摘要: The effects of 17 flavonoids, isolated from two flavonoid-rich Scutellaria species (Scutellaria baicalensis Georgi and Scutellaria rivularis Wall) used in traditional Chinese medicine, on HL-60 cells were assessed by WST-8. Ten of the flavonoids inhibited the proliferation of HL-60, as shown by IC50 values used as indexes of the inhibition. 2′, 3′, 5, 7-tetrahydroxy flavone (IC50= 9.5 μM), apigenin (15.0 μM), viscidulin III (17.4 μM), wogonin (17.4 μM) and luteolin (18.4 μM) were more effective than baicalein (23.0 μM) which reportedly inhibits the …
