Stress physiology of Moringa oleifera under tropospheric ozone enrichment: An ecotype-specific investigation into growth, nonstructural carbohydrates, and polyphenols.

Ozone (O) is an oxidative pollutant that significantly threatens plant development and ecological dynamics. The present study explores the impact of O on Moringa (Moringa oleifera) ecotypes when exposed to ambient and elevated O levels. Elevated O concentrations resulted in significant reductions in total biomass for all ecotypes.

Bioactive Compounds from Genus Potentially Useful for the Development of New Drugs.

The genus Adans. (Crassulaceae) is native to Madagascar and comprises 145 species, being naturalized in the tropics and cultivated worldwide. In addition to having ornamental value, several species are commonly used in popular medicine for the treatment of inflammatory conditions, wounds, gastric ulcers, and other diseases.

Beyond Photoprotection: The Multifarious Roles of Flavonoids in Plant Terrestrialization.

Plants evolved an impressive arsenal of multifunctional specialized metabolites to cope with the novel environmental pressures imposed by the terrestrial habitat when moving from water. Here we examine the multifarious roles of flavonoids in plant terrestrialization. We reason on the environmental drivers, other than the increase in UV-B radiation, that were mostly responsible for the rise of flavonoid metabolism and how flavonoids helped plants in land conquest.

Systemic effects of Tuber melanosporum inoculation in two Corylus avellana genotypes.

Roots of the European hazelnut (Corylus avellana L.), i.e.

Photoprotective Role of Photosynthetic and Non-Photosynthetic Pigments in : Is Their "Antioxidant" Function Prominent in Leaves Exposed to Severe Summer Drought?

Carotenoids and phenylpropanoids play a dual role of limiting and countering photooxidative stress. We hypothesize that their "antioxidant" function is prominent in plants exposed to summer drought, when climatic conditions exacerbate the light stress. To test this, we conducted a field study on , a Mediterranean evergreen shrub, carrying out daily physiological and biochemical analyses in spring and summer.

Phenolic Compounds from Leaves and Flowers of : Potential Skin Cosmetic Applications of an Under-Investigated Species.

The use of plant extracts in skin-care cosmetics is a modern trend due to their richness in polyphenols that act as anti-aging molecules. is a perennial species naturalized in Italy, with beautiful soft pink flowers; its phenolic composition and biological activities have not been studied yet. The aim of this study was to characterize and quantify the phenolics and to evaluate the antioxidant, sun protection factor (SPF), and anti-collagenase activities of the ethanolic extracts of leaves (HL) and flowers (HF).

Optimization of a Green Ultrasound-Assisted Extraction of Different Polyphenols from L. Leaves Using a Response Surface Methodology.

leaves are used in several applications, thanks to their polyphenolic abundance. Thiswork aimed to characterize the polyphenols and to optimize the extraction conditions to shorten the time, decrease the consumption of solvent, and to maximize the yield of different classes of phenolics, which have diverse industrial applications. The variables were optimized by applying a Box-Behnken design.

Wound healing cream formulated with major flavonoid is as effective as the aqueous leaf extract cream in a rat model of excisional wound.

Leaves of are used worldwide for healing skin wounds. This study aimed to develop and compare two creams containing a leaf aqueous extract of (KP; 6%) and its major flavonoid [quercetin 3--α-L-arabinopyranosyl-(1→2)-α-L-rhamnopyranoside] (0.15%).

Differential Distribution of Flavonoids and Phenolic Acids in Leaves of Ecklon & Zeyher (Crassulaceae).

Kalanchoe delagoensis is adapted to intense solar irradiation, drought, and heat, partially due to the presence of phenols, important photo-protective compounds and antioxidants. This study aimed to evaluate the distribution of flavonoids and phenolic acid derivatives throughout the erect-tubular leaves of K. delagoensis.

Optimization of Aqueous Extraction from Kalanchoe pinnata Leaves to Obtain the Highest Content of an Anti-inflammatory Flavonoid using a Response Surface Model.

Introduction: The medicinal plant Kalanchoe pinnata is a phenolic-rich species used worldwide. The reports on its pharmacological uses have increased by 70% in the last 10 years. The leaves of this plant are the main source of an unusual quercetin-diglycosyl flavonoid (QAR, quercetin arabinopyranosyl rhamnopyranoside), which can be easily extracted using water.

Induction of wound-periderm-like tissue in Kalanchoe pinnata (Lam.) Pers. (Crassulaceae) leaves as a defence response to high UV-B radiation levels.

Background And Aims: UV-B radiation can be stressful for plants and cause morphological and biochemical changes. Kalanchoe pinnata is a CAM leaf-succulent species distributed in hot and dry regions, and is rich in flavonoids, which are considered to be protective against UV-B radiation. This study aims to verify if K.

Ultraviolet-B radiation effects on phenolic profile and flavonoid content of Kalanchoe pinnata.

Ultraviolet-B radiation is an important abiotic factor that can stimulate the production of secondary metabolites, including polyphenolic compounds. Kalanchoe pinnata (Crassulaceae) is a medicinal plant popularly used in Brazil for treating wounds and inflammation. This species is rich in phenolic compounds, which could account for some of its biological activities, including antileishmanial, antihypertensive and antibacterial properties.
