The flowers and leaves of the plant contain a volatile oil rich in hydrocarbons called "Red Hypericum." It also contains pseudohypericin, the most important of which are: herpesin, naphthone, dianthrone, naphthodinarton compounds (a red pigment), hyperforin (naphthodianthrones), phloroglucinol derivatives such as herpeforin, catechin tannins such as quercitrin, rutin, amentoflavone, and hyperoside (hyperin): of which 4% are flavonoids, 7-15% are catechin tannins, chlorogenic acid, caffeic acid, and organic acid derivatives such as caffeic acid, linoleic acid, and 30% palmitic acid.
The flowering tops contain a fixed oil, the most important fatty acids of which are palmitic acid and 13% linoleic acid.
The oil is prepared by soaking a quantity of flowers in olive oil: in a sealed bottle under strong sunlight for several weeks until the oil turns the color of blood, then it is strained and used.
