Agroforestry by-products have gained rising attention in recent years as they represent inexpensive and abundant raw materials that are a source of added-value chemicals, e.g., for food pharmaceutical applications, well bioenergy generation. Pinus pinaster Ait. bark extracts consumed worldwide their cardiovascular benefits, whilst the health potential pinea L. has not yet been deeply exploited....

In the course of screening for antioxidant compounds by measuring the radical scavenging effect on DPPH (1,1-diphenyl2-picrylhydrazyl), a total extract of the twigs of Vitex rotundifolia (Verbenaceae) was found to show potent antioxidant activity. Subsequent activity-guided fractionation of the methanolic extract led to the isolation of three iridoid compounds, 10-O-vanilloylaucubin (1), 10-O-p...

Western flower thrips (Frankliniella occidentalis) has become a key insect pest of agricultural and horticultural crops worldwide. Little is known about host plant resistance to thrips. In this study, we investigated thrips resistance in chrysanthemum (Dendranthema grandiflora). We identified thrips-resistant chrysanthemums applying bioassays. Subsequently, nuclear magnetic resonance (NMR)-base...

Abstract Moringa oleifera seed and leaf are used traditionally for the treatment of various health problems (among others, hypertension, scrapes, skin infection, diabetes, genitourinary illnesses), to boost immune system, as well act a contraceptive. In this study, antibacterial activity M. extracts on three-gram negative bacteria was investigated, phytochemical analysis association with active...

In the present study, a new complex Cr(III)-quinic was synthesized. The new species was characterized by elemental analysis, spectroscopic, structural, thermal, EPR and magnetic susceptibility studies. Detailed aqueous speciation studies in the Cr(III)-quinic system suggest the presence of a number of species with distinct structural properties related to the ones encountered in the synthetic c...

The prevalence of obesity is increasing globally, and obesity is a major risk factor for type 2 diabetes and cardiovascular disease. We investigated the effects of coffee polyphenols (CPP), which are abundant in coffee and consumed worldwide, on diet-induced body fat accumulation. C57BL/6J mice were fed either a control diet, a high-fat diet, or a high-fat diet supplemented with 0.5 to 1.0% CPP...

This research revalues broccoli stalk by-product as a novel fermented health food, using its autochthonous microbiota. Broccoli slices were packed into glass jars, brine was added (6% w/v), and two dressings studied: garlic, mustard seeds. No dressing used control. Natural fermentation carried out at 25 °C for 6 days followed by further storage 4 °C. The identification of individual glucosinola...

The qa-1 regulatory region controls the expression of the three structural genes required for the early reactions in quinic acid catabolism in Neurospora crassa. Genetic analysis previously identified two types of noninducible qa-1 mutants, qa-1S and qa-1F, which mapped in separate non-overlapping regions. These mutations were originally interpreted as defining separate domains of a single regu...

Metabolic profiling was used to investigate the molecular phenotypes of a transgenic Populus tremula x P. alba hybrid expressing the nahG transgene, a bacterial gene encoding salicylate hydroxylase that converts salicylic acid to catechol. Despite the efficacy of this transgenic approach to reduce salicylic acid levels in other model systems and thereby elucidate roles for salicylic acid in pla...
