Antihepatoma peptide, scolopentide, derived from the centipede scolopendra subspinipes mutilans

Figure 2 Characterization of extracted scolopentide and detection of synthetic scolopentide. A: Mass spectrum of extracted scolopentide; the highest peak indicates the active peptide (scolopentide). The observed molecular weight was 1018.997 Da; the asterisk “*” means molecular structure of scolopentide; B: Mass spectrum of synthetic scolopentide. The observed molecular weight was 1018.8 Da; C and D: HPLC chromatogram of synthetic scolopentide (C); the highest peak (peak 3) indicates the active peptide, and the area % of peak 3 indicates the purity of synthetic scolopentide (98.014%) (D).
