Abstract
Propolis has multiple biological activities, and the high demand for it and limited availability have led to adulteration by poplar tree gum. In this survey, we used salicin as a marker to monitor the incidence of poplar tree gum in propolis semi-products or final products circulated in the Chinese market, using an HPLC method. A total of 67 samples were tested, and poplar tree gum was not detected in 23 of these samples. However, 66% of the samples did contain poplar tree gum. Of 50 finished propolis products from 26 manufacturers, salicin was present in 27 products from 13 manufacturers. The survey showed that products from the same manufacturer contained either real propolis or poplar tree gum product. Moreover, the concentrations of salicin varied in commercial propolis products from different manufacturers. This proposed method can be effectively used for detecting poplar tree gum in propolis products.
