本文应用顶空固相微萃取气相色谱-质谱联用技术，对威氏海链藻 Thalassiosira weissflogii 、小新月菱形藻 Nitzschia closterium 、角毛藻Chaetoceros calcitrons 3种硅藻的挥发性成分进行分析。结果表明，在3种硅藻的培养过程中，其挥发性成分除了壬醛及醇类呈现先增后降的趋势外，大多数不饱和醛类的含量在不断增加，烷烯烃类物质在不断减少，而乙酸乙酯、2-甲基-2-丙酸甲酯这类酯类化合物在角毛藻衰败期会显著富集。通过对代表性饵料硅藻的挥发性成分进行研究，可为海水养殖过程中微藻投喂种类、投喂时机的选择提供理论依据，并为海洋硅藻的进一步开发奠定基础。

The volatile components in marine diatoms Thalassiosira weissflogii ,Nitzschia closterium and Chaetoc-eros calcitrons were analyzed by head space solid-phase micro-extraction and gas chromatography-mass spectrome-try.The differences of volatile components among three diatoms at different growth stages were studied by SIM-CA-P software.The results showed that the content of most unsaturated aldehydes increased through the entire culture stages of three diatoms except for a saturated aldehyde,Nonanal,whose content first increased and then de-creased.The content of Alkanes continued to decline.Alcohols also increased first and then decreased.Esters in-cluding acetic acid ethyl ester and 2-methyl-2-Propenoic acid methyl ester were significantly enriched in the decline phase of C.calcitrons.According to the present study on volatile components of these diatoms,we can provide im-portant reference not only for choosing microalgae species and feeding period in marine aquaculture,but also for studying the reason of odor formation and further development and utilization of marine diatom.
