Studies on Chemical Constituents of Immunity Composite Decoction

Objective:To study the chemical constituents of immunity composite decoction.Method:The constituents were separated and purified by column chromatography on microporous resin,silica gel,RP-silica gel and sephadex LH20.Their structures were elucidated on the basis of spectra data.Result:Ten compound were isolated and identified as ethyl caffeate(1),pelargidenon(2),methyl salvianolate A(3),salvianolic acid N(4),rosmarinic acid(5),salvianolic acid A(6),methyl litospermate B(7),salvianolic acid B(8),galloylpaeoniflorin(9),succinic acid(10).Conclusion: All of compounds were isolated from immunity composite decotion for the first time,among them compound 1-7 were from Salvia miltiorrhiza,compound 8 was from Paeonia suffruticosa,compound 9 and compound 10 were from Leonto podium leonto podioid.
