Abstract
Defensive droplets from glandular hairs of the pupa of the Mexican bean beetle, Epilachna varivestis, contain a group of structurally novel alkaloids, the azamacrolides. The major constituent of this secretion, epilachnene, is shown to be (5Z)-11-propyl-12-azacyclotetradec-5-en-14-olide. The secretion also contains an epilachnadiene and trace amounts of three closely related components.
摘要
墨西哥豆瓢虫（Epilachna varivestis）蛹的腺毛分泌的防御性液滴中含有一组结构新颖的生物碱——氮杂大环内酯。这种分泌物的主要成分表毛菌素被证明是(5Z)-11-丙基-12-氮杂环十四碳-5-烯-14-内酯。该分泌物还含有一种表毛菌素二烯以及痕量的三种密切相关的成分。
