Effects of active components of Radix Scrophulariae (ACRS) on cardiac mass index of spontaneously hypertensive rats (SHR) and Wistar–Kyoto rats (WKY) ($\overline{x}$ ± SE, n = 8)

Group	LVWI (mg/g)	HWI (mg/g)
WKY control	2.36 ± 0.15	3.02 ± 0.19
WKY+ 140 mg/kg ACRS	2.49 ± 0.43	3.28 ± 0.85
SHR control	3.09 ± 0.24††	3.75 ± 0.24††
SHR+ 40 mg/kg captopril	2.50 ± 0.09**	3.15 ± 0.13**
SHR+ 70 mg/kg ACRS	2.80 ± 0.11**	3.35 ± 0.11**
