Figure 1. Lowering SBP effect of single oral administration of IPPVPP and VPPIPP on SHR spontaneously hypertensive rats.

IPPVPP, VPPIPP, and IPP (the positive control) were fed to the three groups of SHR with at a dose of 1.5 mg/kg BW, respectively; the distilled water as the control was fed to a SHR group at the same dosage. The SBP was expressed as mean ± SD. Points with the same letters mean no significant difference (P<0.05).
