不同取浆时间对蜂王浆产量和成分的影响

摘要

研究不同取浆时间（48 h和72 h ）对蜂王浆产量和成分的影响。以意大利蜜蜂为实验材料，利用免移虫蜂王浆生产技术生产蜂王浆，测定48 h和72 h取浆时单个王台中的王浆产量和单个幼虫重量以及10－HDA的相对含量、挥发性成分和脂溶性成分等指标。结果表明：72 h取浆时王台中王浆产量和幼虫重量都显著高于48 h，但两者10－HDA含量差异不显著；两者都含有21种相同挥发性成分和15种相同脂溶性成分，但48 h取的王浆含有更多的特有挥发性成分，而72 h取的王浆含有更丰富的特有脂溶性成分。%In order to study the effects of different harvesting times(48 h and 72 h)on the yield and com⁃position of royal jelly. The colony of Apis mellifera ligustica was used as the experimental material to produce royal jelly using the non⁃grafting larvae royal jelly production technique.In each experimental group,the yield of royal jelly in a single queen cell and the weight of a single larvae as well as the relative contents of 10 –HDA,volatile components and fat⁃soluble components in the royal jelly were investigated. The results showed that when royal jelly was harvested at 72 h the yield of royal jelly in a single queen cell and the weight of a sin⁃gle larvae were significantly higher than those when royal jelly was harvested at 48 h.Moreover,the royal jelly harvested at 72 h contained more specific fat⁃soluble components,while the royal jelly harvested at 48 h con⁃tained more unique volatile compositions,although they both contained the same 21 types of volatile composi⁃tions and 15 types of fat⁃soluble components, but the relative contents of 10 – HDA showed no significant difference between them.
