kingdom, is believed to play a preventive role in the development of certain diseases associated with free radical-induced damage in the body. The high sensitivity of flavonoids to react with free radicals makes them pharmacological effective. Flavonoids and their ability to inactivate superoxide anion radicals (O2· ) have been studied for about a decade. Flavonoids are most likely to react wit...

Numerous studies have documented that in cancer therapy flavonoids extracted from traditional Chinese medicine have anti-tumor activity or can enhance efficiency of chemotherapy in combination with chemotherapeutics. Thus, an awareness of flavonoids is needed by physicians and medical researchers. This review provides evidence about anti-hepatocellular carcinoma activity of flavonoids. First, a...

• Climate and land use change were used to model habitat suitability of Rhododendron. Land climate interaction may the invasiveness South-western north-eastern Wales experience R. ponticum invasion by 2030. The study demonstrates significance using policy-driven projections. Global drivers such as changes are known interact in their effects on biodiversity. impact these global biodiversity is i...

background: although several studies have investigated the association between ovarian cancer risk and nonisoflavone flavonoids intake, these findings are inconsistent. this systematic review of published epidemiological studies was conducted to summarize and clarify the evidence on the association between ovarian cancer incidence and nonisoflavone flavonoids intake. materials and methods: pubm...

Flavonoid compound was isolated from Crinum amabile Donn. leaves. The separation of flavonoids carried out by using chromatographic techniques to purify CH2Cl2 extract Column chromatography with silica gel and sephadex as stationary phases, thin-layer chromatography, preparative were the used in this research. pure obtained form white-yellow solid Rf value is 0.44. Compound identification 1H-NM...

Lawsonia inermis L., or henna leaves, are usually used to treat wounds on the skin. contain naphthoquinones, flavonoids, tannins, and saponins. The antibacterial activity of L. leaf extract in various solvents has been extensively studied. However, which component is responsible for still unknown. This study was intended investigate effect fractions against Staphylococcus aureus discover chemic...

Plasticity in crown architecture, contributing to leaf arrangement within crown, is an important feature for whole plant carbon assimilation and survival. In this study, I examined the plasticity in crown architecture to light condition and developmental stage by the changes in shoot production. Rhododendron reticulatum expands crown with orthotropic growth in monopodial branching in young stag...

What resources should be committed to the control of invasive species? This study is based on a survey of nature conservation and forestry authorities, wildlife trusts and private landowners which investigated the extent of the ecological and economic impacts of the invasive non-native plant Rhododendron ponticum in the British Isles. There are data on 52,000 ha of land affected by R. ponticum,...
