ABSTRACT
Object To determine and compare the content of polysaccharides in three species of Semen Plantaginis from different places of origin. Methods Spectrophotometry was used. Results The content of polysaccharides in the seed of Plantago major L. was higher than those in the seed of P. asiatica L. and P. depressa Willd. Conclusion The content of polysaccharides in Semen Plantaginis of different species or origins are obviously different.
ABSTRACT
Objective:To determinate the content of vitexin in Xinan Capsules by RP HPLC.Methods: C 18 ODS(4.6mm?150mm;5?m) column with temperature at 25 ?C was used with a mobile phase of water zspropanol acetic acid(75∶18∶3) elution at the flow rate of 1mL -1 ?min -1 and detection wavelength at 330nm.Results: The linear range of vitexin was from 0.734 to 3.67 ?g, and correlation coefficient was 0.9996 . The content of vitexin in Xinan Capsules is 9.7%. Conclusions:The detection method is simple and convenient, accurate with a good reproducibility. The extraction method of the control sample is simple, and easy to do.
