Bioactivity-guided fractionation
A step-by-step method of finding the active chemical in a plant. You test the plant extract for activity (e.g., kills malaria parasite), then split the extract into parts (fractions), test each part, keep only the active part, split it again, and repeat until you get one pure active compound. The biological test "guides" the separation at every step.

Fraction
A portion of a mixture obtained during separation. Like cutting a cake into slices — each slice is a fraction of the whole cake.
