Analysis of Polyphenol and Antioxidant Chlorella Vulgaris Extract: Preliminary Study.

Microalgae is an alternative material that can be used for various application in dentistry. Type of microalgae that is easy to obtain is Chlorella Vulgaris which is known have a high protein contents that are useful in forming the new tissues. The present study aimed to analyze the content of polyphenols, antioxidants, and the physical stability of Chlorella Vulgaris gel. Microalgae was collected from sea water, followed by sterilization and screening process to obtain Chlorella Vulgaris seeds. Seeds culturing and extraction was carried out to obtain powder, and then tested for polyphenol content and examined antioxidant activity. Physical stability tests included the dispersion, pH, and viscosity tests of the Chlorella Vulgaris extract gel. one-way and two-way ANOVA were utilized to analyse the data. The results of the phenol content test showed that the antioxidant activity was 0.087% in the chlorella Vulgaris extract. The results of the physical stability test showed a spreadability of 3.9 cm with a pH of 9, and a semisolid, pseudoplastic gel viscosity. Chlorella Vulgaris contains high antioxidant concentration and activity, thus appropriate physical stability to be used to accelerate tissue regeneration. [ABSTRACT FROM AUTHOR]
