ABSTRACT
To investigate the quality of different parts of Radix Fici Hirtae. The content and components of volatile oils and ethanol-extracts from different parts of Radix Fici Hirtae were analyzed by the combination of gas chromatography and mass spectrometry (GC-MS). The content of volatile oils in the cortex was higher than that in the xylem and the chemical components either in the cortex or in the xylem are similar. The main components in volatile oils are hexadecanoic acid, oleic acid+linoleic acid, linoleic acid amide, palmitic acid amide,stearic acid amide and dibutyl phthalate. The main components in ethanol-extracts are psoralen, hexadecanoic acid, hexadecanoic acid ethyl ester, bergapten, oleic acid and linoleic acid. The content of psoralen in the cortex was higher than that in the xylem.[Conclusion]The chemical components in different parts of Radix Fici Hirtae are similar but the contents of volatile components and psoralen are higher in the cortex than those in the xylem.
