化学指纹图谱,chemical fingerprint
1)chemical fingerprint化学指纹图谱
1.For determining similarity ofchemical fingerprint, similarity measures were presented.提出化学指纹图谱相似性测度概念 ,并以峰数弹性、峰比例同态性和峰面积同态性为评价指标 ,用于多角度评价化学指纹图谱相似性测度优劣 ,根据这些评价指标 ,用计算机仿真方法研究比较了 6种相似性测度 ,结果表明夹角余弦测度用于度量指纹图谱间谱峰比例的波动较适宜 ,峰匹配测度可较灵敏地检测小峰个数波动 ,而欧氏距离测度则具有较好的综合评价能力 。
2.The application of thechemical fingerprint,biological biometric fingerprint and metabolic fingerprint in the quality control of traditional Chinese medicine research is reviewed in this paper.本文综述了化学指纹图谱、生物指纹图谱及代谢指纹图谱在中药质量控制研究中的应用。
3.Thechemical fingerprints of three groups of tea samples(Dianqing,Qingbing and Puer tea Shubing),were implemented based on analysis of tea polyphenols,caffeine and flavonoids content in teas defermined by HPLC.利用针对茶多酚类、咖啡碱及黄酮(苷)类物质含量变化的两个HPLC色谱数据的多元信息融合,制作了滇青(晒青毛茶)、青饼和普洱茶(熟饼)3组茶样的化学指纹图谱,并用欧氏距离、相似性分析、聚类分析和主成分分析等方法进行判别分析,结果发现,无论是生化组成、化学指纹图谱模式谱、聚类分析,还是主成分分析结果,青饼都与普洱茶(熟饼)有明显差异,而与晒青毛茶相似,说明1～2 a陈以内的青饼在化学成分上与普洱茶(熟饼)有着本质上的差异,而与晒青毛茶有很高的相似度,本质上还是属于绿茶。
