Rechromatography of purified 23.3-min fraction before and after UV light irradiation. (A) Before irradiation. (B) Chromatography of the same 23.3-min fraction after 366-nm UV light irradiation in vitro. The 23.3-min fraction is virtually abolished, and a major new species is generated. The photo-transformation product differs in its elution time (41.6 min) and spectral properties.
