Capparis spinosa shows strong resistance to the adverse Mediterranean conditions and it has nutritional and medicinal value. The aim of this
study was to evaluate the contents of total phenolic compounds, rutin, tocopherols, carotenoids and vitamin C in leaves and
flower buds of C. spinosa from different locations in Tunisia. Results showed the richness of caper with these compounds, especially phenolic compounds.
Interestingly, it was also found the presence of both α- and γ-tocopherol in buds. Moreover, C. spinosa contained an appreciable level of vitamin C. The significant amounts of these antioxidants confirm the nutritional and medicinal
value of caper. 相似文献

Cucumis setosus Cogn. is a rare, endemic, wild gathered or semi-domesticated vegetable restricted to Maharashtra state and border districts of adjoining states in India. Herbarium and literature survey shows that it is poorly collected and inadequately studied. Morphological characters, basic chromosome number and crossability barriers indicate that Cucumis setosus is a valid species, distinct from C. sativus and endemic to western India. Its morphology, basic cytology, crossability relationship with other Cucumis species, taxonomy, distribution, ecology, conservation, economic importance and viability under cultivation are discussed. Besides, a key to distinguish it from C. sativus var. hardwickii (wild and feral form of C. sativus) and other species having sympatric distribution in the area is also presented. Absence of bitter principle in the fruits makes it a potential germplasm for melon and cucumber improvement as well as direct domestication as a future crop. 相似文献

Species that belong to the genus Triticum L. and the genetically related Aegilops L. genus are important genetic and economic resources because they have an evolutionary relationship with the two main agricultural
crops T. aestivum (bread wheat) and T. durum (durum wheat). Therefore, it is important to understand the genetic relationships among the cultivated wheat species and
their wild relatives. The latter have a great role in the improvement of cultivated wheat. Molecular markers are the best
choice and most reliable means to study these relationships accurately. In this study, we compared the efficiency of the biochemical
methods A–PAGE and SDS–PAGE on seed storage proteins and the molecular methods RAPDs and ISSRs to explore the genetic relationships
among seven species of Triticum and 20 Aegilops species. Three phylogenetic trees obtained in this study were compared with available classifications and phylogenetic trees
constructed earlier for these species. It was noted that the tree based on ISSRs data was the most congruent with those classification
and trees. This may be attributed to the fact that ISSRs is more specific, and therefore more reliable. This study is the
first to study genetic relationships among all species studied here using biochemical and molecular techniques. 相似文献

Inhibition of low-density lipoprotein oxidation and up-regulation of low-density lipoprotein receptor in HepG2 cells by tropical plant extracts 总被引：2，自引：0，他引：2

Twelve edible plant extracts rich in polyphenols were screened for their potential to inhibit oxidation of low-density lipoprotein (LDL) in vitro and to modulate LDL receptor (LDLr) activity in cultured HepG2 cells. The antioxidant activity (inhibition of LDL oxidation) was determined by measuring the formation of conjugated dienes (lag time) and thiobarbituric acid reagent substances (TBARS). Betel leaf (94%), cashew shoot (63%), Japanese mint (52%), semambu leaf (50%), palm frond (41%), sweet potato shoot, chilli fruit, papaya shoot, roselle calyx, and maman showed significantly increased lag time (>55 min, P < 0.05) and inhibition of TBARS formation (P < 0.05) compared to control. LDLr was significantly up-regulated (P < 0.05) by Japanese mint (67%), semambu (51%), cashew (50%), and noni (49%). Except for noni and betel leaf, most plant extracts studied demonstrated a positive association between antioxidant activity and the ability to up-regulate LDL receptor. Findings suggest that reported protective actions of plant polyphenols on lipoprotein metabolism might be exerted at different biochemical mechanisms. 相似文献

