Oil extracted from the seeds ofCaesalpinia spinosa(common name: tara) can be used in a number of applications. In the present study, tara seed oil was obtained by ultrasonic extraction. The effects of different solvents, particle sizes in the ground seed samples, extraction times, ultrasonication powers, extraction temperatures, and liquid–solid ratios on the yield of tara seed oil were investigated. The yield from the ultrasonic extraction was compared with that from traditional Soxhlet extraction. The results showed that ultrasonic extraction could be completed in a shorter time with reduced solvent consumption. The yield of tara seed oil increased with increasing ultrasonication power and extraction temperature. Gas chromatography was used to analyze the fatty acid compositions of the oils extracted by the two methods. The fatty acid compositions of the oils from both extraction methods were similar, which indicates that ultrasonic extraction is a viable alternative means of extraction. It is a rapid, efficient, and simple method for production of lipids from tara seeds.

The skin of swangi fish is a potential fish skin to be produced for fish oil. The objectives of this research were aimed to determine the yield and the best quality of fish oil and also to compare fatty acid profile of the fish according to different extraction methods. Fish oil extractions were used by wet rendering method with extraction temperatures of 60, 70, 80, 90, 100°C for 20, 30, and 40 minutes. Fish oil quality was determined by the chemical oil characteristics i.e. PV, FFA, AV, anisidin, and TOTOX. Fatty acid profile was analyzed using gas chromatography (Shimadzu). The results of the study showed that the highest fish oil yield in each treatment was obtained extraction temperature of 60°C for 30 minutes with percentage of 0.33, (70°C for 30 minutes) 0.46, (80°C for 30 minutes) 1.23, (90°C for 20 minutes) 1.14 and (100°C for 20 minutes) 0.84. These values were lower compare to Bligh &amp; Dyer and Soxhlet methods. Then, the best fish oil quality was resulted on temperature extraction of 60°C for 30 minutes with PV, FFA, anisidin, AV, and TOTOX were 9.17 meq/kg, 6.92%, 13,77 mg KOH/g, 0.86 meq/kg and 19.19 meq/kg, respectively. FUFA fatty acid compositions of swangi skin fish oil especially EPA and DHA in wet rendering method were gained 0.73% and 2.53%, respectively. These results were lower than Bligh &amp; Dyer method which was consisted of 3.66% (EPA), and 13.29% (DHA) and also Soxhlet extraction method with value of EPA was 2.78% and DHA was 9.62%.<br />Keywords: EPA, extraction temperature, DHA, fish oil quality, fish skin

To compare the extraction rate of the organic components of coal between direct ultrasonic extraction and traditional soxhlet extraction, samples were selected from tectonic coal and original bituminous coal in Pingdingshan 8th coal mine and 5th coal mine. Compared the extraction time of two different extraction methods under the same extraction rate, the experimental results showed that the direct ultrasonic extraction rate was 3.6942% under the condition that coal was 8th coal mine tectonic coal, solvent was pyridine, extraction time was 6min and solvent volume was 60mL, while soxhlet extraction time was 14.59h in the same extraction rate. The extraction efficiency of the direct ultrasonic extraction was 145.9 times that of the soxhlet extraction. The ultrasonic extraction was a simplify working with fast extraction speed, sample capacity, energy saving, economy and environmental friendly. It also didn’t require heating which could avoid the influence of high-temperature on components extracted.

The paper discusses the role of ultrasonic time, ultrasonic power, solid-liquid ratio and extraction temperature on the extraction yield of coix seed, the results show that: with the increase of extraction time, extraction temperature with increasing rates of coix seed polysaccharides upward trend, coix seed polysaccharides first increased and then decreased with the increase of the amount of solvent, coix seed polysaccharides and first increased and then leveled off with the ultrasonic power increases, coix seed polysaccharides first increased and then decreased. Compared with conventional extraction methods, ultrasonic extraction of polysaccharides coix seed is fast, solvent savings, save time, extraction rate and so on.

Paeonia ostii is recognized as an important oilseed tree peony species with potential as a raw material source for cosmetic and health care products, strong seed setting capacity, high seed oil yield, and abundant omega-3 polyunsaturated fatty acids. P. ostii, commonly called Fengdan, is widely cultivated in China. The cultivation method difference has an important influence on the oil-use feature, which is a key index for evaluating the quality of oilseed crops. This study aimed to select an optimal cultivation method to provide the first reference data for high-yield and high-quality seed oil harvesting and to facilitate the understanding of the quality difference in the formation mechanism of seed oil in cultivated P. ostii. This study selected five representative cultivation methods, open field cultivation, sunny slope cultivation, shady slope cultivation, understory intercropping cultivation, and high-altitude cultivation, and investigated the influence of cultivation method differences on the oil-use feature based on the three aspects of seed yield traits, oil yield, and fatty acid compositions. Six seed yield traits (fruit pod length, fruit pod width, fruit pod thickness, number of fruit pods per plant, 1000-grain weight, and seed yield per plant) and oil yield reached the maximum values of 7.75 cm, 6.99 cm, 1.57 cm, 11.33, 290.45 g, 85.8 g, and 30.41%, respectively, using the understory intercropping cultivation method. Fatty acid compositions were mainly identified as α-linolenic acid, linoleic acid, oleic acid, stearic acid, and palmitic acid, with significant content differences among different cultivation methods (P < 0.05). Functional component α-linolenic acid and total amounts of unsaturated fatty acids reached the maximum values of 46.85% and 65.23%, respectively, with high-altitude cultivation and understory intercropping cultivation. The seed yield traits, oil yield, and total amounts of unsaturated fatty acids were optimal with the understory intercropping cultivation method, whereas high-altitude cultivation was conducive to the accumulation of α-linolenic acid. Understory intercropping cultivation with appropriate altitude increases is recommended as a preponderant cultivation method for high-yield and high-quality seed oil harvesting for this crop.

Abstract Supercritical CO2 was used as solvent for the extraction of aucubin from the seeds of Eucommia ulmoides Oliv. The co-solvent composition was tested and extraction conditions were optimized. Results showed that the best co-solvent was a waterethanol mixture (1 + 3, v/v), and the highest yield was obtained when the extraction was performed under 26 MPa at extraction and separation temperatures of 55 and 30C for 120 min, using 6 mL co-solvent/g material at a CO2 flow rate of 20 L/h. In a comparison of the supercritical CO2 and Soxhlet extraction methods, the Soxhlet method needed 3 h to extract 10 g material, whereas the supercritical CO2 extraction technique needed only 2 h to extract 100 g material, thus showing a high extraction capability. The supercritical CO2 extraction produced a higher yield, with a lower cost for the extraction. Owing to the advantages of low extraction temperature, high yield, and ease of separating the product from the solvent, supercritical CO2 extraction is likely to be developed into an ideal technique for the extraction of aucubin, a compound with thermal instability, from the seeds of this plant.
