Abstract��OBJECTIVE To study the high-performance thin layer chromatographic (HPTLC) fingerprint of volatile oil constituents from Amomum villousm and its related species so as to set up the identification protocol of the medicinal plant and provide scientific information for its quality control.METHODS TLC was used to analyze comparatively 10 batches of Amomum villosum Lour.samples, 10 batches of Amomum villousm crude drugs collected from different producing areas and stored for different time, 10 batches of the fruits of counterfeit species and 10 kinds of related species in the Zingiberaceae family.The samples were separated on silica gel G precoated plates with a mixture of cyclohexane-chloroform-ethyl acetate (13:2:2) as developing solvent system. The relative humidity was 67%. The spots were visualized with 5% vanillin sulfuric acid solution, then were analyzed by utilizing CHROMAP 1.5 solution software.RESULTS The fingerprint of volatile oil of Amomum villosum , with 9 specific bands examined under natural light, was set up. The quality of Amomum villosum stored for different time or collected from different areas was distinctly variable.Obvious difference existed in the chemical composition of the volatile oils between Amomum villosum and its counterfeit and other related species. CONCLUSION The HPTLC fingerprint analysis method can be used for rapid identification and quality control of Amomum villosum .
