“…In an analytical mode and in combination with soft ionization mass spectrometry, this method gives excellent results, as has been repeatedly documented in our studies (Rezanka, 2002;Rezanka and Sigler, 2006). As mentioned above, the fatty acids from Ximenia oil have been identified and quantified by gas chromatography many times.…”

“…In previous papers (Rezanka, 2002;Rezanka and Sigler, 2006) we published a method suitable for enriching mixtures of natural fatty acids. This method is based on RP-HPLC, which could be used not only for enrichment of total fatty acids with VLCFAs but also for separation of individual compounds.…”

“…Based on our previous experience with semi-preparative RP-HPLC (Rezanka, 2002;Rezanka and Sigler, 2006) we have now used its preparative mode for the rapid enrichment of the VLCFA fraction with minimal losses. The presence of VLCFAs in Ximenia oil was demonstrated by a newly developed method, i.e.…”

“…For the same concentration of aqueous extract, 70% ethanol extract and the 100% ethanol extract (500 μg/mL) in the ABTS assay, the corresponding ABTS radical scavenging rates were 70.50%, 82.74% and 96.22%, respectively. This may be attributed to the fact that high concentration of fat‐soluble bioactive components were extracted (Rezanka and Sigler ; de Lucas et al . ) and those ingredients responsible for DPPH and ABTS scavenging activity were more easily dissolved in ethanol solution (Raghavendra et al .…”

“…For the same concentration of aqueous extract, 70% ethanol extract and the 100% ethanol extract (500 lg/mL) in the ABTS assay, the corresponding ABTS radical scavenging rates were 70.50%, 82.74% and 96.22%, respectively. This may be attributed to the fact that high concentration of fat-soluble bioactive components were extracted (Rezanka and Sigler 2006;de Lucas et al 2007) and those ingredients responsible for DPPH and ABTS scavenging activity were more easily dissolved in ethanol solution (Raghavendra et al 2013;Zhu et al 2014). From the view of the EC 50 value, capacity of these three extracts to the ABTS radical was higher than that of the DPPH radical, for example, the 100% ethanol extract showed the most potential DPPH and ABTS scavenging activity, with an EC 50 value of 102.022 lg/mL and 64.600 lg/mL, respectively, which may indicate that sugarcane mixed juice scum has both polar and nonpolar components and is more sensitive to the ABTS assay according to the mechanism of radical scavenging.…”

The scum is a semisolid by-product in canesugar mills where flotation technology is used for mixed juice clarification. To evaluate its potential bioactive properties, an aqueous extract, a 70% ethanol extract and a 100% ethanol extract from the scum were obtained and used for antioxidant activity assessment. Chemical assays of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2 0 -azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) diammonium salt (ABTS) were used to determine the total antioxidant activity, and a chemiluminescence assay was conducted to assess the hydroxyl (•OH) and superoxide anion (O 2•2 ) radicals' scavenging activity. Results showed that all extracts had high antioxidant activity, of which the 100% ethanol extract was more powerful in DPPH, ABTS and •OH assays. Potential antioxidants in ethanol extracts could be associated with sugarcane wax, polyphenols and flavonoids, while in the aqueous extract, it could be water-soluble vitamins and proteins which resulted in the highest (O 2•2 ) scavenging activity. This study suggested that the scum has potential bioactive application.

A review of waxes is provided, including classification, source, composition, production, testing, and applications. Waxes are generally classified according to source, such as natural waxes derived from animals or vegetables; mineral waxes derived from petroleum, coal, and peat; and synthetic waxes derived through polymerization of feed stocks, such as ethylene, methylene, and α‐olefins. The composition varies widely among the different classifications. Most of the natural waxes are mixtures with long‐chain alcohols, long‐chain carboxylic acids, and long‐chain esters as the major constituents. Waxes derived from coal and peat are similar, while the petroleum waxes consist almost exclusively of long‐chain hydrocarbons. Petroleum‐derived waxes are produced in massive quantities throughout the world. The synthetic waxes are generally low molecular weight polymers, with ethene polymers being the largest volume product. Since all waxes are fairly complex mixtures, physical properties are often used to describe the products. Uses vary from consumer products, such as chewing gum, cosmetics, and candles, to industrial applications, such as hot‐melt adhesives for carton sealing, flow modifier for plastic resins, and process additive for suspension polymerization.
