosantin dan fenol merupakan senyawa yang terkandung pada rumput laut Sargassum duplicatum. Senyawa-senyawa ini berperan dalam menghambat radikal bebas. Namun, kemampuan penghambatan radikal bebas senyawa ini mempunyai kestabilan yang rendah, terutama terhadap perlakuan suhu. Tujuan penelitian ini adalah untuk menentukan pengaruh pre-treatment suhu tinggi (blanching) dan suhu rendah (pembekuan) serta perlakuan terbaik yang dapat mempertahankan stabilitas senyawa aktif pada ekstrak metanol rumput laut selama penyimpanan. Metode penelitian yang digunakan adalah experimental laboratories menggunakan rancangan acak lengkap (RAL) faktorial 2x5 yaitu pola terbagi menjadi faktor suhu pengolahan (suhu tinggi dan suhu rendah) dan lama penyimpanan (0, 2, 4, 6, dan 8 hari). Blanching dilakukan pada suhu 95 oC sedangkan pembekuan pada suhu -27 oC. Hasil penelitian menunjukkan karotenoid, fukosantin, dan senyawa fenol dengan perlakuan blanching lebih stabil dibandingkan perlakuan pembekuan. Berdasarkan hasil penelitian menunjukkan bahwa adanya interaksi antara pre-treatments dan lama penyimpanan yang berpengaruh nyata terhadap nilai total karotenoid, kandungan fukosantin, total kandungan fenol, dan nilai perubahan warna (ΔE).
