CVLP-A, CVLP-B, CVLP-C and CVLP-D, crude polysaccharides extracted from the leaves of C. violaceum collected from Chengdu, Langzhong, Bazhong and Guangyuan, respectively. Values represent mean ± standard deviation, and superscripts a–d differ significantly (p < 0.05) among CVLPs collected from different regions. Statistical significances were determined by A.N.O.V.A. and Duncan’s test.
