【摘要】 目的:建立关苍术的高效液相色谱(HPLC)指纹图谱,并测定关苍术中白术内酯Ⅰ和Ⅲ的含量。方法:指纹图谱和含量测定研究的色谱柱分别为KromasilC18(250mm×4.6mm,5μm)和ODSHypersilC18(250mm×4.6mm,5μm),检测波长分别为240nm和220nm,流动相分别为水-乙腈(梯度洗脱)和甲醇-水(60:40,V/V),流速为1mL.min-1,进样量为10μL。结果:关苍术指纹图谱中共标定了9个共有指纹峰,10批样品的相似度均>0.9。白术内酯Ⅰ和Ⅲ的进样量分别在50.1～417.5ng(r=0.9997)和49.5～412.5ng(r=0.9998)范围内与各自峰面积积分值呈良好线性关系,平均加样回收率分别为101.02%和97.12%,RSD分别为4.32%和4.01%(n均为9)。结论:所建指纹图谱具有较好的精密度、重复性和稳定性;所建含量测定方法简单、灵敏、结果可靠,均可用于关苍术的品质评价和质量控制。 更多还原

【Abstract】 OBJECTIVE:To establish HPLC fingerprint of Atractylodes japonica,and to determine the contents of atractylenolideⅠand atractylenolide Ⅲ in A.japonica.METHODS:Fingerprint study and content determination were performed on Kromasil C 18 column(250 mm×4.6 mm,5 μm)and ODS Hypersil C 18 column(250 mm×4.6 mm,5 μm);the detection wavelength was set at 240 nm and 220 nm;mobile phase consisted of water-acetonitrile(gradient elution)and methanol-water(60:40,V/V)at the flow rate of 1 mL.min-1.The injection volume was 10 μL.RESULTS:There were 9 common peaks in the fingerprints of A.japonica,and the similarity of 10 batches of samples was higher than 0.9.The linear ranges were 50.1～417.5 ng(r=0.999 7)for atractylenolideⅠand 49.5～412.5 ng(r=0.999 8)for atractylenolide Ⅲ.The average recoveries were 101.02% and 97.12%,and RSDs were 4.32% and 4.01%,respectively(n=9).CONCLUSION:Established fingerprint has good precision,reproducibility and stability;the method is simple,sensitive and reliable.It is suitable for quality evaluation and control of A.japonica.
