Abstract
⺠The study involves authentication of taste variants of Gynostemma pentaphyllum (jiaogulan) herbal tea. ⺠No existing method is available to differentiate the bitter and sweet taste variants of jiaogulan. ⺠We find that the taste variants can be differentiated by HPLC-MS profiles of the plant saponins. ⺠Sequencing of the ribosomal DNA reveals a phylogenic distinction between the two variants.
