Fig. 2From: A multivariate analysis on the comparison of raw notoginseng (Sanqi) and its granule products by thin-layer chromatography and ultra-performance liquid chromatographyHCA dendrograms of Sanqi extracts analysed by (a) TLC and (b) UPLC. a HCA dendrograms for the TLC results divided the raw herb and granule extracts into two main clusters, with raw herb samples R1 to R4 classified into one cluster (Cluster 1), whereas R5 and R6 were grouped with the granules (Cluster 2). b The HCA for UPLC grouped granule samples G7 and G12 with the raw herb cluster (Group 1), with the rest of the granules in Group 2Back to article page
