To study the global diversity of plant-symbiotic nitrogen-fixing Frankia strains, a rapid method was used to isolate DNA from these actinomycetes in root nodules. The procedure used involved dissecting the symbiont from nodule lobes; ascorbic acid was used to maintain plant phenolic compounds in the reduced state. Genes for the small-subunit rRNA (16S ribosomal DNA) were amplified by the PCR, a...

This study has been carried out to evaluate the possible In vitro interaction between ethanolic extracts of Rus coriaria (seed), Sacropoterium spinosum (seed) and Rosa damascena (flower) and certain known antimicrobial drugs including oxytetracycline HCl, penicillin G, cephalexin, sulfadimethoxine as sodium and enrofloxacin. Synergy testing of these extracts and antibiotics was carried out agai...

Caesalpinia coriaria (C. coriaria), also named cascalote, has been known traditionally in México for having cicatrizing and inflammatory properties. Phytochemical reports on Caesalpinia species have identified a high content of phenolic compounds and shown antineoplastic effects against cancer cells. The aim of this study was to isolate and identify the active compounds of a water:acetone:ethan...

Pseudotutin previously isolated from Coriaria japonica A. GRAY was revealed to be a molecular compound consisting of equimolar tutin (2) and a new related sesquiterpene lactone, corianin (3). Corianin was also isolated together with coriamyrtin (1), tutin (2) and coriatin (4), from Loranthus parasiticus MERR., a parasitic plant that grows on the twigs of Coriaria sinica MAXIM. The structure of ...

The antimicrobial activities of 56 Palestinian medicinal plants against etiologic agents of acne vulgaris, mainly Propionibacterium acnes and Staphylococcus aureus was studied using disc diffusion and broth dilution methods. The results from the disc diffusion method demonstrated that these plants differ significantly in their activity against the studied microorganisms. The most active plants ...

In this experimental study, 30 adult male Wistar rats divided into 5 groups (n=6). Experimental rats were treated with one intraperitoneal injection of 120 mg/kgbw Alloxan monohydrate alone or in combination with 28 days of oral administration with aqueous extract of Rhus coriaria (50, 100 and 250 mg/kgbw) while the control rats received normal saline. At the end of the study, blood glucose, ma...

The fruits contain tannins (2), volatile oil (6, 7), various organic acids (2), anthocyanins (6) and fixed oil (6). Either the whole fruit or only the pericarp is used as a condiment in Turkey and called “Sumak” (2, 9). The composition of the essential oils prepared from the fruit, leaves and branch barks of R. coriaria has been reported on the same Anatolian material (7). The anatomical charac...

In our previous studies, we showed the inhibitory effects of Punica granatum L. flower and Rhus coriaria L. fruit water extracts on dental plaque accumulation by several bacteria, especially Streptococcus mutans (S. mutans), on orthodontic wire by in-vitro assays. In this study, the anti-cariogenic properties of the extracts were evaluated by assessing their effects on expression of glycosyltra...

rhus coriaria l. is known as sumac. r. coriaria extracts are important in drug development with numerous pharmacological reputations in the south-eastern anatolia, mediterranean area and western asia especially in iran. regarding the new multi-functional properties of r. coriaria and the related valuable ongoing reports, we were prompted to review the phytochemical and pharmacological propertie...
