Hypericum triquetrifolium Turra. (Hypericaceae) is one of the important medicinal plants. This herb used in Turkish folk medicine for its antidepressant, anthelmintic and antiseptic effects. extracts have an commercial value pharmaceutical industry. Therefore, studies to increase amount secondary metabolites it contains are becoming widespread. Elicitors biological non-biological factors that c...

The eudicot order Malpighiales contains ∼16000 species and is the most poorly resolved large rosid clade. To clarify phylogenetic relationships in the order, we used maximum likelihood, Bayesian, and parsimony analyses of DNA sequence data from 13 gene regions, totaling 15604 bp, and representing all three genomic compartments (i.e., plastid: atpB, matK, ndhF, and rbcL; mitochondrial: ccmB, cob...

We investigated the reproductive biology of three plants endemic to rosemary scrub habitats on the Lake Wales Ridge of Florida, USA. We used hand-pollination experiments and observations of flowers and their insect visitors to determine their mating systems and pollination. Fruit or seed set after self pollination was 94, 97, and 8% of fruit or seed set after cross pollination in Eryngium cunei...

Three Hypericum perforatum L., Hypericaceae (St. John’s Wort) oil extracts (HPE) were prepared according to the prescriptions from traditional medicine – fresh flowering tops were macerated in three different vegetable oils: sunflower (E1), olive (E2) and palm oil (E3) for 40 days, exposed to the sunlight. The aim of the study was to investigate the gastroprotective activity of the obtained ext...

Hypericum perforatum, known as St. John's Wort and most used ethnaformacolgically, belongs to the Hypericaceae family. In this work, we aimed evaluate antioxidant, antimicrobial, DNA protective activities, enzyme inhibitor properties of domestic import H. perforatum aqueous extracts. The total phenolic flavonoid contents were also determined for both samples. Results exhibited a high content Do...

Abstract Plants that produce secondary metabolites with allelopathic activity or phytotoxicity can be biotechnologically important, serving as sources of allelochemicals, and thus contributing to the agroindustrial sector. Vismia japurensis (Hypericaceae) is an Amazonian species grows in clumps called vismiais, from which most other plants are absent. Accordingly, objective this study was ident...
