The purpose of this study was to examine the bovine rumen liquor wax esters and compare them with those of the dietary white clover leaf and stem tissues (Body, D.R. (1974) Phytochemistry 13, 1527-1530). The major fatty acid composition of the total bovine rumen liquor wax esters was made up of saturated fatty acids (62.1%) including palmitic (20.4%), stearic (16.2%) and other acids over the n-C19-n-C30 range (20.5%). However, 13.2% phytanic acid was also present. Of the two major fatty alcohol components, dihydrophytol (33.4%) and triacontanol (20.2%) were the principal contributors. Approximately 30% of the total intact rumen liquor wax esters was a series of dihydrophytyl wax esters. These represented 0.6% of the total rumen liquor lipid extract. Individually they were comprised of dihydrophytyl palmitate (0.05%), dihydrophytyl phytanate (0.10%) and dihydrophytyl n-C18 fatty acids (0.45%). The appearance of saturated isoprenoid moieties was the most striking difference between the composition of rumen liquor and dietary white clover wax esters.
本研究的目的是检测牛瘤胃液蜡酯,并将其与日粮白三叶草叶片和茎组织中的蜡酯进行比较(博迪,D.R.(1974年)《植物化学》13卷,第1527 - 1530页)。牛瘤胃液总蜡酯的主要脂肪酸组成由饱和脂肪酸(62.1%)构成,包括棕榈酸(20.4%)、硬脂酸(16.2%)以及碳数在C19 - C30范围内的其他酸(20.5%)。然而,也存在13.2%的植烷酸。在两种主要脂肪醇成分中,二氢植醇(33.4%)和三十烷醇(20.2%)是主要成分。瘤胃液中完整蜡酯总量的约30%是一系列二氢植基蜡酯。这些占瘤胃液脂质提取物总量的0.6%。它们分别由二氢植基棕榈酸酯(0.05%)、二氢植基植烷酸酯(0.10%)和二氢植基C18脂肪酸(0.45%)组成。饱和类异戊二烯部分的出现是瘤胃液和日粮白三叶草蜡酯组成之间最显著的差异。
