cistus laurifolius/抗氧化剂

Mechanisms of drought stress resistance were studied in Cistus clusii Dunal and Cistus albidus L., two native Mediterranean shrubs that can withstand severe summer drought. While water deficit, solar radiation and temperature increased from winter to summer in the field, C. clusii and C. albidus

The hypothesis that anthocyanins in red leaves may be potential in vivo antioxidants whose efficiency is linked to their proximity with the oxy-radical source was tested. Advantage was taken of intra-individual and intra-species variations in the anthocyanic trait and green and red leaves on the

The Mediterranean shrub Cistus ladanifer grows naturally in São Domingos (Portugal), an abandoned copper mine. High levels of trace elements in plants can generate oxidative stress increasing the activity of antioxidant enzymes. The aim of this work was to evaluate and compare As, Cu, Pb and Zn

The genus Cistus includes many typical species of Mediterranean flora; Cistus species are used as antidiarrhetics, as general remedies for treatment of various skin diseases in folk medicine and as anti-inflammatory agents. These species contain flavonoids that are considered to be chain-breaking

The chemical composition of three rockrose Cistus species, Cistus monspeliensis, Cistus libanotis and Cistus villosus, collected in Tunisia, was studied by HPTLC, focusing on the terpenes and phenols constituents. Diterpenes of Cistus are important as the main constituents of the leaf sticky

Cistus heterophyllus subsp. carthaginensis is an endemic and endangered species from the SE Mediterranean coastal region of Spain. Within the framework of the efforts aiming to species conservation, in vitro culture techniques could be of interest. The aim of this study was to evaluate the

As Cistus laurifolius has been used traditionally to treat inflammatory and rheumatic disorders, its leaves were tested for prostaglandin (PG) inhibitory and antioxidant activities. The leaf extract showed both activities, i.e., inhibitory effect at 300 microg/ml on PGE1- and E2-induced contractions

Skin is constantly exposed to harmful environmental factors, causing photo-oxidative stress in cells and leading to the development of health and aesthetic problems. Multifunctional ingredients of everyday skincare products, possessing antioxidant, UV-protecting, anti-hyperpigmentation, and skin

Cistus genus (Cistaceae) comprises several medicinal plants used in traditional medicines to treat several pathological conditions including hyperglycemia. These include Cistus salviifolius L. (CS) and Cistus monspeliensis L. (CM), still not fully explored as a source of metabolites with therapeutic

Mediterranean plants have evolved a complex antioxidant defense system to cope with summer drought. Flavonoids, and particularly flavanols and flavonols, are potent in vitro antioxidants, but their in vivo significance within the complex network of antioxidant defenses remains unclear, especially in

The enzymatic hydrolysates from pollen Cistus ladaniferus were digested and prepared using three kinds of enzymes (pepsin, trypsin, and papain) and the antioxidative properties were investigated. The yields, total phenolic contents, and protein contents of these hydrolysates were as follows: yields

The purpose of the present study is to survey the extraction conditions and explore the antioxidant potential of the wild herb Cistus incanus, which is non-traditional in Bulgarian ethnomedicine and widespread in the Strandja Mountain. The influence of the extraction time (0-500 min) and solvent

The ageing process in living organisms is characterised by the accumulation of several deleterious changes occurring in cells and tissues. The increase of reactive oxygen species with the advancement of age is responsible for the oxidative damage to proteins, lipids and DNA, enhancing the risk of

Polyphenol rich extracts obtained from cistus herb (Cistus incanus L.) and pomegranate peel (Punica granatum L.) exhibited significant antioxidant activity in V79 cell culture (Chinese hamster lung fibroblasts) -cistus extract reduced intracellular content of reactive oxygen species (ROS) by 30-40%
