三种木香的气相色谱法鉴别与系统聚类分析

Identification and clusteranalysis of Radix Inulae, Radix Vladimiriae and Radix Aucklandiae by GC

目的鉴别木香、川木香及土木香。方法采用气相色谱法,毛细管柱:HP5(0.32mm×0.25μm,30m);载气:N2(99.999%);检测器:氢火焰。结果在选定色谱条件下,建立了稳定可控的药材气相色谱图;应用系统聚类法可分为三类。结论应用气相色谱法与系统聚类法鉴别木香、川木香及土木香是可行的。

OBJECTIVE To identify Radix Inulae, Radix Vladimiriae and Radix Aucklandiae.METHODS Column: HP-5( 0.32 mm×0.25μm,30m); mobile phase: N_2(99.999%); detection: FID.RESULTS Using above optimum chromatography conditions, the GC chromatography of relative medicinal materials was established.CONCLUSION The GC chromatography can be used for identification of Radix Inulae, Radix Vladimiriae and Radix Aucklandiae.
