Objective: To establish methodologically a method for quantitative determination of beta-eudesmol in Atractylodes lancea.
Method: GC, column: 3 mm x 2 m; stationary phase; 15% QF-1; support: Chromosorb WAW(60-80 mesh); detector: hydrogen flame ionization detector; injection chamber temperature: 210 degrees C; column temperature: 174 degrees C; carrier gas: N2:50 ml.min-1, air: 49 kPa, H2:58.8 kPa; sensibility range: 10(2) x 64; chart speed: 2.5 mm.min-1.
Result: Average recovery ratio is 100.7% (n = 5).
Conclusion: This method can be used to control the quality of A. lancea.