The date palm, Phoenix dactylifera, is a palm extensively cultivated for its edible fruit. The chemical composition and the water content of ten Tunisian date varieties were determined. For all analysis, the Deglet Nour variety was taken as reference. Compositional analysis showed that the littoral varieties were very rich in reducing sugars (26 to 51%) than Deglet Nour which was rich in sucrose (54%). The relative results of the moisture content showed that the littoral varieties were classified as soft dates. The vitamin C analysis showed that the littoral varieties were very rich in this compound (24 to 46 mg/100 g) than Deglet Nour (1.12 mg/100 g). The mineral analysis showed that the littoral dates were relatively rich in potassium (283 to 733 mg/100 g) and presented a weak content in sodium (0.06 to 0.09 mg/100 g). 相似文献

This study reports on the polybrominated diphenyl ether (PBDE) atmospheric dynamics in the dense urban environment of downtown
Paris (France). Eight PBDE congeners (BDE-28, BDE-47, BDE-100, BDE-99, BDE-154, BDE-153, BDE-183 and BDE-209) were simultaneously
analysed in bulk and wet atmospheric deposition, as well as in ambient air (gaseous/particulate phases), twice a month over
a 12-month period (May 2008–May 2009). The total air concentration of Σ 8PBDEs ranged between 12 and 185 pg m−3, and the seasonal variations of PBDE levels were controlled by air temperature (except for BDE-209). Regarding bulk deposition,
Σ 8PBDE flux was in the range 5–94 ng m−2 day−1, and it was positively correlated with atmospheric particulate phase PBDE concentrations. Meanwhile, the measured wet deposition
flux of Σ 8PBDE ranged between 2 and 24 ng m−2 day−1, and its median contribution to bulk deposition was 39% only, which highlights the importance of dry deposition. 相似文献

In Tunisia, on‐site co‐composting of oil mill waste would overcome environmental issues and valorize renewable resources. The authors' goal was to determine the physic‐chemical and microbiological properties and nutrient supply characteristics of mixed oil mill waste and green waste compost. Two piles of the same raw materials (2/3 oil mill waste–1/3 green waste, w/w) were moistened with two kinds of water: treated urban wastewater (A1) and tap water (A2). Results showed the following: (i) produced compost decreased in C/N from 32 to 12.30?±?0.89 (A1) and 11?±?0.89 (A2); (ii) major elements (P and K) were within acceptable limits; (iii) A1 and A2 had potentially lower heavy metal contents than the limits established by the second draft of the Biological Treatment of Biowaste of the European Commission and microbial load values below the limit N FU 44‐051 values; (iv) A1 and A2 had, respectively, 93 and 89.67% as germination index Gl values, which confirmed the composts' maturity and safety; (v) for both composts, A1 and A2, culture potting made up of half compost and half soil revealed the highest bean leaves' number; and (vi) the less richness in minerals and organic compounds of A2 compared to A1 gave better germination results for white wheat and bean leaves' number for A2. Even moistened with treated urban waste water, oil mill wastes proved to be very interesting for co‐composting with green waste. 相似文献

Biodegradability Improvement of Sulfamethazine Solutions by Means of an electro-Fenton Process 总被引：1，自引：0，他引：1

The main objective of this study was to examine the effect of an electro-Fenton pretreatment on the biodegradability of sulfamethazine-polluted solutions. The aim of the pretreatment was only to degrade this molecule in order to increase the biodegradability of the effluent and therefore allow a subsequent biological treatment. Preliminary tests showed the absence of biodegradability of the target compound. The degradation of sulfamethazine by electro-Fenton process was then examined using a carbon felt cathode and a platinum anode in an electrochemical reactor containing 1?L of solution. The influence of some experimental parameters such as initial concentration, temperature and current intensity on the degradation by electro-Fenton step has been investigated. In addition, the biodegradability of the solution after electrochemical pretreatment was examined and showed a Biological Oxygen Demand (BOD5) on Chemical Oxygen Demand (COD) ratio above the limit of biodegradability, namely 0.4, for several experimental conditions. The feasibility of coupling an electro-Fenton pretreatment with a biological degradation of by-products in order to mineralize polluted solutions of sulfamethazine was confirmed. 相似文献
