Assessment of phytochemical components, proximate composition and antioxidant properties of Scenedesmus obliquus, Chlorella vulgaris and Spirulina platensis algae extracts
Open accessAbstract
In recent decades, natural antioxidant alternatives have become a trending topic for replacing artificial antioxidants. Microalgae have been reported to display interesting bioactive properties and their antioxidant activity is one of them. This study aims to evaluate the antioxidant capacity, phytochemical constituents and proximate composition of three microalgae Scenedesmus obliquus, Chlorella vulgaris and Spirulina platensis. The performed preliminary phytochemical analysis of the algae extracts revealed that they contain good amounts of bioactive compounds. The results showed that the highest total antioxidant activity found was (3720.67 mgAAE/100g) in Spirulina platensis, followed by Chlorella vulgaris (2794.80 mgAAE/100g). The lowest activity was noticed for Scenedesmus obliquus (1718.53 mgAAE/100g). As for total phenolic content, Spirulina recorded the highest phenolic content (2238.46 mgGAE/Kg.), followed by Chlorella (710.33mg GAE/Kg.), and then Scenedesmus (511.20 mgGAE/Kg). The total flavonoids content of algal extracts expressed as mgQE/Kg varied from (548.66) for Chlorella vulgaris, (142.23) for Spirulina platensis to (66.56) for Scenedesmus obliquus. The proximate analysis results indicated high values of protein for Spirulina platensis (53.30 % dry wt.) whereas the highest fat, ash and moisture percentages were recorded by Scenedesmus obliquus (15.13, 15.07 and 2.57, respectively).

“According to the findings of El-Chaghaby et al. [82], the protein content of spirulina platensis was 53.30% (dry weight), which was much higher than that of Chlorella vulgaris (20.67%) and Scenedesmus obliquus (31.07%).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
