ABSTRACT
The effects of Rhynchophylline (Rhy) and Isorhychophyiline (Isorhy), the alkaloids abstracted from the Chinese traditional herb Uncaria rhynchophyllia (Miq) Jackson, on the 45Ca-influx and efflux were investigated in rabbit aorta. Both Rhy and Isorhy (10 ?mol? L-1) inhibited the 45Ca-influx induced by high K+(77. 0 mmol ? L-1), but neither significant-ly influenced the 45Ca-influx and efflux induced by noradrenaline (10 ?mol ? L-1). The results suggest that these alkaloids block the Voltage-dependent calcium channel.
