The structure of astrachrysosid A and the study of 2D-NMR on astrasieversianin XV and 7,2'-dihydroxy-3',4'-dimethoxy-isoflavane-7-O-β-D-glycoside
Yao xue xue bao = Acta pharmaceutica Sinica [Chinese] 25 (1990)
445-450
Six compounds were isolated from the root of Astragalus chrysopterus Bunge. One of them was identified as a new triterpenoid glycoside, named astrachrysoside A. Its structure was elucidated as 3-O-[α-L-rhamnopyranosyl (1----2) β-D-xylopyranosyl]-cycloastragenol on the basis of physicochemical evidence and chemical reactions. The others were shown to be known compounds, astrasieversianin XV (II), 7,2'-dihydroxy-3',4'-dimethoxy-isoflavane-7-O-β-D-glucoside (III), soyasaponin I, daucosterol and β-sitosterol. Full assignment of the chemical shift signals of II and III were established by various 2D-NMR techniques.

A precolumn derivatization high-performance liquid chromatographic method with improved sensitivity and specificity for the determination of astragaloside IV in Radix astragali
Journal of Chromatographic Science 38(8) (2000)
325-328
A reversed-phase high-performance liquid chromatographic method is developed for the determination of astragaloside (AGS) IV, which is known as the active constituent of Radix Astragali. The method uses precolumn derivatization with benzoyl chloride to form the benzoyl ester of AGS IV quantitatively and is carried out with a wide-ranging concentration (0.004-0.080 mg/mL) of the derivatized AGS IV. The eluent consists of 90% methanol, 4% tetrahydrofuran, 6% water, and 0.2% triethylamine, with vitamin D3 added as the internal standard.
