Protein kinase inhibition of different solvent extracts of H. rosea.

Protein kinase inhibition activity
Plant extracts	Zone of inhibition in mm at 100 µg/disc
n-Hexane (HR-1)	—
Ethyl acetate (HR-2)	—
Chloroform (HR-3)	22.0
n-Butanol (HR-4)	—

Note. indicates significant results (). The chloroform extract exhibited significantly () higher protein kinase activity compared to surfactin standard.
