Metabolic stability of A. brassicicola for CPT production with the subculturing and storage. The cultures of A. brassicicola was incubated at standard conditions, CPT was extracted and quantified by TLC and HPLC. The yield of CPT of A. brassicicola in response to subculturing (A), and storage for 12 months as slope culture (B). The upper panels are the TLC and lower panels were the yield quantified by Image J. The yield of CPT by the 6th culture generation of A. brassicicola amended with different extracts (C) and surface sterilized leaves of C. roseus (D)
