摘要[目的]研究五谷蟲油脂抗菌活性。[方法]用8種不同類型配比的飼料養(yǎng)殖得到不同五谷蟲并烘干得到其干體,然后用索氏提取法分別提取得到不同種類五谷蟲油脂,并用紙片擴散法對這8種油進(jìn)行抗菌活性研究。[結(jié)果]用餐廚熟食飼養(yǎng)蠅蛆不僅成本低,且最終得到的油脂具有較好的抗菌作用,其對大腸桿菌有抑菌效果;而其余的油對大腸桿菌、枯草桿菌及金黃色葡萄球菌均無明顯抑菌效果。[結(jié)論]用餐廚熟食飼養(yǎng)的五谷蟲提取得到的油脂對大腸桿菌具有抑菌效果,從而為五谷蟲的研究利用展示了新的方向。

Abstract[Objective] The research aimed to study the antibacterial activity of traditional Chinese medicine Wuguchong grease.[Method]Different kinds of Wuguchong were obtained and dried by 8 different kinds of different kinds of feed,different kinds of grease were extracted by soxhlet extraction, and the antibacterial activity of the eight kinds of grease was studied by disk diffusion method.[Result]The feeding of the cooked food was not only low cost, but also the final grease had good antibacterial effect, it had bacteriostatic effect on Escherichia coli, and the other grease had no obvious antibacterial effect to Escherichia coli, Bacillus subtilis and Staphylococcus aureus.[Conclusion]The grease which extracted from Wuguchong fed with kitchen waste had inhibitory effect on Escherichia coli.Thus, the research and utilization of Wuguchong showed a new direction.

在中藥行業(yè),藥用昆蟲范疇內(nèi),昆蟲雙翅目大頭金蠅(Chrysomya megacephala,又名大頭麗蠅、東方廁蠅)及其近緣昆蟲(如家蠅Musca domestica)的干燥幼蟲(蠅蛆)是一味傳統(tǒng)中藥,名曰“五谷蟲”,又名水仙子、羅仙子,俗名“蛆”[1]。大頭金蠅屬全變態(tài)昆蟲,包括卵、幼蟲、蛹和成蟲4個發(fā)育階段[2],各個時期的形態(tài)各不相同[3]。《本草綱目》和《本草求源》表明,其具有清熱解毒、消積滯的功能,干燥后研磨,可供搽敷外用,能治療臁瘡、唇疔病癥[4]。蠅蛆的養(yǎng)殖成本低,飼養(yǎng)操作方便,飼養(yǎng)場地要求相對較低,當(dāng)溫度及相對濕度在適宜的條件下,其幼蟲的繁殖可以持續(xù)1年[5],它的生存適應(yīng)能力強,不受季節(jié)影響,從而被國際上列為新型蛋白質(zhì)源昆蟲之首[6]。大頭金蠅因其巨大的營養(yǎng)價值、藥用價值和商用價值,在國內(nèi)外都具有廣闊的市場[7]。……
