The soxtex immersion and extraction method,soxtex system HT method were used to determine the crude fat content in grain,oil and feed,and were compared with national standard——soxtex immersion method.

The results indicated that the yield of fat extraction was impacted by several factors,and impact degree were as followed:extracting times>soaking time>sample-solvent ratio>.

High purity of citral was obtained by Soxhlet's extraction,and both the yield and purity were increased compared with traditional chemical methods.

In this article,PAHs on the atmospheric particles in a manufacturing district in Xi'an are determined by Soxhlet's extraction and GC/MS.

Determination of Total Se and Se(Ⅳ) in Chinese Herbs by Soxhlet Extraction-Hydride Generation-Atomic Fluorescence Spectrometry;

Study of Soxhlet extraction of polycyclic aromatic hydrocarbons on airborne particulate;

Study on Extracting Trehalose from Beer Waste Yeast with Soxhlet Extraction Method;

With the yield of concentration of sulfur compound as the evaluation index,the contrast between onion essential oil and onion oleoresin from dried onion powder by steam distillation,solvent extraction and Soxhlet method was studied.

Compared with Soxhlet method and supercritical carbon dioxide extraction, microwave extraction of orrisroot is a rapid method (about 120 s) with less solvent consumption (about 160 mL/40g orrisroot),higher yield (about 10%) and better product with good color and aroma.

Methods The chemical components of Propolis(Gansu) extracts separated by Soxhlet extraction method were analyzed comparatively by GC-MS.

Methods: The volatile components extracted from Chinese Propolis by Soxhlet extraction method, Ultrasonic extraction method, Infusion extraction method and Steam-distilled extraction were comparatively analyzed by GC-MS.

Conclusion Soxhlet extraction method is initially assessed to be a suitable extraction method for essential oils from propolis.
