A nucleotide signature for the identification of Pinelliae Rhizoma (Banxia) and its products.

ABSTRACT:

Background

Ensuring the authenticity of raw materials is a key step prior to producing Chinese patent medicines. Pinellia ternata (Thunb.) Breit. is the botanical origin of Pinelliae Rhizoma (Banxia), a traditional Chinese medicine used to treat cough, insomnia, nausea, inflammation, epilepsy, and so on. Unfortunately, authentic Pinelliae Rhizoma is often adulterated by morphologically indistinguishable plant material due to the insufficient regulatory procedures of processed medicinal plant products. Thus, it is important to develop a molecular assay based on species-specific nucleotide signatures and primers to efficiently distinguish authentic Pinelliae Rhizoma from its adulterants.

Methods and results
