Induction of phenolic compounds in Hypericum perforatum L. cells by Colletotrichum gloeosporioides elicitation.

Changes in phenolic metabolism after elicitation with Colletotrichum gloeosporioides (CG) has been studied in Hypericum perforatum L. (HP) cell suspension cultures. Soluble phenolics were analysed by HPLC-DAD and HPLC-DAD-MS/MS. HP cultures elicited with the CG elicitor showed a significant increase in xanthone accumulation. Xanthone accumulation increased twelve fold when the cells were primed...

Antioxidant activity relationship of phenolic compounds in Hypericum perforatum L.

BACKGROUND The St John's Wort (Hypericum perforatum; Clusiaceae) has been used in traditional and modern medicine for a long time due to its high content of biologically active phenolics. The purpose of this work was to develop a method for their fractionation and identification, and to determine the most active antioxidant compounds in plant extract. RESULTS An LC-MS method which enables fas...

Phenolic Acids and Flavonoids in Hypericum Perforatum L. Hairy Roots

Investigations have been made to develop an efficient protocol for identification and quantification of phenolic acids and flavonoids in hairy roots (HR) of Hypericum perforatum L. HR were induced from root segments of in vitro grown seedlings from H. perforatum, after co-cultivation with Agrobacterium rhizogenes A4. Transgenic status of HR was confirmed by PCR analysis using rolB specific prim...

Induction of Phenolic Compounds is Affected by Boron Supply in Marshmallow (Althaea officinalis L. ) Cells

Boron (B) is a non-metal micronutrient which is essential for plants growth and development. Formation of boron complex with cell wall matrix and phenolic compounds is a definite influence of boron in physiological process. It has been suggested that B-toxicity and deficiency may induce excess production of reactive oxygen species thereby promote defense responses by antioxidant enzymes or non-...

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...
