| Abstract: | Known only in phaeophyceae, phlorotannins (brown algal polyphenols) are natural products with potential uses in pharmacology. This study yielded an extraction procedure to obtain high purity,high purity, high molecular weight phlorotannins from Sargassum kjellmanianum, and revealed the characteristics of their infrared and flourescence spectra. The antioxidative activity of phlorotannins, which was about 2.6 times as strongas that of 0.02% BHT (tert - butyl - 4 - hydroxytoluen). showed potential for preventing oil rancidification. |
