Extraction of Astaxantine and Phycocyanine from Microalgae with Supercritical Carbon Dioxide (original) (raw)

Journal of Chemical and Engineering Data, 2003

Abstract

Astaxantine from the microalga Haematococcus pluvialis and phycocyanine from the microalga Spirulina maxima have been obtained by supercritical extraction using carbon dioxide. Prior to extraction, the samples of microalgae were crushed by cutting mills (coffee mill) and then manually ground with dry ice (solid carbon dioxide). The Haematococcus extracts were analyzed by liquid chromatography, using astaxantin (purity of 98%) as
