Abstract

Recoveries of representative pesticides showing a large recovery difference greater than 25% depending on extraction solvents which are acetonitrile (ACN), ACN/ethyl acetate (EA) (7:3, v/v), ACN/EA (3:7, v/v), and EA in C. officinale (a), R. glutinosa (b), and P. lactiflora (c). The error bars are the standard deviations of the recoveries (n = 3). The dotted lines mean the recovery of 70%.</p
