毒理性
识别和使用:茉莉酮是一种淡黄色的粘稠液体(油)。它在精细茉莉花基和花香调的香水中有应用。人类暴露和毒性:茉莉酮在人类志愿者中没有引起皮肤致敏。动物研究:在10只兔子的急性皮肤毒性研究中,给予每只5克/千克的顺式-茉莉酮,并观察了14天。九只动物出现了严重的红斑,所有动物都观察到了中度的水肿。两只兔子发现了焦痂。茉莉酮在豚鼠中既不刺激也不致敏。在兔子眼睛刺激性研究中,最高剂量组显示出强烈的红斑、强烈的分泌物和水肿,在第6天完全消退。其余剂量显示出轻微到中度的红斑和分泌物,在第3天完全消退。茉莉酮在Ames平板掺入和预培养试验中,在添加和不添加代谢活化的情况下,浓度高达2500微克/平板时没有表现出致突变性。在试验中使用的鼠伤寒沙门氏菌菌株是TA98、TA100、TA102、TA1535和TA1537。然而,在中国仓鼠卵巢(CHO)细胞的细胞遗传学试验中,姐妹染色单体交换(SECs)的频率在33.3微摩尔浓度下显著增加,在最高测试剂量100和300微摩尔时也是如此。
IDENTIFICATION AND USE: Jasmone is a pale yellow, viscous liquid (oil). It is used in perfumery in fine jasmin bases and floral compositions. HUMAN EXPOSURE AND TOXICITY: Jasmone did not induce dermal sensitization in human volunteers. ANIMAL STUDIES: In an acute dermal toxicity study in 10 rabbits were give 5 g/kg cis-jasmone and observed for 14 days. Severe redness was seen in nine animals and moderate edema was observed in all animals. Eschar was found in two rabbits. Jasmone was not irritating or sensitizing in guinea pigs. In a rabbit eye irritation study, the highest dose group showed strong redness, strong secretion and edema, completely resolving by day 6. The remaining doses showed slight to moderate redness and secretion, completely resolving by day 3. Jasmone was not mutagenic in the Ames plate incorporation and pre-incubation assays with and without metabolic activation at concentrations up to 2500 ug/plate. The strains of Salmonella typhimurium used in the assays were TA98, TA100, TA102, TA1535 and TA1537. However, in a cytogenetic assay in Chinese hamster ovary (CHO) cells frequency of sister-chromatid exchanges (SECs) was significantly increased at concentrations of 33.3 uM and at 100 and 300 uM, the highest dose tested.
