Examples
- The ninhydrin reaction was negative , but when the preparation was hydrolyzed with 12n hc1 at 110 for 24h , it became positive
茚三酮反应呈阴性，但在110酸解后反应又呈阳性。 - This paper reviews recent advances in research and development of triketone herbicides , including discovery research and commercial compounds
摘要介绍了三酮类除草剂的研究和开发状况，包括它的研究开发历程、已商品化的品种。 - Colorless materials can be used if some means of detecting them is used ( electronic detection , radioactive labeling , or ninhydrin developer )
如果运用一些其他的检测方法（电子检测，放射性标记，茚三酮等）无色的物质也可以使用。 - The metabolite is soluble in water and insoluble in the organic solvent such as methanol , can be precipitated by acid , is positive with ninhydrin reaction and is considered as a kind of peptide
此物质溶于水，不溶于甲醇，可被酸沉淀，茚三酮反应为阳性，初步推断此活性物质为多肽类物质。 - New patents and structure - activity relationships are discussed , along with structural characteristics of the triketone derivatives and new ideas for design and synthesis
着重研究了关于此类化合物的专利申请情况，特别是2000年以后的研究开发趋势，探讨了三酮类结构特点、概述了构效关系的研究。
