摘要：

Crude bio-oil from the brown alga Saccharina japonica was separated into distilled fractions under reduced pressure (40 mmHg). The three bio-oil distillates were depending on temperature (Fraction I; <= 40 degrees C, Fraction II; 40-120 degrees C, Fraction III; 120-160 degrees C, solid residue; b.p. > 160 degrees C). The characteristic of the middle distillates showed that aliphatics (including alkanes) and aromatics (including heterocyclics) were mostly distributed in a dark hydrophobic oil (DHO) of Fractions II and III, while anhydrosugars, acids, ketones and ethers were mainly concentrated in a transparent hydrophilic oil (THO) of Fractions II and III.
