compounds collectively referred to as "Pyrethrins". The
pyrethrum flower isyellow at itscentral part andconsequently
thepyrethrum extractisyellow incolour.Theintensity ofthe
yellowness inextracts,mainlyattributedtothepresenceofthe
carotenoidal andflavonoidalpigmentsfoundinpyrethrumflowers
has been visually observed to relate closely to the Pyrethrins
content but no analyticalverification ofthisobservationhas
