羊奶果种子脂肪酸组成和矿质元素分析

Fatty Acids and Mineral Elements of Seeds of Elaeagnus conferta Roxb.

摘要:

测定了羊奶果(Elaeagnus conferta Roxb.)种子脂肪酸组成以及矿质元素含量。结果表明：脂肪酸含量为1.98 %，主要是油酸(C₁₈﹕1)34.15 %、亚油酸(C₁₈﹕2)31.51 %、软脂酸(C₁₆﹕0)13.83 %、硬脂酸(C₁₈﹕0)2.88 %。饱和脂肪酸:单不饱和脂肪酸:多不饱和脂肪酸含量比为1:2.23:2.75。矿质元素K高达7 837.69 mg kg^-1，Fe为30.99 mg kg^-1、Zn为10.13 mg kg^-1，Na为259.5 mg kg^-1。

Abstract:

Fatty acids and mineral elements of the seeds of Elaeagnus conferta Roxb. were examined. The yield of seed oil was 1.98%. The main components were oleic acid (C₁₈﹕1, 34.15%), linoleic acid (C₁₈﹕2, 31.51%), palmitc acid (C₁₆﹕0, 13.83%) and stearic acid (C₁₈﹕0, 2.88%). The ratio of saturated fatty acids : mono-unsaturated fatty acids : poly-unsaturated fatty acids was 1:2.23:2.71. The contents of mineral elements were as follows, 7 837.69 mg kg^-1 for K, 30.99 mg kg^-1 for Fe, 10.13 mg kg^-1 for Zn and 259.5 mg kg^-1 for Na.
