Abstract

The intact C33-C52 diester wax esters of the preen gland of the shorebirds Limosa lapponica, Pluvialis squatarola, and Pluvialis fulva were determined, using synthesized standards, to comprise predominantly C12-C16 beta-hydroxy fatty acids esterified with a C8-C18 fatty acid at the beta-hydroxy position and with predominantly C12-C20 fatty alcohols esterified at the carboxyl group.

摘要

利用合成标准品，测定了滨鹬、灰斑鸻和金鸻的尾脂腺中完整的C33 - C52二酯蜡酯，结果表明其主要由β - 羟基位置被C8 - C18脂肪酸酯化且羧基位置主要被C12 - C20脂肪醇酯化的C12 - C16β - 羟基脂肪酸组成。
