产品描述

Heptadecanoic acid methyl ester is an esterified form of heptadecanoic acid . It has been found in biodiesel produced by C. sorokiniana microalgae as well as in several types of animal fat biodiesel. Heptadecanoic acid methyl ester has been used as an internal standard for the quantification of fatty acid methyl esters in human plasma.

[Quantifiable method of polyunsaturated fatty acids in human plasma by optimized gas chromatography]

Wei Sheng Yan Jiu 2021 Nov;50(6):981-985.PMID:34949327DOI:10.19813/j.cnki.weishengyanjiu.2021.06.018.

Objective: To optimize the quantifiable method for determining polyunsaturated fatty acids in human plasma by gas chromatography(GC). Methods: Plasma was added with Heptadecanoic Acid methyl ester internal standard, and the total plasma lipids was extracted with methanol and n-hexane under the condition of ultrasonic water bath. The sulfuric acid methanol was used for methyl esterification. After centrifugation, the supernatant was filtered with a membrane and dried by nitrogen, and then re-dissolved by n-hexane. HP-88 GC column(30 m×0.25 mm, 0.2 μm) was used to separate linoleic acid(LA), α-linolenic acid(α-ALA), arachidonic acid(AA) and docosahexaenoic acid(DHA) with programmed temperature, and internal standard method was used to draw standard curve for quantitative analysis. Results: Ultrasonic water bath at 40 ℃ for 20 min could realize a higher total lipid extraction rate in a shorter time. The experimental concentration of four fatty acids range showed a good linear relation with the peak area ratio, correlation coefficient(r>0.995). The rate of recovery of four fatty acids were between 84.05%-101.23% with relative standard deviation(RSD) of 1.21%-6.77%, and the RSD of precision, within-day stability and day to day stability were 0.01%-0.04% and 0.02%-0.07%, respectively. No significant differences in the concentration of α-ALA, AA and DHA were observed between plasma and serum. The concentration(M(P25, P75)) of LA was higher in serum [93.38(79.18, 116.41) μg/mL]compared with plasma [72.12(50.93, 101.13) μg/mL], and the difference were significant(P<0.05). Conclusion: This method has a higher rate of total plasma lipids with shorter time, and the internal standard-standard curve method could eliminate the influence of the sample amount on the result. The determination of four polyunsaturated fatty acids was accurate, which could be used for the determination of plasma polyunsaturated fatty acids content in large sample populations.

Hollow fiber liquid-phase microextraction coupled with gas chromatography-flame ionization detection for the profiling of fatty acids in vegetable oils

J Chromatogr A 2010 Dec 24;1217(52):8073-8.PMID:21081239DOI:10.1016/j.chroma.2010.10.052.

The development of a two phase hollow fiber liquid-phase microextraction technique, followed by gas-chromatography-flame ionization detection (GC-FID) for the profiling of the fatty acids (FAs) (lauric, myristic, palmitic, stearic, palmitoleic, oleic, linoleic, linolenic and arachidic) in vegetable oils is described. Heptadecanoic Acid methyl ester was used as the internal standard. The FAs were transesterified to their corresponding methyl esters prior to the extraction. Extraction parameters such as type of extracting solvent, temperature, extraction time, stirring speed and salt addition were studied and optimized. Recommended conditions were extraction solvent, n-tridecane; extraction time, 35 min; extraction temperature, ambient; without addition of salt. Enrichment factors varying from 37 to 115 were achieved. Calibration curves for the nine FAs were well correlated (r(2)>0.994) within the range of 10-5000 μg L(-1). The limit of detection (signal:noise, 3) was 4.73-13.21 ng L(-1). The method was successfully applied to the profiling of the FAs in palm oils (crude, olein, kernel, and carotino cooking oil) and other vegetable oils (soybean, olive, coconut, rice bran and pumpkin). The encouraging enrichments achieved offer an interesting option for the profiling of the minor and major FAs in palm and other vegetable oils.
