the molar extinction coefficient of amentoflavone?
L’ assorbanza delle porfirine alla lunghezza d’onda
di 630 nm, che è utilizzata in applicazioni cliniche è piuttosto bassa e
caratterizzata da un coefficiente di estinzione molare inferiore a 103 M

Hello Gianna, you can calculate it by running a simple test on your spectrophotometer.
use the formula : ε=A/cl
