Headspace solid phase micro extraction gas chromatography (HS-SPME-GC), which was an improved method of the usual HS-GC was applied to the analyses of components in crude drugs, such as Asiasari Radix. The crude drug (0.20g) was preheated with 1.0ml of water in a capped vial at 50℃ for 25 min and the SPME fiber was injected into the vial. Then vaporized components were adsorbed and extracted with the fiber at 50℃ for 5 min. The fiber was injected into the injection port of GC at 220℃ for 30s. The results indicated that HS-SPME method was sensitive and rapid analysis for crude drugs under moderate conditions, and this technique described in this paper, therefore, will become a powerful method for quality control of components in crude drugs.
