“…As far as we know there are no reports on antifungal activity of the mentioned plant and the reports on phenolic composition refers to samples from Spain Barrajón-Catalán et al, 2010;Barrajón-Catalán et al, 2011). Herein, a screening of the antifungal potential of phenolic extracts of Cistus ladanifer against 4 Candida species was performed, and the extracts were further characterized by HPLC-DAD-ESI/MS.…”

The life-threatening mycoses caused by opportunistic fungal pathogens (mainly species from the genus Candida) associated with nosocomial infections, are one of the major health problems in our days. Therefore, it is crucial to identify new compounds, especially natural ones, that are active against the most broaden spectrum of Candida species. Herein, a screening of the antifungal potential of a phenolic extract of Cistus ladanifer from Northeastern Portugal, against Candida species was performed. Furthermore, the extract was characterized by HPLC-DAD-ESI/MS. Phenolic acids and derivatives (3.96 mg/g extract), ellagic acid derivatives (30.34 mg/g extract), and flavonoids (4.15 mg/g extract), such as catechins, flavonols and flavones, were found in the sample. The most abundant group was ellagic acid derivatives in which punicalagin gallate, a derivative of punicalagin attached to gallic acid, was found in highest amount (15.99 ± 0.02 mg/g extract). These compounds (i.e., ellagitannins) could be related to the strong inhibition of C. albicans, C. glabrata and C. parapsilosis growth (MIC < 0.05 mg/ml). Moreover, the best antifungal activity was against C. glabrata, where the studied extract was able to cause at least 3 Log of reduction at concentrations below 0.05 mg/mL and a total growth inhibition at concentrations above 0.625 mg/mL.

“…The use of pink rock-rose in therapy mainly results from its use in the traditional medicine of the Middle East, particularly Turkish medicine, where C. ×incanus was known as an anti-inflammatory agent in skin diseases, and as an antiulcer and antidiarrhea remedy; moreover, it was used in phytotherapy of rheumatism and nephritis [2,[4][5][6]. In addition, C. ×incanus is recommended as a compound in dietary supplements for the prevention of chronic diseases such as hypertension, diabetes, or Alzheimer's disease [2,4,[7][8][9][10].…”

In vitro cultures of Cistus ×incanus (pink rock-rose) were maintained on two variants of Murashige and Skoog (MS) medium differing in terms of composition of plant growth regulators (PGRs): 6-benzyl adenine (BA) and 1-naphthaleneacetic acid (NAA) at the following concentrations: 3 mg/L and 0, 3 mg/L and 1 mg/L, respectively, and on a variant without PGRs -a control. Cultures were maintained in a form of agar and agitated shoot cultures. The qualitative and quantitative analyzes of three groups of phenolic compounds (catechins, flavonoids, and free phenolic acids) were performed by using the HPLC-DAD technique in methanolic extracts of in vitro biomasses and of commercial plant raw material. In analyzed extracts from in vitro cultures, the presence of catechin [max. 197.80 mg / 100 g dry weight (DW)], epicatechin gallate (max. 30.74 mg / 100 g DW), gallic acid (max. 83.23 mg / 100 g DW), quercetin (max. 10.15 mg / 100 g DW), and quercitrin (max. 72.89 mg / 100 g DW) was confirmed. The quantities of accumulated compounds varied and depended on the type of in vitro culture and the concentration of PGRs in media. The highest amounts of all estimated compounds were obtained in biomasses from agar cultures cultivated on medium without PGRs in vitro. In extracts obtained from commercial raw material, gallic acid (max. 261.80 mg / 100 g DW) and quercetin (max. 255.96 mg / 100 g DW) were detected as being the dominant compounds.

ÖZET: Genel olarak Akdeniz bölgesinde yayılış gösteren Cistus L. cinsi, Türkiye'de; C. creticus L., C. parviflorus Lam., C. laurifolius L., C. salviifolius L. ve C. monspeliensis L. olmak üzere beş türle temsil edilmektedir: Bu çalışmada, ülkemizdeki Cistus türlerinin yaprak anatomik yapıları incelenerek, cinsin sistematiğine katkı sağlanması amaçlanmıştır. Çalışmada yaprakların, lamina ve petiyollerden enine ve yüzeysel kesitler alınmış ve Floroglusinol+HCL solsyonu ile boyandıktan sonra Işık mikroskobunda incelenmiş ve fotoğrafları çekilmiştir. Cistus cinsinin yaprak anatomisi Cistaceae familyasının genel karakteristik özelliklerini gösterdiği görülmüştür. Gözlem sonucunda; trikom tipleri, mezofil tabakasındaki lateral damarların abaksiyal epidermise doğru çıkıntı oluşturup oluşturmaması, petiyol lateral kenarlarının bombeli olup olmaması ve stomaların yaprak yüzeyinde bulunup bulunmaması, Cistus türlerinin teşhisini kolaylaştıran önemli karakterler olarak ortaya çıkmıştır. Çalışmanın son kısmında; bu anatomik karakterler esas alınarak bir teşhis anahtarı sunulmuştur.Anahtar kelimeler: Anatomi, Cistaceae, Cistus, Türkiye, yaprak ABSTRACT: The genus Cistus L. (Cistaceae), generally growing in the Mediterranean region, is represented by five species in Turkey: C. creticus L., C. parviflorus Lam., C. laurifolius L., C. salviifolius L. ve C. monspeliensis L. In this study, it is intended to contribute to the systematics of Cistus genus by conducting a comparative anatomical study upon its species distributed in Turkey. The superficial and cross-sections were taken by hand from the lamina and petiyole, and photographs were taken after staining with phloroglucinol + HCl solution and examining under the light microscope. The leaf anatomy of Cistus genus shows the general characteristics of Cistaceae family. As a result of the analysis, it has emerged that facilitate the identification of Cistus species as significant characters, such as the existence / absence of trichomes, types of glandular trichomes, the lateral veins in the mesophyll layer whether to project in the direction of the abaxial epidermis, the lateral edges whether or not cambered, and the presence of stomata on the leaf surface. A diagnostic key has been offered in the last part of the study, based on the anatomical characters.
