Sibjotang Increases Atrial Natriuretic Peptide Secretion in Beating Rabbit Atria

Figure 2

HPLC profile and H NMR analysis of Sibjotang. (a) Chemical structures of compounds. Number 1 is salvianolic acid B, number 2 is rosmarinic acid, number 3 is apigenin 7-O-b-glucuronide, number 4 is yuankanin, and number 5 is apigenin. It is analyzed by 1D- and 2D-NMR data; (b) HPLC chromatographic profile of the extract of SJ. Peak numbers correspond to structures given in (a), and the identity of the compounds was confirmed by retention times of isolated compounds.
