Chemical composition and biological activities of Arachis species.
Abstract: Arachis hypogaea; known as the peanut; is native to South America. Peanut seed contains several active components including flavonoids; phenolic acids; phytosterols; alkaloids and stilbenes. Some therapeutic effects have been reported for peanut seed extracts; such as antioxidative; antibacterial; antifungal and anti-inflammatory activities. This paper aims to give an overview of the chemical composition; […]
Quantification of water soluble vitamins in six date palm (Phoenix dactylifera L.) cultivarÂs fruits growing in Dubai; United Arab Emirates; through high performance liquid chromatography
Abstract: In present investigation; a comparative analysis of water soluble vitamins viz.; B1 (thiamine HCl); B2 (riboflavin); B3 (nicotinamide); B5 (pantothenic acid); B6 (pyridoxine HCl); B9 (Folic acid); B12 (Cynocobalamin) was carried out in fruits (immature; semimature and mature) of six date palm (Phoenix dactylifera L.) cultivars (ÂBarheeÂ; ÂKhalasahÂ; ÂMuzatiÂ; ÂShishiÂ; ÂZartÂ; ÂZardaiÂ) growing in […]
Characteristics and pathways of bioactive 4-desmethylsterols; triterpene alcohols and 4a-monomethylsterols; from developing Tunisian cultivars and wild peanut (Arachis hypogaea L.).
ABSTRACT: Seven 4-desmethylsterols; five triterpene alcohols and three 4a-monomethylsterols were identified by GCÂMS during the development of wild peanut; which is Arbi (AraA); and cultivars peanut; which are Trabelsia (AraT) and Chounfakhi (AraC). Our results showed that the maximum level of 4-desmethylsterols (881.07 mg/100 g of oil) was reached at 12 days after flowering (DAF) […]
Consumption of polyunsaturated fatty acids; fish; and nuts and risk of inflammatory disease mortality
BACKGROUND: n-3 (omega-3) Polyunsaturated fatty acids (PUFAs); fish; and nuts can regulate inflammatory processes and responses. OBJECTIVE: We investigated whether dietary intakes of PUFAs [n-3; n-6 (omega-6); and a-linolenic acid]; fish; and nuts were associated with 15-y mortality attributed to noncardiovascular; noncancer inflammatory diseases. DESIGN: The analyses involved 2514 participants aged =49 y at baseline. […]
Characterisation of selected hazelnut cultivars: phenology; growing and yielding capacity; market quality and nutraceutical value
Abstract BACKGROUND: Sixteen hazelnut cultivars growing in the continental climate of Slovenia were analysed over 15 years for their phenology; growth habit; yield potential; susceptibility to hazelnut weevil and the pomological traits and phenolic content of their nuts in order to obtain a complex value of these cultivars for growers; the confectionary industry and consumers. […]
Animal studies of the functional consequences of suboptimal polyunsaturated fatty acid status during pregnancy; lactation and early post-natal life
Abstract: Scores of animal studies demonstrate that seed oils replete with linoleic acid and very low in linolenic acid fed as the exclusive source of fat through pregnancy and lactation result in visual; cognitive; and behavioural deficits in the offspring. Commodity peanut; sunflower; and safflower oils fed to mother rats; guinea pigs; rhesus monkeys; and […]
Micronutrient mineral and folate content of Australian and imported dried fruit products
A selection of Australian and imported fresh and dried fruit products; including sultanas; Sunmuscats; Carina currants; Zante currants; apricots; and prunes; were analyzed for selected minerals (Ca; Mg; Na; S; B; Al; Fe; Mn; Cu; Zn; Mo; and Se); folate and vitamin C; and the capacity of dried fruits for dietary provision of these micronutrients […]
Native Australian fruit polyphenols inhibit COX-2 and iNOS expression in LPS-activated murine macrophages
Purified polyphenolic-rich extracts from four native Australian fruits; Illawarra Plum (Podocarpus elatus Endl.; Podocarpaceae); Kakadu Plum (Terminalia ferdinandiana Exell; Combretaceae); Muntries (Kunzea pomifera F. Muell.; Myrtaceae) and Native Currant (Acrotriche depressa R.Br.; Epacridaceae); were screened for their ability to modulate anti-inflammatory activity in LPS-activated murine macrophages (RAW 264.7). The Kakadu Plum extract inhibited the expression […]
Isolation and identification of ochratoxin A-producing Aspergillus section Nigri strains from California raisins
Aims: To determine incidence and levels of ochratoxin A (OTA) in California raisins; and to isolate and characterize OTA-producing fungi from Forty California raisin vineyard populations. Methods and Results: raisin clusters sampled from four California vineyards in the San Joaquin Valley were analyzed for OTA content using immunoaffinity and HPLC methods. OTA was detected in […]
Preliminary characterization of food tablets from date (Phoenix dactylifera L.) and spirulina (Spirulina sp.) powders.
Abstract: In this work; some physical properties (hardness; friability; disintegration time and erosion) of food tablets containing various food powders obtained from dates (Phoenix dactylifera L.); spirulina (Spirulina sp.) and oranges (juice and zest) were investigated. Also; experimental data related to the release kinetic of phycocyanin (antioxidant substance of spirulina) into different liquid mediums; correctly […]
