Three kinds of callus tissues(S.b.p, S.b.c and S.b.r), derived from petiole, cotyledon, and root of a young plant of Scutellaria baicalensis were assayed for their biologically active flavonoid productions. The baicalin and baicalein contents of the extracts of S.b.p, S.b.c and S.b.r cultured cells were measured by HPLC. The baicalin contents in fresh S.b.p, S.b. c and S.b.r were 8.5, 7.1 and 0.6 % g/dw, respectively and the baicalein contents of the same extracts 0.3, 1.2 and 0.2% g/dw, respectively. After drying at 60℃, the baicalin content of S. b. c decreased to 0.3% g/dw with an increase in the baicalein content to 2.9 % g/dw, but the baicalin and baicalein contents of S.b.p did not change after drying. On the other hand, in S.b.r both, baicalin and baicalein almost disappeared. It is of interest that the three kinds of callus tissues obtained from the same original plant have different productivity for baicalin and baicalein.
