Detection of some Active Phenolic Compounds in Two Local Microalgae Species Chlorella Sorokiniana Shihira & R.W.Krauss and Coelastrella Saipanensis N.Hanagata

The present study aimed to characterise some active phenolic compounds in the alcoholic extract of two types of local microalgae, Chlorella sorokiniana Shihira & R.W.Krauss and Coelastrella saipanensis N.Hanagata These compounds were detected using HPLC device. The results showed that there were four types of active phenolic compounds, which were Gallic acid, Catechine, Ferulic acid and Hydrobenzoic acid. The highest concentration of all these compounds  found in Coelastrella saipanensis. Concerning the compounds, the highest value was for Gallic acid and it was ۴۵. ۸۵ ppm, while the lowest value was for Hydrobenzoic acid and it was ۱۴. ۲۸ ppm in Chlorella sorokiniana. It is that these compounds have vital activity in inhibiting different types of pathogenic bacteria and fungi as shown in many previous studies. From this study, we conclude the ability to produce these active compounds from both algae under natural conditions of growth.
