摘 要 目的 建立同时测定续断药材中6个环烯醚萜类成分(马钱苷酸、马钱子苷、当药苷、续断苷B、续断苷A、林生续断苷Ⅰ)
和 1 个三萜皂苷类成分(川续断皂苷Ⅵ)含量的方法。方法 采用高效液相色谱(HPLC)法。以 Symmetry C18为色谱柱,以乙

ABSTRACT OBJECTIVE To establish the method for the simultaneous determination of six iridoids(loganic acid,loganin,
sweroside,dipsanoside B,dipsanoside A,sylvestroside Ⅰ)and one triterpene saponin(asperosaponin Ⅵ)in Dipsacus asper.
METHODS High performance liquid chromatography (HPLC) method was adopted. The determination was performed on
Symmetry C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution(gradient elution)at the flow rate
®
of 1.0 mL/min. The detection wavelengths were set at 212 nm(asperosaponin Ⅵ)and 237 nm(dipsanoside B,dipsanoside A,
sweroside,loganic acid,sylvestroside Ⅰ ,loganin). The column temperature was set at 30 ℃ ,and sample size was 20 μ L.
RESULTS The linear range of loganic acid, loganin, sweroside, sylvestroside Ⅰ , dipsanoside B, dipsanoside A and
asperosaponin Ⅵ were 399.24-931.56,50.30-150.90,48.24-168.84,27.00-70.20,12.93-38.80,40.64-121.92,42.08-147.28 µg/mL
(all r>0.999 0). RSDs of precision,reproducibility and stability tests(24 h)were all less than 2%. Average recoveries were
104.43%(RSD=0.63%,n=6),101.74%(RSD=1.11%,n=6),100.76%(RSD=1.06%,n=6),98.00%(RSD=1.58%,n=6),
99.03%(RSD=2.31%,n=6),102.93%(RSD=2.26%,n=6),102.31%(RSD=1.00%,n=6),respectively,The contents were
142.5-280.6,5.5-49.0,28.0-112.9,7.2-35.8,4.4-16.9,17.2-79.3,0.8-54.5 mg/g,respectively. CONCLUSIONS Established
method is accurate and reliable,and can be used for the content determination of 7 components in D. asper.
