Myrtucyclitones A-C ((+)-and (-) -1 - 3 ), three pairs of new triketone-phloroglucinol-triketone hybrids were isolated from the plant Myrtus communis . Their structures with absolute configurations were established by NMR analysis and chemical calculations. Myrtucyclitones B and C exhibited

M yrtucomvalones D-F ( 1 - 3 ), three new triketone-phloroglucinol-triketone adduct s, and three known ones ( 4 - 6 ) were obtained from Myrtus communis 'Variegata'. Compound 1 is a pair of enantiomers which was further resolved into (+)- 1 and (-)- 1 by chiral HPLC. Their structures and complete

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

OBJECTIVE To evaluate the antibacterial activity of the essential oil of Myrtus communis (M. communis) L. against Erysipelothrix rhusiopathiae (E. rhusiopathiae) in vitro. METHODS Wild populations of M. communis collected from Khuzestan and Lorestan provinces, Southwest Iran, were examined for

Our continuation on the bio-assay guided isolation from Myrtus communis Linn. led to the discovery of a new dibezofuran type phloroglucinol 1,1'-(1,3,7,9-tetrahydroxydibenzo[b,d]furan-2,8-diyl)bis(ethan-1-one) 1. The structure was established through detailed spectroscopic studies including one and

BACKGROUND Myrtle "Addus" (Myrtus communis) has long history as a traditional medicine/or different infectious disease by many peoples of the world and in Ethiopia too. OBJECTIVE To asses the antibacterial activity of crude myrtle on some common human pathogens. METHODS This experimental study was

In this study, fractional compound composition, antioxidant capacity, and phenolic substance content of 14 plant essential oils-anise (Pimpinella anisum), bay leaves (Laurus nobilis), cinnamon bark (Cinnamomum verum), clove (Eugenia caryophyllata), fennel (Foeniculum vulgare), hop (Humulus lupulus),

UNASSIGNED Anaerobic Gram negative bacteria are the main cause of periodontal destruction. It has been shown that Myrtus communis have anti-bacterial activity on Gram positive and Gram negative bacteria. The aim of this study was to determine the antibacterial effect of aquatic and methanolic

An investigation of the polar glycosidic fraction from the leaves of myrtle afforded four galloylated nonprenylated phloroglucinol glucosides (3a-d) related to the endoperoxide hormone G3 (4) in terms of structure and biogenesis. Despite their close similarity, significant antibacterial activity was

BACKGROUND The extended-spectrum beta-lactamase (ESBL) -producing Escherichia coli isolates make many serious infections, especially urinary tract infections. OBJECTIVE The purpose of this study was to determine the antibacterial activities of some natural plant extracts against ESBL-producing E.

BACKGROUND Aeromonas hydrophila cause one of the most important diseases in fishes and lead to economic losses, and may be contaminated human beings. OBJECTIVE The current research aimed to investigate the anti-bacterial activity shown by the extracts prepared from different parts of Olea europea,

Fifty methanolic plant extracts belonging to 44 plant species of 33 families finding use in Iranian folkloric medicine were screened for antibacterial activity. Thirty samples, including 28 species in 20 families, had antibacterial activity against at least on one of the bacteria. Among the active

The present study examined the effects of dietary Myrtle (Myrtus communis L.) on non-specific immune parameters and bactericidal activity of skin mucus in rainbow trout (Oncorhynchus mykiss) fingerlings. Three hundred and sixty fingerlings (6.50 ± 0.55 g (were distributed in twelve cages (65 × 65 ×

Medicinal plants are targeted in the search for new antimicrobial agents. Nowadays, there is an alarmingly increasing antimicrobial resistance to available agents with a very slow development of new antimicrobials. It is, therefore, necessary to extensively search for new agents based on the
