Fig. 4.3. High performance liquid chromatography (HPLC) of the monosaccharides obtained from a partially purified preparation of microbubble glycopeptide surfactant from forest soil. Following hydrolysis (in 2 N HC1 for 6 hr at 100°C) and filtration, the carbohydrate mixture was charged on a Bio-Rad HPX-87 cation exchange column. For comparison, part A shows the chromatogram (using the same HPLC column) of a standard solution, which contained 4 pg of each of three different monosaccharides (i.e., the last three peaks shown are glucose, xylose and fiicose, in the order of increasing retention times). Part B shows the chromatogram obtained from hydrolysis of the partially purified (see text) microbubble surfactant (approximately 30 pg). All other experimental conditions were identical in the two cases, i.e., water eluent, 0.5 ml/min flow rate, 85°C, refractive index detector attenuation -2x. (Taken from ref. 322.)... Fig. 4.3.

Absolute Difference Between Found and Theoretical Equivalent Carbon Number (ECN) 42 (Trilinolein) Values. The triglyceride composition of the oil is determined by high-performance liquid chromatography (HPLC) (74). (A chromatogram of an olive oil sample (ECN 42, 0.8%) is shown in Figure 10.) The theoretical triglyceride composition is calculated with a Lotus 123 program provided by the lOOC. The maximum difference of theoretical ECN 42 vs. ECN 42 found is calculated. (ECN = CN-2u, where CN is the carbon number and n is the number of double bonds.) The maximum difference between the real and theoretical ECN content... [Pg.961]
