Supercritical CO2 extracts from Acacia dealbata flowers
The Journal of Supercritical Fluids, 2021Abstract Supercritical CO2 was used for the production of extracts from Acacia dealbata flowers. Pressures from 10 to 35 MPa and temperatures from 35° to 55°C were studied to assess their influence on the yield, antiradical properties and composition of the volatiles. The use of ethanol as modifier was also evaluated.

Triterpenes fromAcacia Dealbata
Natural Product Letters, 1996Abstract From the leaves, flowers and seeds of A. dealbata four lupene type triterpenes, lupenone, lupeol, lupenyl palpimate and lupenyl cinnamate, not previously reported in this genus, have been isolated. Their structures were established by spectroscopic means and by comparison with literature references.

Bioactive properties of Acacia dealbata flowers extracts
Waste and Biomass Valorization, 2019Floral waste has been considered one of the major concerns, even for those that may have industrial applications, such as dyes or perfumes. In the present study, the possibility of using Acacia dealbata flowers’ extracts and respective fractions as bioactive agents was explored in vitro systems. A.

An evaluation of the potential of Acacia dealbata as raw material for bioethanol production
Bioresource Technology, 2011In this work, the potential of Acacia dealbata as raw material for ethanol production was evaluated, as well as its composition with regard to cellulose, hemicelluloses, lignin, extractives and ash. The tree samples were subjected to several dilute acid pretreatments using a combined severity parameter ranging from 0.7 to 3.7.

The gum exudates from acacia dealbata and acacia sieberana: corrections to previous analytical data
Carbohydrate Research, 1973Abstract In the light of the analytical data acquired for the gum exudates from a greatly increased number of Acacia species in recent years, the data published for A . sieberana gum in 1939, and for A . dealbata gum in 1966, differ considerably, in several respects, from the range of values established for some closely related species.

The effect of soil legacy on competition and invasion by Acacia dealbata Link
Plant Ecology, 2013Plant–soil feedbacks can exacerbate competition between invasive and native species, although the net effect of the interaction between soil biota and competition is likely to be species-specific. Very few studies have addressed the combined effect of soil and competition on plant performance and invasion by exotic woody species.
