Abstract

Plants are the major source of natural flavour ingredients reported for their wide applications in food and pharmaceuticals, oral care and wellness products, etc. We have investigated the water-soluble fractions (WSF) of basil tetraploid (O. basilicum L.) for their toxicity and biological potential against Salmonella Typhimurium, a pathogen causing around one million cases of illnesses in the United States every year. The WSF obtained using a Clevenger-type apparatus was further divided into two equal parts, one each for in-vivo toxicity evaluation and quality assessments, respectively. The proportions of major phenylpropanoid identified as meta-eugenol in the WSF were found in the range of 42.8-57.9%, which was substantially in higher proportion as compared to essential oil (20.9-23.0%). Based on sub-acute oral toxicity data, WSF has not shown any adverse effect with levels as high as 500 µL/25g body weight in Swiss albino mice. Besides, the WSF also exhibited a maximum reduction in bacterial load in mice infected with Salmonella Typhimurium in a dose-dependent manner. We have shown the biological potential of basil water-soluble fraction as an effective bacterial load-suppressing agent for the prevention of Salmonella infections in animal model.

揭示罗勒(Ocimum basilicum L.)的水溶性成分与其在小鼠模型中的毒性和抗伤寒活性的关系
据报道,植物是天然香料成分的主要来源,可广泛应用于食品、药品、口腔护理和保健产品等领域。我们研究了罗勒四倍体(O. basilicum L.)的水溶性馏分(WSF)对伤寒沙门氏菌的毒性和生物潜力。使用 Clevenger 型仪器获得的 WSF 被进一步分成两等份,每份分别用于体内毒性评估和质量评估。经鉴定,WSF 中的主要苯丙酮类化合物为偏丁香酚,所占比例为 42.8%-57.9%,与精油(20.9%-23.0%)相比,比例要高得多。根据亚急性口服毒性数据,WSF 在瑞士白化小鼠体内的浓度高达 500 µL/25g 体重时也未显示出任何不良影响。此外,WSF 还能以剂量依赖的方式最大程度地减少小鼠感染伤寒沙门氏菌后的细菌量。我们证明了罗勒水溶性成分作为一种有效的细菌负荷抑制剂,在动物模型中预防沙门氏菌感染的生物潜力。
