Determination of Karanjin in Radix of Fofdia Caulifora by Thin Layer Chromatograph- Fluorescent Method / 中国中医药信息杂志

Objective To establish a thin layer Chromatograph-Fluores cent method for the determination of karanjin in Radix of Fofdia caulifora. Methods Anhydrous-EtOH is solution, thin-sheet is silica gel, expanding solution is Benzene-EtoAc (8.5∶1.5), with excitation wavelength at 355 nm and emission wavelength at 428 nm. Results The average recovery of karanjin was 99.14% and RSD was 1.94% (n =5). There is a good linear relationship within the range of 0.138～0.69 ?g of karanjin. Conclusion The method is convenient, sensitive, accurate and reproducible, and can be used the quality control of the Radix of Fofdia caulifora.
