【摘要】 采用红外光谱阵列相关系数比对法对中国传统中药——丹参的产地与生长环境进行了鉴别研究。结果表明,对特定谱段范围内设置较高相关系数阈值进行比对能快速鉴别丹参产地;对R5—R7谱段范围内设置较低相关系数阈值的设置能对丹参进行生长环境分类识别。该方法对丹参的聚类识别具有快速、简便、准确的特点。更多还原

【Abstract】 Based on the fingerprint infrared spectrum database,array of correlation coefficient has been first applied to identify traditional Chinese medicine slviae miltiorrhizae Bge.from different producing areas and growing environments.The result showed that the setting of high correlation coefficient in particular ranges of spectrum could differentiate the producing area of Slviae,while the setting of low correlation coefficient threshold of R5 to R7 ranges could identify wild or cultivated samples.This approach seems to be not only a simple but also an accurate method for identifying the character of different Slviae.更多还原
