Fig. 1From: In vitro effects of aqueous extract from Maytenus senegalensis (Lam.) Exell stem bark on egg hatching, larval migration and adult worms of Haemonchus contortusHPLC-ESI/MSn base peak chromatograms (BPC) of the aqueous extract of Maytenus senegalensis. In the negative ionization mode (ESI−) MS1 spectrum, the most intense peak corresponded to the deprotonated molecular ion [M-H]− or formate adduct [M + HCOOH-H]Back to article page
