[Objectives] To establish a method for the determination of active components in toad skin. [Methods] HPLC method was used to determine the content of five active components (bufotalin, cinobufotalin, bufalin, cinobufagin and resibufogenin) in toad skin. [Results] Chromatographic conditions are as follows: Agilent ZORBAX SB-C 18 chromatographic column was used;acetonitrile (A)-0.3% glacial acetic acid (B) gradient elution (0-15 min, 28%A-54%A;15-35 min, 54%A-54%A) was conducted;the flow rate was 0.6 mL/min;the detection wavelength was 296 nm;the column temperature was 30 ℃;the sample size was 10 μL. Under the above conditions, the determination method of the five components can be established at one time. [Conclusions] The method was stable and reliable, and can provide experimental basis for the development and utilization of active ingredients in toad skin. 展开更多

[Objectives] To increase the reserves distribution and planting area of Ferula resources,protect wild Ferula resources,make comparative analysis on wild and cultivated varieties of Ferula medicinal materials,and provide references for quality evaluation of Ferula herbs collected from cultivation environment. [Methods] Volatile oil determination and high performance liquid chromatography were used to measure volatile oil and ferulic acid in different parts of wild and cultivated varieties of Ferula. [Results] In the volatile oil measured from artificially pressed Ferula lipid,wild varieties in different places conformed to the pharmacopoeia standard( volatile oil content ≥10%); in cultivated varieties,F. fukanensis K. M. Shen and F. sinkiangensis K. M. shen reached the pharmacopoeia standard. According to measurement results of ferulic acid,the ferulic acid content of roots and leaves of Altay,Fukang,and Yining cultivars were higher than that of wild varieties. [Conclusions]The ferulic medicinal herbs collected from artificial cultivation environment have considerable prospect,and many parts of Ferula herbs can be used for raw materials for preparation of extracts. 展开更多
