Cardiovascular Activity of Labdane Diterpenes from Andrographis paniculata in Isolated Rat Hearts

Figure 2

The effects of diterpenoids isolated from the dichloromethane extract of A. paniculata, sodium nitroprusside (SNP), and 40% EtOH, on coronary perfusion pressure of isolated rat hearts. The results are expressed as mean ± s.e.m., *𝑃<0.05, student’s paired 𝑡-test, compounds versus vehicle (40% ethanol), 𝑛=7. Basal coronary perfusion pressure = 72.1±5.6 mm Hg.
