摘    要:采用红外光谱和气相色谱/质谱联用技术,研究了背刺毡蜡蚧Eriopeltis festucae(Fonsc.)(蚧总科Coccoidea,蚧科Coccidae)蜡泌物的化学成分。结果证明,该虫蜡泌物主要成分是一系列高分子的长链饱和烃、饱和与不饱和脂肪酸、脂肪醇和类酯,同时有少量的酮类、带有氧环和苯环的化合物。其碳原子数目在14-28之间,饱和烃为C21-、C22-、C24-、C28-(占28.47%),带氧环的长链烃C19-(占19.41%)。饱和酸是C16-(占50.09%)、C18-(占17.15%)、C24-(占19.24%)。醇是C25-烷醇和C22-烯醇。酯类是C27-辛酸甘油酯和C16-乙酸烯酯。

关 键 词:蚧虫  背刺毡蜡蚧  蜡泌物  化学成分  蚧科  长链饱和烃  脂肪酸  脂肪醇

Abstract:The chemical composition of waxes secreted by the scale insect Eriopeltis festucae (Fonsc.) was researched through the techniques of infrared absorption spectra (IR) and gas chromatography/mass spectrometry (GC/MS). The result indicates that the waxes are composed by a series of greater molecular compounds. They are long chain hydrocarbons, fatty acids, fatty alcohol and esters. Among of which are with oxy or phenyl cycles. The carbon atoms in the compounds rang 14~28. The saturated alkanes are major accounted by C 21 - , C 22 - , C 24 - , C 28 - straight chain hydrocarbon (28.47%), and C 19 - (19.41%) oxygen cycle. The saturated acids mainly consisted in C 16 - (50.09%),C 18 - (17.15%) and C 24 - acid (19.24%). The fatty alcohol are pentacosanol and docosenol. The esters are 13 Tertadecen l ol acetate and Glycerol tricaprylate.$$$$
Keywords:scale insect  Eriopeltis festucae  (Fonsc  )  waxes  chemical composition
