摘  要:目的:建立HPLC-ELSD法同时测定细柱五加果实中的竹节参苷Ⅳa和3β-([O-β-D-glucopyranuronosyl]oxy)-olean-12-ene-28-olc acid含量的方法。方法:采用反相高效液相色谱-蒸发光散射检测法。色谱条件AlltimaTM-C18色谱柱(4.6mm×250 mm,5μm),流动相乙腈(A)-0.5%乙酸水溶液(B),柱温35℃。ELSD检测器条件:漂移管温度106℃,载气氮气,流速2.9 L.min-1,放大系数1,撞击器关闭。结果:竹节参苷Ⅳa和3β-([O-β-D-glucopyranu ronosyl]oxy)-olean-12-ene-28-olcacid的进样量分别在0.535~8.560μg(r=0.996 5)和0.515~8.240μg(r=0.9987)呈良好线性关系;平均回收率(n=6)分别为98.39%,98.97%,RSD分别为1.50%,1.59%。结论:方法准确、灵敏,可用于测定细柱五加果实中竹节参苷Ⅳa和3β-([O-β-D-glucopyranu-ronosyl]oxy)-olean-12-ene-28-olc acid的含量。Objective: To establish an I-IPLC-ELSD method for the simultaneous determination of the content of chikusetsusaponin IV a and 3β-( [ O-β-D-glucopyranuronosyl] oxy) -olean-12-ene-28-olc acid in the fruits of Acanthopanax gracilistylus. Method: The RP-HPLC-ELSD method was used. Chromatographic conditions : AlltimaTM-C18 chromatographic column (4.6 mm×250 mm, 5 μm) ; acetonitrile (A) -0.5% acetic acid water (B) as mobile phase; column temperature at 35 ℃. ELSD detector conditions : drift tube temperature : 106 ℃; carrier gas (nitrogen)flow rate: 2.9 L .min^(-1); amplification factor: 1; impactor: close. Result: The calibration curves showed good linear relationship in the range from 0. 535 to 8. 560 μg (r = 0. 996 5) for chikusetsusaponin Iva and 0. 515 to 8. 240 μg (r = 0. 998 7) for 3β- ( [ O-β-D-glucopyranuronosyl] oxy) -olean- olean-28-olc acid. The average recovery rates (n =6) were 98.39% and 98.97% , and RSDs were 1.50% and 1.59%. Conclusion: This method is accurate, sensitive and can be used to determine the content of chikusetsusaponin IV a and 3β- ( [ O-β-D-glucopyranuronosyl] oxy) -olean-12-ene-28-olc acid in the fruits of Acanthopanax gracilistylus.
