In1829 the chemical in the willow tree that can relieve pain and fever was discovered to be salicin. 1829年,人们发现柳树中能止痛退烧的化学物质为水杨醇葡萄糖甙。
The name is derived from a for acetyl, spir from the spiraea plant ( a source of the ingredient salicin) and in, a common suffix for medicines at the time. 阿司匹林的名字由乙酰基的首写字母A与绣线菊类植物(水杨苷成分的来源)一词中的Spir组合而成,末尾加上了一个当时药物的常见后缀in。
The ancient Greeks, for example, treated pain with a tea made by boiling willow leaves and bark, a tea modern scientists now know contains salicin, a precursor of acetylsalicylic acid& aspirin. 例如,古希腊人用柳叶和柳树皮煮成的茶水来止痛。现代科学家已经了解到,这种茶里面含有水杨苷成分,就是乙酰水杨酸&阿司匹林的前身。
The enzyme activities were decreasing with time. The enzyme acts specially on salicin. 随时间推移,两类菌株的H+-ATP酶活性均逐渐降低,在酶的作用时间差别上有统计学意义(P<0.01)。
The vitro methods include autoagglutination test, calcium dependency test, pyrazinamidase test, salicin fermentation, esculin hydrolysis, Congo red colony test and virulence plasmid. 体外法包括自凝试验、依钙试验、吡嗪酰胺酶试验、水杨苷发酵、七叶苷水解、刚果红菌落试验和毒力质粒。
Jiang'an plum ( Prunus salicin Lindl.) fruits were treated with different chemicals before they were placed in small plastic film bags and stored at 3 ℃± 1 ℃. 江安李采后用不同的化学药剂处理,结合塑料薄膜袋小包装,在3℃±1℃条件下贮藏。
Determination of Salicin in Extract of Willow Bark by High Performance Liquid Chromatography 高效液相色谱法测定柳树皮提取物中的水杨甙
It was identified as Pasteurella multocida according to microscopy observation, culture characters and biochemical characters. But it was different to other Pasteurella multocida that the bacteria could utilize salicin, rhamnose and arabinose. 经显微镜观察、培养特性观察、生化特征鉴定,此菌为多杀性巴氏杆菌,但此菌与其他多杀性巴氏杆菌不同的是它能利用水杨素、鼠李糖、阿拉伯糖。
Making standard curve by salicin enzyme activity, we can get the formula of relative and absolute enzyme activity, then transform into absolute enzyme activity of glucose. 通过水杨苷法作葡萄糖标准曲线,能得到相对酶活与绝对酶活的换算公式,进而得到绝对酶活。
