Abstract

The sorbic acid containing triglycerides found in various aphid species have been fractionated by high pressure liquid chromatography. Mass spectral analysis afforded identification of three isolates as 2-trans, trans-sorbo-1, 3 dimyristin; 2-trans, trans-sorbo-1,3 myristopalmitin; and 2-trans, trans-sorbo-1,3 dipalmitin. No evidence of asymmetry was found by circular dichroism. The composition and proportions of these triglycerides was found to be species variable.

摘要

已通过高压液相色谱法对在各种蚜虫物种中发现的含山梨酸甘油三酯进行了分离。质谱分析鉴定出三种分离物为2-反式，反式-山梨醇-1,3-二肉豆蔻酸酯；2-反式，反式-山梨醇-1,3-肉豆蔻棕榈酸酯；和2-反式，反式-山梨醇-1,3-二棕榈酸酯。圆二色性未发现不对称的证据。发现这些甘油三酯的组成和比例因物种而异。
