蜂胶的化学多样性及标准化存在的问题 总被引:3,自引:0,他引:3
蜂胶是西方蜜蜂从植物的树芽、树皮等部位采集的树脂粘液等再混合蜜蜂的舌腺、蜡腺等腺体分泌物,经蜜蜂加工而成的一种胶状物质。从远古时代。民间就把蜂胶作为一种药物来使用,直到今天在巴尔干半岛上的人们仍然用蜂胶治疗伤口、烧伤、烫伤、咽喉肿痛、胃溃疡等疾病。由于蜂胶在民问使用非常普遍,近30年来研究者对蜂胶的药理活性及化学成分进行了全面的研究。发现蜂胶具有广泛的药理活性:抗细菌、抗真菌、抗病毒、抗炎症、保肝、抗氧化、抗肿瘤等,而且蜂胶化学成分主要由蜜蜂采集的植物决定,因而在不同地区、不同气候条件下所采集的蜂胶化学成分相差很大。 相似文献

雄性蜂头部下唇腺分泌物在蜂王和雄性蜂交尾行为中发挥着重要作用。为探究雄性蜂下唇腺分泌物组成特性,本研究以青藏高原地区特有物种长翅熊蜂Bombus longipennis雄性蜂为材料,利用气相色谱-质谱联用和气相色谱技术对其下唇腺分泌物挥发性成分进行定性和定量分析。结果表明,长翅熊蜂雄性蜂下唇腺分泌物挥发性成分共28种,其中3,7,11-三甲基-6,10-十二碳二烯-1-醇为其主要成分,相对含量为38.45%。研究结果为深入探究熊蜂交尾行为的化学通讯机制奠定了基础,也为利用下唇腺分泌物进行熊蜂物种鉴定提供了依据。 相似文献

不同产地蜂胶的抗氧化活性 总被引:1,自引:0,他引:1
不同地区生产的蜂胶,由于其化学成分不同,因而抗氧化活性也不同。比较了产自阿根廷、澳大利亚、巴西、保加利亚、智利、匈牙利、新西兰、南非、泰国、乌克兰、乌拉圭、美国、乌兹别克斯坦以及中国(河北、湖北和浙江)的蜂胶乙醇提取液的抗氧化活性以及总酚酸类、黄酮类的含量,结果表明:产自阿根廷、澳大利亚、中国、匈牙利以及新西兰的蜂胶醇提取液具有很强的抗氧化活性,并且抗氧化活性与其总酚酸类及黄酮类含量相关,其中主要的抗氧化组分为堪菲醇和咖啡酸苯乙酯。 相似文献

本文综合整理了近年关于台湾产蜂胶的研究成果,台湾蜂胶被归类为"太平洋蜂胶",主要可以分成3类,其中以产于5~8月的TW-I台湾绿蜂胶最具生产利用价值。台湾绿蜂胶的化学组成与其它地区产蜂胶的化学组成不同,目前已分离出10种具活性的蜂胶素(propolins),它们属于prenylflavanones类的化合物,我们命名为蜂胶素A、B、C、D、E、F、G、H、I与J。其中蜂胶素A、B、E、H、I与J是新的化合物。在生物活性方面,我们的研究显示台湾绿蜂胶具有多种生物活性功能,包括抗癌、抗氧化与抗菌活性,非常值得进一步研究与利用。 相似文献

Shedding of porcine reproductive and respiratory syndrome virus in mammary gland secretions of sows.
E A Wagstrom C C Chang K J Yoon J J Zimmerman 《American journal of veterinary research》2001,62(12):1876-1880
OBJECTIVE: To document shedding of porcine reproductive and respiratory syndrome (PRRS) virus in mammary gland secretions of experimentally inoculated sows, to evaluate effects of vaccination during gestation on virus shedding during the subsequent lactation, and to evaluate shedding of PRRS virus in milk of sows in commercial herds. ANIMALS: 6 sows seronegative for PRRS virus were used for experiment 1, and 2 sows were retained for experiment 2. For experiment 3, 202 sows in commercial herds were used. PROCEDURE: In experiment 1, 2 sows were inoculated with PRRS virus, 2 sows were vaccinated with modified-live PRRS virus vaccine, and 2 sows served as control pigs. Mammary gland secretions were assayed for PRRS virus. In experiment 2, pregnant vaccinated sows from experiment 1 were vaccinated with another modified-live PRRS virus vaccine. Mammary gland secretions were assayed in the same manner as for experiment 1. For experiment 3, milk collected from 202 sows in commercial herds was assayed for PRRS virus. RESULTS: In experiment 1, PRRS virus was detected in mammary gland secretions of both vaccinated and 1 of 2 virus-inoculated sows. In experiment 2, virus was not detected in samples from either vaccinated sow. In experiment 3, all samples yielded negative results. CONCLUSIONS AND CLINICAL RELEVANCE: Na?ve sows inoculated late in gestation shed PRRS virus in mammary secretions. Previous vaccination appeared to prevent shedding during the subsequent lactation. Results for samples obtained from sows in commercial herds suggested that virus shedding in mammary gland secretions of such sows is uncommon. 相似文献

The European honey bee (Apis mellifera) has the unusual status of being an inherently wild species from which a natural foodstuff (honey) is derived by manipulating its behaviour to deposit this in man-made wooden frames. Bees also produce propolis and Royal Jelly which can be harvested but their most important effect is one not immediately obvious as an economic product: that of pollination. Bee diseases are predominantly infectious and parasitic conditions accentuated by the close confinement in which they congregate, either in man-made hives or in colonies in a natural cavity. Treatment or at least control of some of these conditions can be attempted. In some cases natural bee behavioural traits limit the effect of the disease while in others, such as the notifiable disease American foulbrood, destruction of the colony is the only method of control. The mite Varroa jacobsoni can be controlled by the synthetic pyrethroids flumethrin and tau-fluvalinate. The introduction of these products has heightened veterinary interest in this important invertebrate species. 相似文献
