The Biological Activities of Hypericum Perforatum L.
BACKGROUND Mastitis reduces milk yield and alters milk composition. Antibiotics are widely used in the treatment of the disease. However, this widespread use of antibiotics causes both antibiotic residues in milks and antibiotic resistance developed in bacteria. Today's researches are focused on discovering and using new antibiotics against bacteria. OBJECTIVE The aim of this work was to disc...
متن کاملComparative phytochemical and antimicrobial investigations of Hypericum perforatum L. subsp. perforatum and H. perforatum subsp. angustifolium (DC.) Gaudin.
The aerial parts of H. perforatum subsp. perforatum and H. perforatum subsp. angustifolium were investigated for their chemical composition and antimicrobial activity. Spectrophotometric analysis indicated that H. perforatum subsp. perforatum is richer in flavonoids and tannins than the other subspecies. HPLC analysis confirmed the higher yield of flavonoids in H. perforatum subsp. perforatum a...
متن کاملEssential 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 کاملA review of the antibacterial activity of Hypericum perforatum L.
Hypericum perforatum L. (Hypericaceae) is a perennial herb that is commonly known as St. John's Wort. The plant has been valued for its important biological and chemical perspectives and its use in the treatment of infectious diseases has been documented in ethnobotanical reports. Most recent interest in H. perforatum has focused on its antidepressant effects, and only recently has its antimicr...
متن کاملAnalysis of Breeding Systems, Ploidy, and the Role of Hexaploids in Three Hypericum perforatum L. Populations.
Hexaploid seeds are produced by predominantly tetraploid populations of Hypericum perforatum, but the fate of hexaploid seedlings and their reproductive behavior have not been closely examined. We used flow cytometry to analyze single seeds and individual plant samples of three accessions of H. perforatum to determine ploidy levels and reproductive pathways. Seed samples of all three accessions...
