Aim: We tested the hypothesis that cardioprotection afforded by traditional Chinese Guanxin II (GXII) formula is related to absorbed bioactive compounds (ABCs).
Methods: Sprague-Dawley rats with acute myocardial infarction (AMI) were induced by coronary occlusion. ABCs including ferulic acid (F), hydroxyl safflor yellow A (A), tanshinol (T), protocatechualdehyde (P) and paeoniflorin (E) were measured in blood after oral GXII. The effects of GXII and FATPE, alone and in combination, and of some components of FATPE on infarct size, myocardial apoptosis and caspase-3 activity were determined. Myocardial blood flow (MBF) in AMI rat was detected 2h after oral GXII and FAT.
Results: FATPE was found in rat blood. FAT was similar to FATPE and GXII in decreasing infarct size, myocardial apoptosis and caspase-3 activity of AMI. Both FAT and GXII were similar in increasing of MBF.
Conclusion: GXII and FAT protect the heart from ischemic injury by increasing MBF, and decrease infarct size by inhibiting myocardial apoptosis and caspase-3 activity. These findings provide a potential cardioprotective cocktail.
