Objective: To study the effects of auxin on the active compounds and endogenous hormones in Scutellaria baicalensis suspension cell cultures. Method: The subculture scutellariae callus were cultivated in MS liquid medium containing various concentration of NAA or KT on a gyratory shaker with a 16-h photoperiod. After 18 d
the contents of baicalin and endogenous hormones were determined with HPLC and enzyme-linked immunosorbent assay
respectively. Darkness condition was as control. Result: (1) After 0.2 mg ·L-1 NAA treatment
the content of baicalin was 2.56% and 3.36% lower than of untreatment
respectively. (2) After NAA treatment on the dark conditions
the content of ZR was significantly reduced. (3) The synergistic effect of 0.2 mg ·L-1 NAA with different concentration of KT on the content of baicalin presented the trend of rising then declined. And after 1.0 mg ·L-1 KT treatment
the content of baicalin was the highest levels on the dark conditions and significantly higher than light condition. Conclusion: Auxin is not suitable for the active compound production of S. baicalensis. The combination of 0.2 mg ·L-1 NAA+1.0 mg ·L-1 KT promotes the accumulation of baicalin.
