ABSTRACT
Objective To establish the GC fingerprint analysis for the quality control of volatile oil in Radix Bupleuri. Methods The GC with capillary column DB-1 (30 m?0.25 mm?0.25 ?m) was used. The column was maintained at 50 ℃ for 5 min after injection then programmed at 3 ℃/min to 170 ℃ and at 5 ℃/min to 230 ℃ which was maintained for 5 min. Gasification temperature 250 ℃, carrier gas N_2, flow rate 1.03 mL/min, inlet volumn 0.5 ?L, spliting ratio 10∶1, FID Injector temperature 250 ℃. The internal standard was [WTBX]n-nonane used to determine 25 batches of Radix Bupleuri from different habitats by GC fingerprint. Results The 25 batches of Radix Bupleuri are classified to be the qualified and unqualified based on the results of cluster and similarity analyses. Conclusion The method is simple and reliable and it is capable of effectively controlling the quality of Radix Bupleuri.
