The Opuntia ficus indica (L.) (OFI) is used as a nutritional and pharmaceutical agent in various dietary and value added products. This study underlines the possible use of native prickly pear cladode powder as a functional ingredient for health-promoting food production. To summarise, chemical characterization of polyphenols, minerals and soluble dietary fibre was performed; furthermore, the antioxidant activity and bioaccessibility of polyphenols and minerals were assessed. Eleven compounds between phenolic acids and flavonoids were identified, with piscidic acid and isorhamnetin derivatives being the most abundant. Opuntia’s dietary fibre was mainly constituted of mucilage and pectin, and was composed of arabinose, galactose, glucose, mannose, rhamnose, and xylose sugars. The polyphenols’ bioaccessibility was very high: piscidic acid at 200%, eucomic and ferulic acids >110% and flavonoids from 89% to 100%. The prickly pear cladode powder is also a source of minerals, as cations (calcium, sodium, potassium and magnesium) and anions (sulphate and chloride), with high magnesium bioaccessibilty (93%). OFI powder showed good capacity of radical scavenging measured by DPPH and ABTS methods, with 740 and 775 μmol Trolox/100 g OFI, respectively. Finally, the presented results allow the consideration of this natural product as a source of several essential nutrients, with a possible use in the food industry as a functional ingredient.

Hydrodistillation of the fresh leaves of E.grandis×E.urophylla hybrids and pure species E.grandis, E.urophylla, E.pellita, E.camaldulensis, E. dunni, and E.saligna collected from the trees grown in Guangxi Huangmian Forest (China), afforded essential oils in yields varying from 0.24±0.15% to 5.36±0.28%, according to the species. Analysis by GC (FID) and GC/MS allowed the identification of 67 compounds, representing 82.55% to 91.03% of the total oil composition. The dominant compounds were 1,8-cineole in E.saligna, E.urophylla, E.grandis×E.urophylla, E.grandis, E.pellita and E. dunni (67.48, 57.12, 48.21, 23.64, 20.34, 20.22%), p-Cymene in E.camaldulensis,E. dunni and E.grandis(21.32, 14.74, 13.38%), α-pinene in E.grandis and E.grandis×E.urophylla (21.77, 15.55%), α-terpinene in E. dunni and E.grandis (17.96, 9.35%), α-terpineol in E.pellita and E.saligna (19.24,11.54%), respectively. Hierarchical Cluster Analysis separated the characterized essential oils into two groups, each constituting a chemotype. E.grandis×E.urophylla and E.urophylla were classified in the same group, while E.grandis in the other.

This study aimed to chemically characterize the bark extracts from three tree species: Anacardium occidentale L., Ziziphus joazeiro Mart. and Mimosa caesalpiniaefolia Benth., in addition to obtaining the soluble extract content in water, alcohol and hexane from the bark of these species. The bark was collected from branches of the three species and subsequently pre-dried and milled. The extract content was then determined using the Sohxlet method aiming to quantify the total extractives in the samples, and determine the extract content soluble in water, ethyl alcohol and hexane. The extracts were further analyzed by Near Infrared Spectroscopy (NIRS) analysis to determine their chemical composition. The extract contents in the three species behaved in a similar way, with hexane being the solvent which extracted more compounds and juazeiro the species that displayed the highest total extract content. With the chemical characterization of the extracts, it was possible to identify the presence of functional groups characteristic of carbohydrates and proteins in the aqueous extracts; the presence of characteristic hydroxyl group, for example in alcohols, aldehydes, ketones and ethers in the ethanolic extracts; and the presence of fatty acids and aromatic compounds (essential oils) in hexanolic extracts. The essential oils were the compounds which presented larger quantities, and can be exploited by the pharmaco-chemical industry.
