High impact information on Cistus

• We simultaneously analyzed lipid oxidation, photosynthesis, chlorophyll content, de-epoxidation state of the xanthophyll cycle, and levels of chloroplastic antioxidant defenses such as beta-carotene and alpha-tocopherol in leaves of the same age in 1-, 3- and 7-year-old Cistus clusii Dunal plants growing under Mediterranean field conditions [1].
• The method was validated and applied to the determination of catechin and gallocatechin in lyophilized extracts of Cistus incanus and Cistus monspeliensis [2].
• Essential oils and hexane extracts from Cistus monspeliensis L. leaves and fruits were analysed by GC-MS [3].
• Fractionation of the resin Ladano from Cistus creticus subsp. creticus and susceptibility testing using the chromatographic fractions showed that its antistaphylococcal activity was mainly due to the diterpene sclareol [4].
• Antioxidative ability in a linoleic acid oxidation system and scavenging abilities against active oxygen species of enzymatic hydrolysates from pollen Cistus ladaniferus [5].

Biological context of Cistus

• Flow cytometry, using propidium iodide and 4',6-diamidano-2-phenylindole staining, was used to estimate the nuclear DNA content (2C) and the proportion of A-T base pairs in 16 species of the Mediterranean genus Cistus [6].

Associations of Cistus with chemical compounds

• In an attempt to identify the structure of a sesquiterpene from Cistus creticus ssp. creticus proposed in the literature as 1,1,4a,6-tetramethyl-5-methylene-1,2,3,4,4alpha,5,8,8alpha-octahydronaphthalene, the synthesis of its cis isomer 2 was carried out in 11 steps and 9.5% yield [7].
• 2,2,6-Trimethylcyclohexanone and ethyl dihydrocinnamate, known sensorial descriptors of rock-rose (Cistus ladaniferus) aroma, are reported as minor constituents of young fortified wines from the Douro Demarcated region (vintage 1997) for the first time [8].
• Prodelphinidin trimers and characterization of a proanthocyanidin oligomer from Cistus albidus [9].
• Two new natural prodelphinidin trimers have been isolated from the air-dried herb of Cistus albidus, epigallocatechin-(4beta --> 8)-gallocatechin-(4alpha --> 8)-catechin and epigallocatechin-(4beta --> 8)-gallocatechin-(4alpha --> 8)-gallocatechin in addition to catechin, gallocatechin and thirteen known proanthocyanidins [9].
• Effect of Cistus laurifolius L. leaf extracts and flavonoids on acetaminophen-induced hepatotoxicity in mice [10].

Gene context of Cistus

• Nevertheless, the A50 environment (dominated by Quercus suber) showed the best soil properties, whilst the A25 environment with dense cover of Cistus monspeliensis and Calicotome espinosa seemed to cause a worsening effect on the soil's physical and chemical properties [11].
• Seven plants containing 5 species of Cistus genus exhibited a potent inhibition of h-AR [12].
• Among them, the veterinary use of Cistus incanus, Colutea arborescens, Daphne laureola, and Erigeron acer is reported for the first time [13].
