Hypericin is a photosensitive principle of many Hypericum species, it is a very expensive natural compound, it undergoes a rapid oxidation process in light conditions if I work in normal condition in a phyto lab. Which source of light should I use in my lab "colour of light to minimize photosensitivity" ... is using a dem light useful?

You can extract photosensitive compound with methanol/water mixture in the dark at room temperature.Affinity chromatography is a very advantageous technique for this.
