实验步骤: A solution of 2-hydroxy-3-octanoyloxypropyl octanoate (5.0 g.) in ether (30 ml.) was stirred with triethylamine (2.04 ml.) and glutaric anhydride (1.66 g.) for 3.5 hours. Further glutaric anhydride (0.8 g.) was then added together with triethylamine (1.0 ml.). This mixture was heated under reflux until no further starting octanoate could be detected by thin layer chromatography (silica: methylene chloride). The cooled reaction mixture was washed with 1M hydrochloric acid (2×20 ml.), then with water (2×20 ml.), dried (MgSO4) and evaporated to give 2-octanoyloxy-1-(octanoyloxymethyl)ethyl hydrogen glutarate as an oil (6.62 g.); NMR (CDCl3): 0.9 (6H, t, CH3), 1.1-2.1 (22H, m, CH2), 2.4 (8H, m, CH2CO), 4.0-4.4 (4H,m, CH2O), 5.1-5.4 (1H, br.t, CHO), 9.6 (1H, br.s, CO2H)ppm. Mass spectrum (major diagnostic peaks based on M=458, using chemical ionisation techniques): m/e 476 (M+NH4), 360 (M +NH4 --HO2C.(CH2)3.CO2H) This mixture was heated under reflux until The cooled reaction mixture was washed with 1M hydrochloric acid (2×20 ml.) with water (2×20 ml.), dried (MgSO4) evaporated

实验步骤: Dehesh et al. (1996, Plant J. 9(2):167-172) describe the expression of a FATB cDNA (Ch FATB2) from the Mexican shrub Cuphea hookeriana, which accumulates up to 75 mol % caprylate (C8:0) and caprate (C10:0) in its seed oil, in seeds of transgenic canola, which normally does not accumulate these fatty acids, resulting in the accumulation of caprylate (C8:0), caprate (C10:0) and laurate (C12:0) up to 11, 27 and 2 mol %, respectively.

实验步骤: One gram of sodium octanoate and one gram of levofloxacin were dissolved in 100 ml water. The pH was slowly adjusted to 6.0 by the addition of 1 M HCl. As the pH decreased, levofloxacin became protonated formed an insoluble HIP with the negatively charged octanoate. The precipitate was gathered by filtration to remove excess levofloxacin, dissolved sodium octanoate/octanoic acid, and salt. The sample was lyophilized overnight.
