This paper presents a review of scientific studies analyzing the biological properties of different species of Cistus sp. Materials and methods. Forty papers that discuss the current research of Cistus sp. as phytotherapeutic agent were used for this discussion. Literature analysis. The results of scientific research indicate that extracts from various species of Cistus sp. exhibit antioxidant, antibacterial, antifungal, anti-inflammatory, antiviral, cytotoxic and anticancer properties. These properties give rise to the pos- sibility of using Cistus sp. as a therapeutic agent supporting many therapies.

  • Germination Behaviour of Four Mediterranean Cistus L. Species in Relation to High Temperature
    Ecological Questions 12/2010 – Special Issue: 175 – 186 DOI: 10.2478/v10090–010–0011–2 Germination behaviour of four mediterranean Cistus L. species in relation to high temperature Domenica Scuderi, Rosa Di Gregorio, Stefania Toscano, Carla Cassaniti, Daniela Romano Department of Horticulture and Food Technology, University of Catania, Via Valdisavoia 5, 95123 Catania, Italy, e-mail: [email protected] Abstract. Cistus is one of the most characteristic genera of the Mediterranean flora. These species, natives of lands surrounding the Mediterranean Sea, are present in scrubland and garigue on siliceous ground and often on acid soil; seven species in particular are founded in Sicily. The adaptation of the genus to Mediterranean environments is evident from ecological characteristics such as fire- dependent seed germination; the heat generated by fire is in fact a key germination input. In this view, two experiments were performed to study the effects of high temperature on germination of four Cistus species (C. creti- cus L., C. crispus L., C. monspeliensis L., C. salviifolius L.). In the first, in relation to untreated control, 7 different high temperature pre-treatments (from 70°C to 130°C) for different timings (from 1 to 10 minutes) were analysed in relation to two sowing strategies (soon after the seed collection and after a 6 month period at 5°C to simulate the winter season effects). The pre-treatment with high temperatures can improve the germination; the storage at 5°C to simulate the winter season effects did not modify the germination process. In any case the results showed a species-dependent response.

Available Online: 01st April, 2016 ABSTRACT The objective of this study was to evaluate antimicrobial and antifungal activities of crude extracts from leaves and flower of Halimium halimifolium, and compared with those of Cistus salviifolius and Cistus monspeliensis. The tested plants (leaves and flowers) were extracted with ethanol, the activities were screened against three Gram-positive (Listeria monocytogenes, Bacillus subtilis and staphylococcus aureus), three Gram-negative bacteria (Salmonella enteric, Pseudomonas aeruginosa and Escherichia coli), and two pathogenic fungi (Candida albicans and Aspergillus niger). The efficacy of these extracts was tested against those microorganisms through a disc-diffusion method employing 15 휇L of each sample per paper discs (6 mm in diameter). Comparable results were carried out using Gentamicin and Amphotericin as standard antibiotics. Ethanol extracts of different parts of plant exhibited good activity against all microorganisms tested.

  • The British Forms of Tuberaria Guttata (L.) Fourreau
    THE BRITISH FORMS OF TUBERARIA GUTTATA (L.) FOURREAU By M. C. F. PROCTOR Department of Botany, University of Exeter ABSTRACT An account is given of the variation in British Tuberaria guttata, and of its previous taxonomic treat­ ment: the taxonomic value of various characters is examined. Most of the Welsh and Irish plants includ­ ing the type population of Helianthemum breweri Planch. differ from T. guttata as it occurs in the Channel Isles and northern France in their shorter stature, the more common presence of bracts and other characters. All the characters said to distinguish breweri intergrade continuously with those of typical guttata in both herbarium and cultivated material, and are only loosely correlated. The more compact Welsh and Irish plants appear to be comparable with plants in similar exposed coastal habitats in north-west France. It is concluded that T. guttata shows ecotypic differentiation in relation to exposure on the Atlantic coast of Europe, and that the populations combining short diffuse habit and numerous bracts may be of polytopic origin. It is suggested that they should not be given formal taxonomic recognition. 1. INTRODUCTION Like a number of other widespread Mediterranean species, Tuberaria guttata extends northwards up the west coast of Europe to a northern limit in the British Isles. Up to the north coast of France its distribution is more or less continuous, and the Channel Islands lie on the northern fringe of this essentially continuous area. But north of the English Channel its range is disjunct, and it occurs only in widely separated colonies on the coasts of north Wales and western Ireland.

Faculté des Sciences, LBVRN ; Laboratoire de Biotechnologie et Valorisation des Ressources Naturelles, BP 8106, cité Dakhla, Agadir, 80 000, Morocco. Accepted 23 June, 2011 In search for alternative ways of tomatoes’ bacterial canker control, we screened here forty medicinal and aromatic plants (MAP) sampled from 15 families, currently used in southern Moroccan traditional medicine, for their activity against Clavibacter michiganensis subsp . michiganensis the causal agent of this disease. The antibacterial efficacy of powders of these plants was determined in vitro using the agar plate’s methods. Results obtained show that all the forty plants tested inhibited the bacterial growth of this pathogen with inhibition zone diameter ranging from 5 to 50 mm. Determination of the minimal inhibitory concentrations (MIC) and the minimal bactericidal concentrations (MBC) of the most effective plants indicates that there plants gender Rubus, Anvillea and Pistacia have the lower MIC which is equal to 3,125 mg ml -1. The other plants ( Lavandula coronopifolia, Lavandula stoechas, Rosa canina, Cistus monspliensis and Cistus crispus ) had a MIC equal to 6.25 mg ml -1. The MBC for different plants tested are between 6.25 mg ml -1, case of Rubus ulmifolius and 25 mg ml -1.

Thorogood, [email protected] Received 2 September 2007; Accepted 14 December 2007 Recommended by John J. Wiens Host specificity in the parasitic plant Cytinus hypocistis was quantified at four sites in the Algarve region of Portugal from 2002 to 2007. The parasite was found to be locally host specific, and only two hosts were consistently infected: Halimium halimifolium and Cistus monspeliensis. C. hypocistis did not infect hosts in proportion to their abundance; at three sites, 100% of parasites occurred on H. halimifolium which represented just 42.4%, 3% and 19.7% of potential hosts available, respectively. At the remaining site, where H. halimifolium was absent, 100% of parasites occurred on C. monspeliensis which represented 81.1% of potential hosts available. Other species of potential host were consistently uninfected irrespective of their abundance. Ecological niche divergence of host plants H. halimifolium and C. monspeliensis may isolate host-specific races of C. hypocistis, thereby potentially driving al- lopatric divergence in this parasitic plant.

Hence, these issues cannot be neglected when plan- ning conservation actions for isolated populations. The Italian population of Cistus laurifolius subsp. lau- rifolius is extremely isolated. Furthermore, it is affected by fragmentation, being constituted by a single larger subpopulation, surrounded by three much smaller subpopulations, a few hundred metres to a few kilometres apart.
