【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.

【药理作用】白术内酯ⅰ能促进胃肠道消化吸收功能,是白术键脾的有效成分之-.具有抗炎、抗肿瘤作用,该成分还具有调节胃肠道功能和促进营养物质吸收的功能。
