Objective:Study on extracting technology and assay of astragaloside in Astragalus.Method: 70% ethanol circumfluence extraction was used.Total astragaloside was enriched and purified by extraction refine through water saturated of n-butanol and D101 mcroporous adsorption resin.Different components of astragaloside were isolated by silica gel laminar analysis.Identification by using TLC method and determination the contents by u-sing HPLC-RID Method.Result: Six compounds were isolated from total astragaloside(AS-Ⅰ ~ AS-Ⅵ)
and 29.4% astragaloside Ⅱ was identified in As-Ⅰ part.AS-Ⅲ which content is 22.82% is mainly contained Astraga-losideⅣ by identification.The rest four compounds are required to be identified.Conclusion:The method can be used for astragaloside
HPLC-RID method can be used to determine the content of astragaloside.
