The phenolic composition of Coffea leaves has barely been studied, and therefore this study conducts the first detailed survey, focusing on mangiferin hydroxycinnamic acid esters (HCEs). Using HPLC, including a new technique allowing quantification feruloylquinic together with mangiferin, histochemical methods, content tissue localization were compared in fruits C. pseudozanguebariae, arabica canephora. HCE was evaluated for 23 species native to Africa or Madagascar. various statistical data...
Summary UV ‐ B radiation damage in leaves is prevented by epidermal ‐screening compounds that can be modulated throughout ontogeny. In epiphytic orchids, roots need to protected against because they photosynthesize, sometimes even replacing the leaves. How orchid roots, which are covered a dead tissue called velamen, avoid currently unknown. We tested for protective function of velamen using gene expression analyses, mass spectrometry, histochemistry, and chlorophyll fluorescence P...
ABSTRACT Chlorophyll (Chl) and epidermal polyphenol (EPhen) contents were estimated in vivo using two optical leaf‐clips, SPAD‐502 Dualex, respectively. The area‐based measurements transformed into mass‐based data by taking account the leaf dry mass per area (LMA). Measurements performed on forest trees saplings grown under controlled conditions. While LMA increased with irradiance along a vertical transect beech canopy or different increasing levels, EPhen (EPhen m ) increased, whereas Chl...
The understorey origin of coffee trees and the strong plasticity Coffea arabica leaves in relation to contrasting light environments have been largely shown. adaptability changes was tested under controlled conditions by increasing illumination rate on C. var. Naryelis seedlings acclimated low observing leaf responses at three different developmental stages (juvenile, growing mature). Only mature proved capable adapting new conditions. In these leaves, major mechanisms were found contribute...
Mesoporous silica nanoparticles (MSNs) were covalently coated with antioxidant molecules, namely, caffeic acid (MSN-CAF) or rutin (MSN-RUT), in order to diminish the impact of oxidative stress induced after transfection into cells, thus generating safer carriers used for either drug delivery other applications. Two cellular models involved entry NPs body this purpose: intestinal Caco-2 and epidermal HaCaT cell lines. Rutin gave best results terms capacities preservation during coupling...
Analysis of the fast kinetics induction curve maximal fluorescence represents a relatively recent development for chlorophyll (ChlF) measurements. The parameters so-called JIP-test are exploited by an increasingly large community users to assess plant stress and its consequences. We provide here evidence that these capable distinguish between stresses different natures or intensities, stressed plants genetic background at developmental stages time stress. It is however important keep in mind...
Carbon partitioning is important for understanding root development but little known about its regulation. Existing models suggest that controlled by the potential sink strength. They cannot, however, simulate hierarchical uptake other than using absolute priorities. Moreover, they cannot explain changes in photoassimilate result from photosynthesis. In this paper we present a model of phloem sieve circulation, based on Minchin et al . ( Journal Experimental Botany44 : 947–955, 1993). The...
The inhibition of recombinant CpLIP2 lipase/acyltransferase from Candida parapsiolosis was considered a key model for novel antifungal drug discovery and potential therapeutic target candidiasis. Lipases have identified recently as potent virulence factors in C. parapsilosis some other yeasts. effects orlistat four flavonols (galangin, kaempferol, quercetin myricetin) characterized by an increasing degree hydroxylation B-ring, were investigated using ethyl oleate hydrolysis the reaction....
In the present study, we obtained a dried burdock root extract (DBRE) rich in caffeoylquinic acids derivatives. We performed chemical characterization of DBRE and explored its antihyperglycemic potential both vitro vivo experiments. Chemical analysis using LC-MS GC-MS revealed presence great majority dicaffeoylquinic acid derivatives (75.4%) which 1,5-di-O-caffeoyl-4-O-maloylquinic represents 44% extract. experiments, is able to increase glucose uptake cultured L6 myocytes decrease...
Root system architecture partially results from meristem activities, which themselves depend on endogenous and environmental factors, such as O2 depletion. In this study, respiration growth was measured in the root systems of three Prunus persica (L.) Batsch seedlings. The spatial distribution within described, relationship between rates radii analysed, using a model radial diffusion consumption root. Histological observations were also used to help interpret results. Respiration linearly...
Metabolic syndrome (METS) is a complex disorder that predisposes an affected person to increased risk of diabetes and cardiovascular disease. Bitter Asteraceae plants contain several compounds active against METS can be used as alternative preventive therapy. Our previous work showed natural chicory extract (NCRAE) containing chicoric acid (CRA) chlorogenic (CGA) in molar ratio 70/30 exhibited antioxidant, insulin sensitization anti-hyperglycemic effect. The present study was designed...
The prevalence of metabolic syndrome (METS) directly correlates with the obesity, and it is associated several other risk factors. Among them, chronic inflammation, oxidative stress insulin resistance might be reduced in order to delay progression METS. first management METS involves physical exercises a suitable diet. Many Asteraceae are plants commonly consumed. bitter known for their health effect traditionally used as drinks. Their particularly rich contents sesquiterpene lactones...

Mediterranean forests represent critical areas that are increasingly affected by the frequency of droughts and fires, anthropic activities land use changes. Optical remote sensing data give access to several essential biodiversity variables, such as species traits (related vegetation biophysical biochemical composition), which can help better understand structure functioning these forests. However, their reliability highly depends on scale observation spectral configuration sensor. Thus,...
