Comparative Study of Bioactive Substances Extracted from Fresh and Dried Spirulina sp.

Abstract

The increase consumption of natural substances has brought about in increasing demand on biological source, including Spirulina sp. This Spirulina sp. has been recognized to provide some natural substances such as natural colorant, source of vitamins, protein and some minerals. Different material state of Spirulina sp. in the form of fresh and dried form may cause different quantity and quality of natural substances in microalgae which posses a wide range of change including nutritional and natural substances. The aims of the study was to investigate the bioactive compounds resulted from different form of Spirulian sp (fresh and dried) quantitatively. The materials used were fresh and dried Spirulina sp which was extracted by ethanol. Analysis were subjected for phytochemical screening, flavoniod, phenolic acid and antioxidant activity (DPPH scavenging activity). The results showed that total flavonoid of fresh and dried are: 25.6615±1.62 and 110.1356±12.5 quercetin/gr extract ; phenolic acid : 2.117±0.99 and 6.92±0.03 GAE/gr extract; IC50 : 33.0755, respectively. Fresh sample of Spirulina platensis shows better results in bioactive compounds quantitatively and qualitatively compared to that of dried sample, and drying process at 40-50 o C does not give any significant different on nutritional quality of dried sample of Spirulina platensis compared to fresh samples.

Spray-dried Spirulina platensis as an effective ingredient to improve yogurt formulations: Testing different encapsulating solutions

“…This nutritional composition corresponded to an energetic value of 378 ± 1 kcal/100 g dw. In general, these results corroborate previous reports on the nutritional composition of Spirulina platensis (Agustini, Suzery, Sutrisnanto, Maruf, & Hadiyanto, 2015;Sharoba, 2014), and are in accordance with the ones reported in the commercial label.…”

Functional Composition, Nutritional Properties, and Biological Activities of MoroccanSpirulinaMicroalga

“…In this study, the EC50 was 23 μg/ml, indicating a very high antioxidant potential [72]. Both the lower EC50 and the higher DPPH activity were related to a high antioxidant activity [73]. e study has been carried out on the DPPH-scavenging activity of the Spirulina extract compared to both vitamins C and E which showed that EC50 was about 40 ppm; i.e., one is better than the other which is comparable, as shown in [71].…”

Natural remedies for non‐steroidal anti‐inflammatory drug‐induced toxicity

“…Spirulina is also rich in non-essential amino acids such as: alanine (5.82%; helps in the strengthening of the cell wall); arginine (5.98%; helps in cleaning the blood); aspartic acid (6.34%; helps to transform carbohydrate into energy); cystine (0.67%; maintains a healthy pancreas and blood glucose level); glutamic acid (8.94%; controls healthy mental function); glycine (3.5%; enhances energy); histidine (1.08%; helps in improving auditory nerves); proline (2.97%; reduces alcohol content in the body); serine (4%; helps to produce improved fatty protection); and tyrosine (4.6%; reduces the process of aging, produces color to the body and protects the body from sun radiation) (Abdel-Tawwab et al, 2008;Agustini et al, 2015;Vo et al, 2015).…”
