    摘要: The present invention provides a method for making hypericin comprising the steps of converting a protohypericin to a protohypericin salt, and irradiating the protohypericin salt with visible light to form hypericin. The present invention also provides an apparatus comprising a transparent column having a top end and a bottom end, an inlet attached to the column at the top end to flow reactants into the column, a container attached to the column at the bottom end; and a visible light source positioned to cast light on to the column. The present invention further provides a method for making hypericin using said apparatus.
