Essential oil composition of Hypericum perforatum L. and Hypericum scabrum L. growing wild in Tajikistan
The essential oils obtained by hydrodistillation from the aerial parts of Hypericum perforatum L. and Hypericum scabrum L. from plants growing wild in Tajikistan were analyzed by GC-MS. Sixty-six compounds were identified in the essential oils of H. perforatum with germacrene D (13.7%), α-pinene (5.1%), (E)-caryophyllene (4.7%), n-dodecanol (4.5%), caryophyllene oxide (4.2%), bicyclogermacrene ...
متن کاملHypericin and pseudohypericin in some Hypericum species.
Hypericin and pseudohypericin were found in 27 of the 36 evaluated species from Hypericum L., belonging to 17 sections of the genus. Pseudohypericin is reported by us in 15 taxa for the first time. Most of the species contained both components and the amount of pseudohypericin usually exceeded that of hypericin. In H. hirsutum and H. empetrifolium only hypericin was found, whereas H. formosissi...
متن کاملPharmacological activities of Hypericum scabrum L.
OBJECTIVES Hypericum spp. (H.) has been used in traditional medicine for their sedative effect for many years. In spite of many works on this genus, little is known about H. scabrum. In this work antidepressant and its protective effect against hypoxia-induced lethality were evaluated. MATERIALS AND METHODS Antidepressant and its protective effects against hypoxia-induced lethality were evalu...
متن کاملModeling the Altitudinal Variation in Secondary Metabolite Contents of Hypericum Orientale from Turkey
In the present study, models were developed to estimate the altitudinal variation in secondary metabolite contents of Hypericum orientale growing wild in “Güldağı” mountain, Turkey. Aerial parts of flowering 30 individuals were collected at six different altitudes (500, 1150, 1650, 2100, 2720 and 3250 m). Actual secondary metabolite contents of plants were measured by High Performance Liquid Ch...
متن کاملCytotoxic Activity and Apoptosis Induction of Hypericum scabrum L.
BACKGROUND One of the acquired biological hallmarks of tumor multistep development is the resistance of cancer cells to apoptosis; therefore, induction of apoptosis is an important therapeutic approach. Hypericum species are spread throughout the world and have been investigated for their biological properties. OBJECTIVES Our previous studies had demonstrated cytotoxicity of Hypericum scabrum...
