Abstract:
OBJECTIVE:To establish a method for content determination of rosmarinic acid and total polysaccharide in Hysso-pus. offcinalis. METHODS:HPLC was conducted to determine the content of rosmarinic acid in H. offcinalis. The column was Shim-pack VP-ODS with mobile phase of acetonitrile-0.5% formic(17:83,V/V) at flow rate of 1.0 ml/min,detection wavelength was 330 nm,column temperature was 30 ℃,and the injection volume was 10 μl. UV-visible spectrophotometry was conducted to determine the content of total polysaccharide,detection wavelength was 620 nm. RESULTS:The linear range was 10.86-54.30 μg/ml (r=0.999 8)for rosmarinic acid and 1.996-15.97 μg/ml for total polysaccharide(r=0.999 6);RSDs of precision,stability and re-producibility tests were lower than 1.0% and 2.0%,respectively;recoveries were 98.20%-101.79%(RSD=1.68%,n=6) and 96.62%-101.68%(RSD=1.88%,n=6). CONCLUSIONS:The method is simple and reproducible,and can be used for the con-tents determination of rosmarinic acid and total polysaccharide in H. offcinalis.
