In order to improve the qualities of boiling extract the availability of standard compounds was investigated in extract of Scutellariae Radix. The standard compounds used baicalin(1), baicalein(2), and wogonin(3). The availabilities were analyzed by thin layer chromatography (TLC) and high performance liquid chromatography(HPLC) on $C_18$ column. The extract of RS-4(W/V=10g/100m1) showed the highest availabilities as 7.95% of baicalin(1), 1.04% of baicatein(2), and 0.31% of wogonin(3).
