Concentrations of eight phenolics, acteoside (1), baicalin (2), wogonin 7-glucuronide (3), baicalein (4), wogonin (5), skullcapflavone I (6), skullcapflavone II (7) and chrysin (8) in shoot cultures of nine Scutellaria species were determined. The nine species were classified into four groups on the basis of the major phenolics in shoot cultures, i. e., (A) S. iyoensis and S. ventenatii of which major phenolics were 1,3 and 5, (B) S. lateriflora of which major phenolics were 4 and 5, (C) S. incana, S. orientalis and 5. taurica of which major phenolics were 3 and 5 and (D) S. pontica, S. galericulata and 5. alpina of which major phenolic was 1. On the other hand, callus cultures of seven Scutellaria species produced 1 as the major phenolic. In the S. iyoensis callus, the maximum concentration was 4.04 % in the light and 4.06 % in the dark.
