The aim of the present study was to investigate chemical composition and antibacterial activity of essential oil from the leaf of Mentha spicata plant against common food-borne pathogenic bacteria (Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Listeria monocytogenes, Salmonella typhimurium, and Escherichia coli O157:H7). Chemical composition of the essential oil was identified by g...

A comparative study was performed on 12 species of the genus Veronica L. (Plantaginaceae sensu APG 2003, formerly Scrophulariaceae) namely Veronica persica, V. bachofenii, V. urticifolia, V. agrestis, V. austriaca, V. chamaedrys, V. officinalis, V. orchidea, V. spicata, V. beccabunga, V. hederifolia, V. prostrata. In these species we have determined the aucubin and catalpol content by using a H...

Lessonia spicata is a key dominant species along the Pacific coast of South America, providing a habitat for many organisms. However, this role can be affected by abiotic stress, such as metals. To counteract the toxic effect, L. spicata, among other seaweeds, releases exudates that bind metals. In this study, tolerances to copper of organisms related to the kelp forest (spores of Ulva lactuca ...

Actaea spicata Linn. (Ranunculaceae) has been traditionally used for the treatment of various ailments such as rheumatism, inflammation, nerve diseases, lumbago, scrofula and chorea, but no systematic phytochemical and pharmacological work has ever been carried out on this potential plant. Preliminary phytochemical screening showed presence of phenols and flavonoids in A. spicata. Thus, the pre...

Article history: Received on: 25/12/2013 Revised on: 08/02/2014 Accepted on: 23/05/2014 Available online: 28/06/2014 The effect of tissue cultured and tissue culture derived Mentha species viz. Mentha piperita(PPR611), Mentha arvensis (SH) and Mentha spicata (SPR 8) on antioxidant potential using lipid peroxidation model was studied. The extracts prepared were analyzed for total phenols and fla...

It has been hypothesized that species occurring in the eastern and the western Qinghai-Tibet Plateau (QTP) responded differently to climate changes during the Pleistocene. Here, we test this hypothesis by phylogeographic analysis of two sister species, Allium cyathophorum and A. spicata. We sequenced two chloroplast DNA (cpDNA) fragments (accD-psaI and the rpl16 intron) of 150 individuals, and ...
