Solubility of hypericin in methanol and methanol-pyridine.

Abstract

The solubility of hypericin in methanol and methanol-pyridine (99:1, v/v) was determined. The addition of pyridine turned out to enhance the solubility of hypericin. In pure methanol only 37.17 micrograms/ml could be dissolved. In comparison, 320.91 micrograms hypericin were soluble in one ml methanol-pyridine (99:1, v/v).
