HPLC fingerprint of Radix astragali from n-Butanol extract of Danggui Buxue Decoction / 中成药

ABSTRACT

AIM: To study the main components of the position of n-Butanol extract of Danggui Buxie Decoction(Radix Astragali,Radix Angelicae Sinensis). METHODS: The main components were determined by HPLC.HPLC with Nucleodur C18 Gravity column was used,the Acetonitrile-water(gradient elution) was used as a mobile phase and detecting wavelength at 210 nm. RESULTS: There were 14 common peaks in the peak position of n-Butanol extract of Danggui Buxue Decoction,Radix astragli had 14 peaks and Radix angelicae sinensis 3 peaks. CONCLUSION: The main components of the peak position among n-Butanol extract of Radix astragali and its extract and Danggui Buxie Decoction have correlation.
