Isolation procedures of two new acylphloroglucinols, myrtucommulone-A and myrtucommulone-B, from Myrtus communis leaves are given. Myrtucommulone-A was highly antibacterial against gram-positive bacteria but was not active against gram negatives. The chemical relation to other acylphloroglucinols and the antibacterial activity of the compounds isolated are discussed.

Long-distance migration is a behavior that is exhibited by many animal groups. The evolution of novel migration routes can play an important role in range expansions, ecological interactions, and speciation. New migration routes may evolve in response to selection in favor of reducing distance between breeding and wintering areas, or avoiding navigational barriers. Many migratory changes are li...

results the minimal inhibitory concentration (mics) values of myrtus communis leaves extract ranged 0.625-5.0 µg/µl and 5-40 µg/µl against tested candida spp. and aspergillus spp., respectively. conclusions results revealed that the ethanolic extract of myrtus communis leaves have antifungal potency against both pathogenic tested fungi, and it can be used as a natural antifungal agent. material...

Meadow vole food preferences were examined by means of a serie s of two day trials where pairs of plants were offered. Of the six plants tested, three (white clover, red clover, alfalfa) were found to be highly preferred by the voles, one (red fuscue) was acceptable, and two species (myrtle and crownvetch) were unacceptable. The results suggest that the undesirable groundcovers may be used as a...

Anti-Planktonic and Anti-Biofilm Formation Activities of the Essential Oil Hydroalcoholic Extract Myrtus communis L. Leaves Fruits Against Clinical Candida species

Several animal species have recently been shown to have hybrid origins, but no avian examples have been documented with molecular evidence. We investigate whether the Audubon's warbler (Dendroica auduboni), one of four visually distinct species in the yellow-rumped warbler complex, has originated through hybridization between two other species in this group, the myrtle warbler (D. coronata) and...

Anthropogenic habitat deterioration can promote changes in plant mating systems that subsequently may affect progeny performance, thereby conditioning plant recruitment for the next generation. However, very few studies yet tested mating system parameters other than outcrossing rates; and the direct effects of the genetic diversity of the pollen received by maternal plants (i.e. correlated pate...

Myrtus communis L. young and mature Leaves were collected in Fars (the southern province of Iran). The aim of this research was to investigate essential oil content and composition of myrtle leaves which were at different ontogeny stages. Essential oil was extracted by hydrodistillation method using Clevenger apparatus, the oils were analyzed by GC–MS. Highest content of essential oil were reco...
