cistus libanotis/抗菌的

Seven labdane-type diterpenoids were isolated from the leaves of Cistus incanus subsp. creticus; their structures were established by spectroscopic means. All compounds were tested in vitro for their cytotoxicity against three cell line systems: KB, P-388; and NSCLC-N6. Their antibacterial and

The main aim of this study was to detect and identify antibacterial components of fraction I derived from eleven commercial C. incanus herbal teas. Fraction I obtained by a well-established phytochemical protocol of a multi-step extraction was expected to contain flavonoid aglycons alone.

In this study, the antimicrobial activity of leaf extracts obtained from two species of genus Cistus L. was examined in vitro against five strains of bacteria and five strains of fungi. The species studied are Cistus villosus L. = incanus and Cistus monspeliensis L. All extracts showed inhibitory

The Mediterranean plant Cistus incanus is rich in polyphenols and has shown several pharmacological activities, mainly antibacterial effects. Furthermore, in situ studies revealed that a C. incanus infusion reduces the initial bacterial adhesion in the oral cavity due to the polyphenols, an

Propolis is a beehive product with a very complex chemical composition, used since ancient times in several therapeutic treatments. As a contribution to the improvement of drugs against several tropical diseases caused by protozoa, we screened Portuguese propolis and its potential floral sources

Cistaceae is a large family of shrubs commonly distributed in the Mediterranean ecosystem. The aim of this study was to explore the potential antimicrobial properties against Escherichia coli and/or Staphylococcus aureus of different extracts obtained from four Cistaceae species that are especially

Plant polyphenols are a potential source of new antimicrobial molecules against bacteria because most newly developed antimicrobial agents do not improve the clinical management of infectious diseases. The potential synergism between the major polyphenolic compounds present in a Cistus salviifolius

Essential oils (EOs) from Eucalyptus globulus Labill. ssp. globulus and from Mediterranean autochthonous aromatic plants - Thymus mastichina L., Mentha pulegium L., Rosmarinus officinalis L., Calamintha nepeta (L.) Savi ssp. nepeta, Cistus ladanifer L., Foeniculum vulgare L., Dittrichia viscosa (L.)

Cistus creticus ssp. creticus is an indigenous shrub of the Mediterranean area. The glandular trichomes covering its leaf surfaces secrete a resin called "ladanum", which among others contains a number of specific labdane-type diterpenes that exhibit antibacterial and antifungal action as well as in

Plants, and specially species adapted in non-friendly environments, produce secondary metabolites that help them to cope with biotic or abiotic stresses. These metabolites could be of great pharmaceutical interest because several of those show cytotoxic, antibacterial or antioxidant activities.

Cistus creticus subsp. creticus is a plant of intrinsic scientific interest due to the distinctive pharmaceutical properties of its resin. Labdane-type diterpenes, the main constituents of the resin, exhibit considerable antibacterial and cytotoxic activities. In this study chemical analysis of

The structure of a novel CC clerodane type diterpenoid, namely (+)-19-acetoxy-cis-clerodan-3-ene-15-oic acid 1 was elucidated and its conformational properties were explored using a combination of high field NMR spectroscopy and computational analysis. The structural analysis provided results

The chemical composition of the essential oil of the leaves of Cistus creticus subsp. eriocephalus (Viv.) Greuter & Burdet, (Cistaceae), was investigated by GC/MS. Thirty-nine components were identified, representing 73.9% (based on % total peak area by GC) of the oil composition. The main

Borreliosis patients from self-help groups reported considerable pain relief after ingestion of Cistus creticus leaf preparations. C. creticus leaf extracts of different polarities such as aqueous, ethyl acetate, hexane extracts as well as the volatile oil fraction obtained by steam distillation

Chronic obstructive pulmonary disease (COPD) is characterized by abnormal inflammation and impaired airway immunity, providing an opportunistic platform for nontypeable Haemophilus influenzae (NTHi) infection. In this context, therapies targeting not only overactive inflammation without
