Isolation and purification of destruxin B from Metarhizium anisopliae fermentation broth. (a) Flowchart of the extraction and purification procedure. (b) HPLC chromatographic spectrum of purified destruxin B. Metarhizium anisopliae fermentation broth was centrifuged and filtered. The filtrate was extracted with CH2Cl2, and then the destruxin B was extracted and purified by ion-exchange chromatography, silica gel chromatography, and HPLC. (c) The chemical structure of destruxin B.
