The antihypertensive mechanism was studied of the ethyl acetate fraction of the ethanol extract (EAPF) of Gardenia jasminoides var. radicans Makino (GJRM). GJRM is a fake product of Gardenia jasminoides Ellis (G. jasminoides), but in China's Henan province, the production of GJRM is much more than G. jasminoides's, but its traditional usage is as a dye. Gardenia jasminoides can be used to reduce blood pressure and blood glucose levels. The chemical compositions of GJRM and G. jasminoides are similar, and we previously confirmed that GJRM can also reduce blood pressure. Here, we report that the EAPF of GJRM could activate the phosphoinositide 3-kinases (PI3K) pathway in the kidneys of spontaneously hypertensive rats, thus increasing the content of nitric oxide and bradykinin in sera and decreasing endothelin-1 content. EAPF can also decrease the levels of with-no-lysine kinase 1 (WNK1) expression, WNK4 and oxidative stress-responsive kinase 1 messenger ribonucleic acid (mRNA), and Na-K-2Cl cotransporter and sodium chloride cotransporters mRNA and phosphorylation. To investigate the antihypertensive effects of the EAPF of GJRM, 5 monoterpenoids isolated from EAPF were studied for their effects on NRK52e and IMCD3 cells. These compounds inhibited the PI3K-WNK signaling pathway to varying degrees under hypotonic conditions; 4-methoxyrehmapicrogenin had the best effect.
