Abstract
Euphorbiae Humifusae Herba (EHH) was provided with medicinal and edible uses, but frequently was adulterated with its closely related species. Hence, this study sought to identify EHH via an integrated approach comprising data from its morphological evaluation, HPLC analysis, comparative plastomes analysis and allele-specific PCR identification. First, the morphological characteristics of 8 subgenus Chamaesyce plants were summarized. Then, HPLC analysis showed that 18 batches of EHH were adulterated or unqualified. Furthermore, the plastomes of the 8 subg. Chamaesyce species were analyzed. Phylogenetic analysis revealed a sister relationship among the 8 subg. Chamaesyce species. The allele-specific PCR authentication was developed by the nucleotide polymorphisms (SNPs) and insertions or deletions (InDels) analysis. The results of allele-specific PCR showed that 27 batches of EHH were adulterated, indicating that the superior sensitivity of molecular authentication over the other methods used. This study provided a reference for rational use and phylogenetic research of EHH.
