摘  要：
以广藿香(4种栽培类型)和藿香为材料,建立广藿香和藿香的X射线衍射图谱。结果表明,4种栽培类型广藿香的2θ余弦夹角值具有一定的相似性,均大于0.6;而藿香的2θ余弦夹角值为0.325,两者之间存在较大差异,建议以2θ余弦夹角值0.600作为参考标准,区分广藿香和藿香药材。广藿香和藿香特征峰强度不同,5个样品分为3类,广州石牌广藿香为Ⅰ类,在约7.5 nm处出现一个较为尖锐、强度较大的衍射峰;湛江广藿香、海南广藿香和肇庆广藿香为Ⅱ类,均在约4.0 nm处出现一个衍射特征峰;藿香归为Ⅲ类。粉末X射线衍射图谱法可用于广藿香和藿香的鉴定与分析,相似度的计算结果可用于该药材的质量评价,为广藿香和藿香药材的有效区分提供了科学的新方法。

摘  要：
Four cultivars of Pogostemon cablin,and Agastache rugosa were collected as samples to establish their X-ray powder diffraction fingerprint patterns for analysis.The analysis showed that the 2θ cosine values of 4 cultivars of P.cablin were similar(more than 0.6) while the 2θ cosine values of A.rugosa was 0.325,indicating a big difference between P.cablin and A.rugosa in the 2θ cosine value.It is suggested that the 2θ cosine value of 0.6 be used as the reference standard to distinguish between P.cablin and A.rugosa.P.cablin and A.rugosa were different in the intensity of characteristic peaks,and the 5 samples were divided into 3 categories.P.cablin 'Paixiang' had a sharp,higher diffraction peak intensity at 7.5 nm and was listed in Category I;P.cablin 'Zhanxiang','Zhaoxiang' and 'Nanxiang' were grouped into Category Ⅱ because of a sharp,higher diffraction peak intensity at 4.0 nm;A.rugosa was listed in Category Ⅲ.X-ray powder diffraction fingerprint pattern can be used for identification and analysis of P.cablin,and the results of similarity calculation can be used for quality evaluation.This provides a new scientific method for effective identification of P.cablin and A.rugosa.
