摘　　要：为了研究野菊花对机体热耐受能力的影响,选取1%,3%,5%和7%浓度的野菊花水提物(WE-FCI)喂养果蝇,进行热暴露试验和热适应试验。结果表明:在热暴露试验中,不同浓度的野菊花水提物均可显著延长雌性果蝇的半数致死时间(LT50)、平均存活时间(T)及最高存活时间(Tmax),当WE-FCI浓度≥3%时才能提高雄性果蝇的热耐受能力;在热适应试验中,不同浓度WE-FCI对果蝇热耐受指标的影响无明显规律,整体上3%WE-FCI能够稳定提高果蝇的LT50、T及Tmax。说明野菊花具有提高机体热耐受能力的作用,该结果为野菊花消暑饮料的研发提供了科学依据。In order to investigate the effect of water extract from Flos Chrysanthemi Indici （WE FCI） on the heat tolerance of organism, drosophila melanogaster was feed with 1%, 3%, 5%, 7% WE-FCI, respectively, to conduct heat exposure test and heat acclimatization test. The results showed： In heat exposure test, WE-FCI could sig- nificantly prolong the median lethal time （LT5o）, the average survival time （T）and the maximum survival time （Tmax） of female drosophila melanogaster, which were compared to HE-control group; When the concentration of WE-FCI was 3%, it would improve the heat tolerance of male drosophila melanogaster. Under heat acclima- tization test, different concentrations of WE FCI influencing the dro- sophila melanogaster＇s heat tolerance index had no obvious regula- tion; In the whole, 30/00 WE-FCI could stably improve the LTso, T and Tmax of drosophila melanogaster. It suggested that FCI can in crease the heat tolerance of drosophila melanogaster exposed to high temperature environment, which can provide scientific basis for the research and development of FCI heat-relieving drink.
