摘 要:目的:对桃儿七中的4种主要木脂素类成分鬼臼毒苷(化合物Ⅰ)、4′-去甲基鬼臼毒素(化合物Ⅱ)、鬼臼毒素(化合物Ⅲ)和去氧鬼臼毒素(化合物Ⅳ)进行含量测定。方法:采用反相高效液相色谱法,使用ZORBAX SB C18柱(250mm×4.6mm,5μm),流动相为乙腈-水,线性梯度洗脱(0~13min,25∶75;13~20min,30∶70;20~30min,32∶68;30~32min,50∶50),流速1.2mL.min-1,检测波长290nm,柱温25℃。结果:化合物Ⅰ~Ⅳ进样量均在0.05~5.0μg范围内有良好的线性关系(r≥0.9999,n=7);化合物Ⅰ~Ⅳ的平均回收率(n=6)分别为102.2%,101.0%,99.8%,102.6%,RSD分别为0.56%,1.9%,0.87%,1.9%。结论:本方法能够准确地测定桃儿七中的4种主要木脂素类化合物的含量。Objective: To determine four lignans [ podophyllotoxin - 4 - O - β - D - glucopyranoside ( compound I ), 4 ‘- demethylpodophyllotoxin ( compound Ⅱ ), podophyllotoxin ( compound Ⅲ ) and deoxypodophyllotoxin (compound Ⅳ ) ] in Sinopodophyllum emodi Wall.. Methods : The separation was performed with RP - HPLC on ZORBAX SB Clscoloum (250 mm ×4. 6 ram,5 μm) , using a mixture of acetonitrile -water as the mobile phase with gradient elution (0 - 13 min, 25: 75 ; 13 - 20min, 30:70 ; 20 - 30 rain, 32: 68 ; 30 - 32 min, 50:50 ) ; The flow rate was 1.2 mL ·min- 1 at 25 ℃, the wavelength for measurement was 290 nm. Results:The linearity was in the range of 0. 05 - 5.0 p^g ( n = 7 ) for compounds Ⅰ - Ⅳ, and all the correlation coefficients were higher than 0. 9999 ; The average recoveries ( n = 6) for compoundsⅠ - Ⅳ were : 102.2% ( RSD = 0.56% ), 101.0% ( RSD = 1.9% ) ,99. 8% (RSD =0. 87% ), 102.6% ( RSD = 1.9% ) respectively. Conclusion: This method is accurate to determine four lignans in SinopodophyUum emodi Wall.
