摘要
目的 研究比较各地广藿香的指纹图谱 ,并考察了裂解温度、裂解时间对指纹图谱的影响。方法 采用裂解色谱法 (PGC)测定 ,模糊聚类法分析。结果 不同产地样品的指纹图谱既有相似性 ,也有特征性 ,谱图的重现性好 ,其 RSD均≤ 2 .75 %。结论 此方法具有快速、简便、准确等特点 ,裂解温度。
Object To study comparatively the fingerprint of Pogostemon cablin (Blanco) Benth. in different producing area and investigate the effect of pyrolysis temperature and pyrolysis time on the fingerprint Methods Pyrolysis gas chromatography (PGC) and fuzzy cluster analysis were used Results Both similarity and charecteristics were found in the fingerprint of P. cablin in different producing area. The methodological evalulation showed that this method had a good reproducibility, RSD≤2.75% Conclusion This method is simple, rapid and accurate. It is suitable for the quality control of the Chinese materia medica with the important role of pyrolysis temperature and pyrolysis time
