ABSTRACT
OBJECTIVE:
To establish the quality standard for Gastrodia elata hency-fired tablet.METHODS:
TLC was used to identify the gastrodin and benzyl alcohol and determine the content of moisture,ash and extract;HPLC was used to determine the content of gastrodin and benzyl alcohol. Column was Diamonsil C18 with mobile phase of acetonitrile-0.05% phosphate(397,V/V) at flow rate of 1.0 ml/min,detection wavelength was 220 nm,column temperature was 25 ℃ and volume injection was 10 μl. RE-SULTSThe TLC of gastrodin and benzyl alcohol showed clear spots and good separation. The moisture content40.0%. Linear range of gastrodin was 25.2-126.0,12.7-63.5 μg/ml(r=0.999 9),respectively;RSDs of precision,reproducibility and stability tests were lower than 2.0%;recovery was 99.49%-102.40%(RSD=1.09%,n=6), 98.75-102.63%(RSD=1.53,n=6),respectively.CONCLUSIONS:
