Traceability of Volatile Organic Compounds from Hypericum perforatum in Fresh and Dried Form and in Essential Oil

Abstract: Microextraction in solid phase from headspace and GC-MS analysis was the method of studying the flowers of Hypericum perforatum in fresh and dry form.The essential oil obtained by hydrodistillation was also analyzed by GC-MS. Identification of the substances was made by comparison of mass spectra with NIST library and standard alkanes were used for the calculation of the linear retention index. The identified compounds were grouped into classes of substances: monoterpene hydrocarbons, sesquiterpene hy… Show more

“…The plant can be prepared as a powdered herbal substance, dry extract, liquid extract with different extraction solvents (suitable vegetable oils or ethanol), tincture, expressed juice or comminuted herbal substance-all of which can be represented differently in the pharmaceutical form: liquid or semi-solid dosage forms as well as herbal teas for oral use [2]. St. John's wort is used in the treatment of inflammation, bacterial and viral infections, as well as eczema, burns, neuralgia, ulcers and gastroenteritis [3]. Its use increases the feeling of satiety; therefore, it is gaining higher popularity as a curative agent against obesity-associated complications [4,5].…”
