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

Acinetobacter baumannii is a rapidly emerging, highly resistant clinical pathogen with increasing prevalence. In recent years, the limited number of antimicrobial agents available for treatment of infections with multi-drug resistant (MDR) strains reinforced tendency for discovery of novel

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

BACKGROUND Recent works present evidence of Propionibacterium acnes growing as a biofilm in cutaneous follicles. This formation of clusters is now considered as an explanation for the in vivo resistance of P. acnes to the main antimicrobials prescribed in acne vulgaris. OBJECTIVE Our objective was

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

To increase the sensibility of Salmonella typhimurium strain, a mixture of Thymus vulgaris L. (T. vulgaris L.), Rosmarinus officinalis L. (R. officinalis L.) and Myrtus communis L. (M. communis L.) essential oils (EOs) was used in combined treatment by experimental design methodology (mixture

Medicinal plants have always had an important place in the therapeutic arsenal of humanity and particularly in the treatment of gastrointestinal tract diseases. Myrtus communis L., known as common myrtle, is native to Southern Europe, North Africa, and Western Asia. The different parts of this plant

BACKGROUND Myrtus communis L. (Myrtaceae), myrtle, is an evergreen shrub with strong antibacterial, anti-inflammatory, antihyperglycemic and antioxidant activities. Also, it is used as a sedative-hypnotic plant in Iranian traditional medicine. OBJECTIVE This study evaluates the effect of 80%
