The present work was carried out to evaluate the effects of irrigation with two different municipal wastewaters (secondary-treated wastewater (SW) and tertiary-treated wastewater (TW)) compared to freshwater (FW) on main qualitative parameters of three different classes of globe artichoke (main, secondary, and processing heads). The experimental trial was conducted in Southern Italy (Apulia region) for two cropping cycles (GS1 and GS2) using ‘Violetto di Provenza’ as cultivar. The artichoke heads were analyzed for proximate composition (dry matter, total sugar, total fat, ash, and total protein), percentage of edible part, mineral profile (sodium, potassium, magnesium, calcium, copper, iron, nickel, zinc, chloride, nitrate, phosphate, and sulphate) and polyphenolic acids content (caffeoylquinic acids and flavones). Both SW and TW treatments caused an increase of the percentage of the edible part, head protein contents, and mineral elements of the main and processing heads. Moreover, SW statistically increased the caffeoylquinic acid derivatives and the trans-ferulic acid content, while both SW and TW the flavones content. Finally, according to the multivariate analysis adopted, in our experimental conditions, the mineral component of the heads, such as chloride, potassium, copper, and zinc content, had a greater weight in the separation of FW, SW, and TW. On the other hand, the polyphenolic 5-O-caffeoylquinic acid, trans-ferulic acid, and 1,5-di-O-caffeoylquinic acid had a greater weight in the separation of the head class groups (main, secondary, and processing). Moreover, the trans-ferulic acid content of the heads was related both to the irrigation water type and to the different head classes.

Description of the subject. Maize (Zea mays L.) is a major staple food providing nutrients for humans and animals worldwide. In Sub-Saharan Africa, maize is stored to ensure food resource availability throughout the year. However, stored-product pests such as the maize weevil, Sitophilus zeamais (Motsch.) (Coleoptera; Curculionidae) can cause huge grain losses. Objectives. This study aimed to assess the oviposition preference of Sitophilus zeamais over maize varieties commonly cultivated in Senegal and the effect of grain morphophysical and biochemical characteristics on their susceptibility to the maize weevil. Method. Twenty-five S. zeamais pairs (M/F) were placed in the center of an arena at equal distance of small heaps of maize grains (30 g) from nine maize varieties. Adult abundance, damaged grains, grain weight loss, and progeny were confronted to grain characteristics (phenolics and ferulic acid content, hardness, brightness, color and size of grains). Results. Susceptibility to the maize weevil varied significantly among maize varieties. Synth-9243 was the most susceptible variety with greatest damaged grains (10.5 ± 2.3%), grain weight loss (2.3 ± 0.6%), and progeny (17.3 ± 3.8 adults). The least susceptible varieties were Across-Pool, SWAN, Obatampa, and Tzee-Yellow. Grain characteristics such as phenolics and ferulic acid content were negatively related to susceptibility, but other constituents may have antixenosis or antibiosis effects. In addition, grain brightness may also have a visual effect deterring oviposition. Conclusions. The most repellent and less favorable varieties for S. zeamais were Tzee-Yellow, Across-Pool, Obatampa and SWAN, that presented high content of phenolics and ferulic acid, hardness and brightness of grains.

Abstract The aim of the present study was to determine and compare the fatty acids, lipid soluble vitamins, sterols, phenolics, and antioxidant capacities of three endemic Salvia L. taxa (S. euphratica var. Montbret & Aucher ex Bentham leiocalycina (Rech. Fil.) Hedge, S. euphratica var. Montbret & Aucher ex Bentham euphratica (Rech. Fil.) Hedge and S. pseudoeuphratica Rech.Fil.) and to evaluate these results systematically. The fatty acid compositions were determined by using gas chromatography, while the lipid soluble vitamins, sterols, and phenolics were determined by using HPLC. Also, the antioxidant capacities of three Salvia taxa were measured in vitro. Palmitic acid was found as major saturated fatty acid while oleic acid, linoleic acid, α-linolenic acid, and erucic acid were found as major unsaturated fatty acids in the present study. It was found that S. euphratica var. euphratica had lower palmitic acid (8.94 ± 0.71%), total saturated fatty acid (19.16 ± 0.15%), and higher unsaturated fatty acid content (82.08 ± 0.52%) than other studied taxa. Furthermore, it was shown that S. euphratica var. euphratica had different 18.3/18:2 (0.36) unsaturated/saturated fatty acid (4.28) ratios. However, this study demonstrated that Salvia taxa had low lipid soluble vitamins, sterol contents. On the other hand, it was shown that Salvia taxa had similar catechin (509.2 ± 4.21 µg/g and 552.2 ± 9.21 µg/g) and vanillic acid amounts (351.2 ± 2.17 µg/g and 396.8 ± 4.1 µg/g) in this study. And also, it was found that Salvia taxa had high rosmarinic acid content while S. euphratica var. leiocalycina had the highest rosmarinic acid content (1480 ± 7.57 µg/g). On the other hand, it was shown that the two ferulic acid contents of S. euphratica varieties were higher (1175 ±/5.21 µgmg-1740.2 ± 4.82 µg/mg) than the ferulic acid content of S. pseudoeuphratica of which was the lowest (19.2 ± 0.97 µg/mg). The present results suggested that the biochemical results guided the morphological studies, and Salvia taxa have a potent antioxidant capacity.
