Abstract:
The HPLC-ELSD method was used in the content determination of astragaloside, astragalosideⅠ, astragalosideⅡand astragalosideⅢ in Mongolia Radix Astragali (Astragalus membranaceus(Fisch.) Bge. var. mongholicus(Bge.) Hsiao) among 16 batches from various habitats. The DIKMA Diamonsil C18 (150 mm× 4.6 mm, 5μm) was adopted with acetonitrile and water as the mobile phase at a gradient mode program. The flow rate was 1.0 mL·min-1. And the column temperature was 30℃. The ELSD detector parameters were the drift tube temperature at 90℃, and the air flow rate of 2.8 L·min-1. The SPSS 16.0 software was used in the cluster analysis of content determination. The results showed that when the injection volume was within the range of 0.093 2-1.02μg (r = 0.999 5), 0.789-8.78μg (r = 0.999 7), 0.506-3.13μg (r = 0.999 6), and 0.016 1-1.38μg (r = 0.999 2) for astragaloside, astragalosideⅠ, astragalosideⅡ and astragalosideⅢ, respectively, the average recoveries were 97.55%, 98.61%, 99.68%, 98.58%with RSD of 1.2%, 1.3%, 1.3%, 1.2%, respectively. The results of cluster analysis showed that the single using of astragaloside as index was unable to differentiate Mongolia Radix Astragali from various habitats. However, the simultaneous determination of 4 types of astragalosides as indexes can differentiate Mongolia Radix Astragali from various habitats. It was concluded that the method was simple, quick and accurate, which can directly reflect the quality status of Mongolia Radix Astragali from different origins. It also provided new ideas for the quality control of Mongolia Radix Astragali.
