Abstract
The invention discloses a measuring method for total cardiac glycoside content in Zhuang medicine streptocaulon griffithii. According to the method, color-developing agents are added into samples, thecontent of total cardiac glycoside in the streptocaulon griffithii is measured by an ultraviolet spectrophotometry after the samples develop color, test conditions include that Digoxin serves as a reference substance, alkaline picric acid solution serves as the color-developing agents, detection is performed under the wave length of 415nm, the content of the reference substance and the absorbancehave a good linear relation within the range of 0-0.08mg/ml, a regression equation y=14.968x+0.008 (r=0.9969), accuracy RSD=0.1%, average sample recovery ratio is 95.51%, RSD is 2.16% (n=6), and thetotal cardiac glycoside content in the streptocaulon griffithii is 2.07mg/g. The method is simple, rapid, accurate and good in repeatability and can be used for measuring the total cardiac glycoside content in the streptocaulon griffithii, and quality basis is provided for evaluation and control of the streptocaulon griffithii.
