Seaweed Extraction

A study in J. Chromatography reported on the SeparationsNow website studied three methods of separating essential oils from a crude ether extract of the brown seaweed Dictyopteris membranacea. The methods hydrodistillation (HD), microwave-assisted hydrodistillation (FMAHD) and supercritical fluid extraction (SFE) obtained similar yields of oil, but interestingly, the FMAHD process produced more sesquiterpenes, which have a lower volatility.

SeparationsNow is published by John Wiley & Sons dedicated to sample preparation, Electrophoresis, GC, HPLC and other chemical separation processes. I looked in their archives for other relevant articles, but didn't find any recent ones.
