Identification and determination of hypericine in the extracts of the amber - Hypericum perforatum L. ssp. angustifolium


, : Identification and determination of hypericine in the extracts of the amber - Hypericum perforatum L. ssp. angustifolium. Hemijska Industrija 54(7/8): 327-329

Extracts were obtained from H. perforatum subsp. angustifolium (amber), collected from Serbia, Yugoslavia, by maceration, ultrasonic maceration, or extraction with CO2 under high pressure. The highest yields of dry extract were achieved with ultrasonic maceration (23.3%) and conventional maceration (22.9%) methods. Freytag's HPLC method was used to determine the hypericin content in methanol ultrasonic macerate (0.039%) and in methanol macerate (0.036%).
