摘要:

对新鲜蜂王幼虫中脂类物质进行提取及柱层析分离,分析各分离组分脂肪酸组成和其他脂溶性活性化合物的组成和含量。结果表明:蜂王幼虫脂类物质中含有74.4%的甘油三酯,其脂肪酸以棕榈酸(43.16%)和油酸(40.70%)为主,其他中性脂和磷脂中含有较高含量的癸酸。同时,蜂王幼虫中甾醇组成为24-亚甲基胆甾醇57.67%、菜油甾醇4.76%、β-谷甾醇16.56%,Δ5-燕麦甾醇19.45%以及环阿屯醇1.56%。此外,蜂王幼虫含有丰富的辅酶Q10和磷脂类化合物,其中脑磷脂含量为(1299.65±50.12)mg/100g(以油脂计)。

Abstract:

Lipids from fresh queen bee larvae were extracted and separated by column chromatography. A comprehensive
analysis of the chemical composition of fatty acids and other lipophilic compounds was carried out. The results showed that
the queen bee larvae lipids were composed of 74.4% triglyceride with palmitic acid (43.16%) and oleic acid (40.70%) as
dominant fatty acids. Other neutral lipids and phospholipids contained a high amount of capric acid. In addition, queen bee
larvae also contained various types of sterol compounds such as 24-methylene cholesterol (57.67%), campesterol (4.76%),
β-sitosterol (16.56%), Δ5-avenasterol (19.45%) and cycloartenol (1.56%). Moreover, queen bee larvae comprised rich
coenzyme Q10 and phospholipids, in which the phosphatidyl ethanolamine content was (1299.65 ± 50.12) mg /100 g lipid.
