目的:研究苦瓜皂苷对秀丽隐杆线虫寿命的影响及其与降脂作用的相关性。方法:结合油红O染色与甘油三酯生化试剂盒分析苦瓜皂苷(50、100、200μg/mL)对线虫脂肪沉积的作用;通过测定线虫体长、体宽、运动能力以及寿命评估苦瓜皂苷对线虫基础生理指标的影响;采用实时荧光定量聚合酶链式反应技术检测脂代谢相关基因的mRNA表达水平;利用脂代谢相关基因缺失的线虫突变株,通过系统寿命评估,考察苦瓜皂苷调控线虫寿命与脂代谢的相关性。结果:100、200μg/mL苦瓜皂苷在不改变虫体大小、运动能力等基础生理指标条件下,能够显著降低线虫甘油三酯相对含量(P0.05)。结论:苦瓜皂苷延长线虫自然寿命的作用与其降低脂肪沉积的功效密切相关,其机制主要是抑制了脂肪酸合成途径中脱饱和酶fat-6和fat-7的基因表达。

为了探讨中国与日本不同品牌抹茶中氨基酸含量的差异性,采用OPA-FMOC柱前衍生化高效液相色谱(HPLC)法测定了16种贵州抹茶及6种日本抹茶中游离氨基酸和酸水解氨基酸的组成及含量;通过SPSS Statistics 19和Origin 8.5软件进行数据处理并制作指纹图谱,采用组间连接法进行了聚类分析。结果表明,贵州抹茶的游离氨基酸总含量在0.60%~2.58%,水解氨基酸总量在20.31%~25.75%,整体含量较日本抹茶偏低,个别品种接近日本抹茶,但茶氨酸的相对含量明显高于日本抹茶。不同来源的抹茶,其呈味氨基酸的含量也有明显不同。说明游离氨基酸和酸水解氨基酸指纹图谱可以作为抹茶特征识别的依据之一,并为抹茶原料选择和加工工艺优化提供重要理论依据和指导。

通过对江苏地区中华绒螯蟹重金属铅残留进行调查,评估食用此地中华绒螯蟹的健康风险。于2018—2020年9—10月,在江苏地区采集中华绒螯蟹样本424份,用电感耦合等离子体质谱法对样品中的重金属铅含量进行检测。结果表明,江苏地区中华绒螯蟹体内重金属铅含量范围在ND~0.547 mg/kg,平均值为0.025 0 mg/kg,99.5%满足国家相关标准的限量要求。单因子污染指数分析显示,99.5%的样品处于未污染或轻度污染水平。从采集区域的比较结果可以看出,铅含量:苏北地区<苏中地区<苏南地区。苏中和苏南地区没有显著性差异,而苏北地区与二者存在显著性差异。人群膳食风险评估表明,正常消费水平下,靶标危害系数值均远小于1,中华绒螯蟹重金属铅对人体健康造成的影响不明显。试验可为水产品质量安全评估及中华绒螯蟹的合理食用提供参考依据。
