Abstract:
An in vitro screening model was applied to test the inhibitory activities of 17 Salvia species on protein tyrosine phosphatase 1B (PTP1B). Root methanol extracts from wild-collected Salvia species were analyzed using this model. Most of the samples tested showed positive activities on human PTP1B. The inhibition rates of Salvia crude extracts varied from 9.76% to 100% at 30 microg x mL(-1), with the most convincing effects coming from Salvia evansiana and Salvia castanea. HPLC analysis revealed seven components shared by Salvia samples could be related to the inhibitory activities.
