摘要目的: 建立山紫菀藥材的質量標準。方法:

採用薄層色譜法(tlc)對藥材樣品進行定性鑑別;測定藥材樣品水分、灰分、浸出物的含量;採用高效液相色譜法測定藥材樣品中阿魏酸的含量,色譜柱為waters sunfire c18, 流動相為乙腈-0.1%磷酸溶液(13 ∶ 87,v/v),流速為1.0 ml/min,檢測波長為319 nm,柱溫為30 ℃,進樣量為10 l。

結果:山紫菀的tlc圖斑點清晰,分離度好,陰性對照無干擾。藥材樣品水分為7.

6%~9.4%,總灰分為11.7%~19.

6%,酸不溶性灰分為5.9%~14.1%,浸出物為25.

4%~37.5%。阿魏酸檢測進樣量線性範圍為0.

021 2~0.636 8 g(r=0.999 9);定量限為2.

25 ng,檢測限為0.75 ng;中間精密度、重複性、穩定性試驗的rsd均小於3.0%;加樣**率為97.

81%~100.59%(rsd=1.02%,n=9)。

結論:初步擬定山紫菀藥材水分不得過10.0%,總灰分不得過19.

0%,酸不溶性成分不得過12.0%,浸出物不得少於25.0%,阿魏酸含量不得少於0.

1%;所建標準可為山紫菀藥材的質量控制提供參考。

abstract objective: to establish the quality standard of ligularia fischeri. methods:

tlc was used for qualitative identification of samples. the contents of moisture, ash and extract were determined. the content of ferulic acid in samples was determined by hplc.

the determination was performed on waters sunfire c18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid (13 ∶ 87,v/v) at the flow rate of 1.0 ml/min.

the detection w**elength was set at 319 nm, and column temperature was 30 ℃. the sample size was 10 l. results:

tlc spots were clear and well-separated without interference from genitive control. the moisture, total ash, acid-insoluble ash and extract of samples were 7.6%-9.

4%, 11.7%-19.6%, 5.

9%-14.1% and 25.4%-37.

5%, respectively. the linear range of ferulic acid were 0.021 2-0.

636 8 g(r=0.999 9). limited of quantation was 2.

25 ng, the limited of detection was 0.75 ng. rsds of intermediate precision, reproducibility and stability tests were all lower than 3.

0%. the recoveries ranged 97.81%-100.

59%(rsd=1.02%,n=9). conclusions:

the moisture, total ash and acid-insoluble ash of samples are no more than 10.0%, 19.0%, 12.

0%; the extract and the content of ferulic acid are no less than 25.0% and 0.1%.

established standard can provide reference for quality control of l. fischeri.
