    甲基乙二醛(MGO)被认为是负责Leptospermum种的抗菌活性的重要成分之一。(麦卢卡)蜂蜜。虽然许多研究已经证明了MGO在体外的剂量依赖性抗菌活性,从治疗的角度来看,确认其从麦卢卡蜂蜜和麦卢卡蜂蜜配方中的释放也很重要。这项研究是首次使用Franz扩散池和高效液相色谱(HPLC)分析报告含有麦卢卡蜂蜜的五种商业产品中MGO的释放曲线。在12小时内监测MGO的释放,以MGO含量的释放百分比表示,发现人造蜂蜜基质和NZManuka蜂蜜的释放率为99.49%和98.05%。分别。对于所研究的配方,在12小时的研究期间,MGO释放时间依赖性百分比在85%至97.18%之间。
    Methylglyoxal (MGO) is considered to be one of the vital components responsible for the anti-bacterial activity of Leptospermum spp. (Manuka) honey. While many studies have demonstrated a dose-dependent antibacterial activity for MGO in vitro, from a therapeutic viewpoint, it is also important to confirm its release from Manuka honey and also from Manuka honey-based formulations. This study is the first to report on the release profile of MGO from five commercial products containing Manuka honey using a Franz diffusion cell and High-Performance Liquid Chromatography (HPLC) analysis. The release of MGO expressed as percentage release of MGO content at baseline was monitored over a 12 h period and found to be 99.49 and 98.05% from an artificial honey matrix and NZ Manuka honey, respectively. For the investigated formulations, a time-dependent % MGO release between 85% and 97.18% was noted over the 12 h study period.

    亲爱的,一种天然的甜味和粘性物质,主要由蜜蜂(Apismellifera)从花蜜中产生。蜂蜜发挥了过多的生物和药理活性,即,抗氧化剂,抗菌和抗炎活性,因为存在各种各样的生物活性化合物。抗菌活性是被报导最多的生物学性质之一,许多研究表明蜂蜜对临床上重要的病原体具有活性。因此,除了蜂蜜作为一种常见的食品和调味剂的广泛利用,蜂蜜是一种有吸引力的天然抗菌剂。然而,使用纯蜂蜜进行治疗会带来一些问题,例如,其粘性可能会阻碍其对消费者和医疗保健专业人员的吸引力,由于蜂蜜的流动性和渗漏,在足够的时间范围内维持足够的治疗浓度可能具有挑战性。它促使研究人员将蜂蜜整合到不同的配方中,例如,水凝胶,敷料,软膏,糊剂和锭剂。应当科学地确定这些制剂的抗菌活性以强调有效性的要求。一些研究人员已经努力调整椎间盘载体和悬浮液测试,以评估局部产品的抗菌活性(例如,银基伤口敷料)。然而,目前还没有确定和验证的方法来确定基于天然产品的制剂的体外抗菌潜力,包括那些含有蜂蜜作为有效原则。在简要讨论有助于其抗菌活性的参数的背景下,这篇综述概述了目前用于研究纯蜂蜜抗菌活性的方法,并讨论了它们在蜂蜜制剂中应用的局限性。
    Honey, a naturally sweet and viscous substance is mainly produced by honeybees (Apis mellifera) from flower nectar. Honey exerts a plethora of biological and pharmacological activities, namely, antioxidant, antimicrobial and anti-inflammatory activity, because of the presence of an extensive variety of bioactive compounds. The antibacterial activity is one of the most reported biological properties, with many studies demonstrating that honey is active against clinically important pathogens. As a result, beside honey\'s widespread utilization as a common food and flavouring agent, honey is an attractive natural antimicrobial agent. However, the use of neat honey for therapeutic purposes poses some problems, for instance, its stickiness may hamper its appeal to consumers and health care professionals, and the maintenance of an adequate therapeutic concentration over a sufficient timeframe may be challenging due to honey liquidity and leakage. It has motivated researchers to integrate honey into diverse formulations, for example, hydrogels, dressings, ointments, pastes and lozenges. The antibacterial activity of these formulations should be scientifically determined to underscore claims of effectiveness. Some researchers have made efforts to adapt the disc carrier and suspension test to assess the antimicrobial activity of topical products (e.g., silver-based wound dressings). However, there is currently no established and validated method for determining the in vitro antimicrobial potential of natural product-based formulations, including those containing honey as the active principle. Against the backdrop of a brief discussion of the parameters that contribute to its antibacterial activity, this review provides an outline of the methods currently used for investigating the antibacterial activity of neat honey and discusses their limitations for application to honey-based formulations.
