摘 要 目的 提升毛大丁草药材的质量标准。方法 观察毛大丁草药材的性状并对其粉末进行显微鉴别;按 2020 年版《中国药
典》(四部)通则方法测定该药材中的水分、总灰分、酸不溶性灰分和醇溶性浸出物;采用高效液相色谱法测定该药材中紫花前胡
苷、木犀草素-7-O-β-D-芦丁糖苷、木犀草苷、芹菜素-7-O-β-D-芦丁糖苷、芹菜素-7-O-β-D-葡萄糖苷、异紫花前胡内酯的含量。结果
毛大丁草药材呈皱缩状,密被灰白色绵毛;须根多数,表面呈灰褐色或灰棕色,质脆,易折断,断面呈黄白色,中央有一明显细小木
心。其粉末呈棕褐色,镜下可见非腺毛、石细胞、草酸钙方晶、导管、纤维等。15批药材样品的水分、总灰分、酸不溶性灰分、醇溶
性浸出物测定值分别为 8.63%~11.34%、10.39%~14.93%、3.29%~6.37%、9.03%~15.02%,平均值分别为 10.01%、12.26%、
4.61%、12.36%。紫花前胡苷、木犀草素-7-O-β-D-芦丁糖苷、木犀草苷、芹菜素-7-O-β-D-芦丁糖苷、芹菜素-7-O-β-D-葡萄糖苷、异
紫花前胡内酯的质量浓度分别在 3.87~154.88、1.64~65.41、1.60~64.00、1.92~76.96、1.27~50.93、0.40~15.89 μg/mL 范围内与
各自峰面积成良好的线性关系(r均不低于0.999 1);精密度、稳定性(24 h)、重复性试验的RSD均小于3%;平均加样回收率分别
为 101.88%、100.89%、102.64%、95.75%、96.71%、103.48%,RSD 分别为 0.55%、0.43%、0.34%、0.49%、0.47%、0.37%(n=6);样
品中上述6种成分的含量分别为0.152 7~0.852 2、0.084 5~0.669 7、0.136 7~0.961 0、0.126 0~1.193 2、0.128 8~1.102 2、0.046 9~
0.678 0 mg/g。结论 所建方法可用于毛大丁草药材的质量控制。初步拟定毛大丁草药材中水分不得过 12.0%,总灰分不得过
15.0%,酸不溶性灰分不得过6.0%,醇溶性浸出物不得少于9.0%,木犀草苷、芹菜素-7-O-β-D-葡萄糖苷的含量不得少于0.016%。

ABSTRACT OBJECTIVE To improve the quality standard for Gerbera piloselloides. METHODS The properties of G.
piloselloides were observed and microscopic identification was conducted for powder. The moisture,total ash,acid-insoluble ash
and ethanol-soluble extract were detected according to the method stated in 2020 edition of Chinese Pharmacopoeia(part Ⅳ). The
contents of nodakenin,luteolin-7-O-β-D-lutinoside,luteoloside,apigenin-7-O-β-D-lutinoside,apigenin-7-O-β-D-glucopyranoside and
marmesin were determined by high performance liquid chromatography method. RESULTS G. piloselloides were shrunken,densely
covered with thick white cotton wool,with many fibrous roots;the surface was taupe or gray-brown;its texture was brittle and
easy to break;the cross section was yellow-white,and there was an obvious small wooden heart in the center. Its powder was tan,
and non-glandular hairs,stone cells,calcium oxalate cubes,ducts,fibers could be seen under microscope. The measured values of
moisture,total ash,acid-insoluble ash and alcohol-soluble extract
