Melissyl alcohol

The wax that bees make is a complicated mixture of many compounds, but about 70 percent of it is the wax made from palmitic acid, a fatty acid, and the long-chain alcohol triacontanol (melissyl alcohol). [Pg.62]

The concentration of fats and related substances in molasses is low analytical values depend on the extracting solvent.126 These tenaciously retained materials can be removed by fractionation of blackstrap on fuller s earth clay.70 Chromatography on a calcium silicate of the fat fraction of Cuban molasses led to the isolation of melissyl alcohol, a phytosterol fraction, chlorophyll a and a fat fraction containing a glyceride of linoleic acid.70 Stigmasterol and syringic acid are reported as ether-extractable constituents of molasses.127... [Pg.311]

Found in camauba wax, melissyl cerotate is an ester formed from melissyl alcohol and cerotic acid. [Pg.340]

Tiiacontanol (melissyl alcohol, myricyl alcohol). H3C-(CH2)28-CH20H, C30H62O, Mr 438.82, mp. 86.5 °C, soluble in toluene, insoluble in water. T. is a component of many plant waxes and occurs as the palmitate in bees wax. Triacontanal (C30H60O, Mr 436.80) has also been isolated from plant waxes. T. acts as a plant... [Pg.660]

The nature of the non-acid fraction of the wax is of interest.75 Some glycerol is present but the main alcohols are the higher-carbon mono-hydric alcohols, ceryl (n-C26H6i—CH2OH, isolated from Louisiana wax) and melissyl (isolated from Cuban molasses70). The latter is probably a... [Pg.300]

Waxes are complex mixtures of nonpolar lipids. They are protective coatings on leaves, stems, and fruits of plants and the skin and fur of animals. Esters composed of long-chain fatty acids and long-chain alcohols are prominent constituents of most waxes. Well-known examples of waxes include camauba wax, produced by the leaves of the Brazilian wax palm, and beeswax. The predominant constituent of camauba wax is the wax ester melissyl cerotate (Figure 11.5). Triacontyl hexadecanoate is one of several important wax esters in beeswax. Waxes also contain hydrocarbons, alcohols, fatty acids, aldehydes, and sterols (steroid alcohols). [Pg.340]

Hentriacontanol. H3C-(CH2)29-CH20H, CjiH O, Mr 452.84, mp. 87 °C. H. is a component of various plant waxes. In older literature l-triacontanol (melissyl or myricyl alcohol) is often wrongly named as H. The same holds for hentriacontanoic acid. [Pg.287]
