Tiềm năng các hợp chất chống oxy hóa carotenoid và phenolic của vi tảo (Heamatococcus pluvialis)

Haematococcus pluvialis is a freshwater, green unicellular microalga capable of accumulating high levels of astaxanthin. The capacity to accumulate carotenoid and phenolic antioxidants of H. pluvialis was evaluated when cultured under BBM, OHM, BG11 and MD4 media. The results showed that carotenoid and phenolic contents of H. pluvialis was achieved at high values when cultured in OHM medium. However, phenolic content per cells (pg gallic acid/cell) of H. pluvialis was highest when cultured in MD4 medium. The antioxidant capacity of H. pluvialis was the greatest when grown in OHM. The antioxidant capacity of H. pluvialis showed a positive correlation with carotenoid and phenolic contents when cultured in different media. Thus, H. pluvialis demonstrated the potential of accumulating high carotenoid and phenolic antioxidants when grown in OHM media.

Keywords: Haematococcus pluvialis, carotenoid, phenolic, antioxidant capacity.
