The present study was designed to characterize the polyphenols isolated from acacia mearnsii bark crude extract(B) and fractions(B1-B7) obtained by high-speed counter-current chromatography(HSCCC) and evaluate their anti-inflammatory and carbolytic enzymes(α-glucosidase and α-amylase) inhibitory activities. Fractions B4, B5, B6, B7(total phenolics 850.3, 983.0, 843.9, and 572.5 mg·g^(-1)), respectively; proanthocyanidins 75.7, 90.5, 95.0, and 44.8 mg·g^(-1)), respectively) showed significant activities against reactive oxygen species(ROS), nitric oxide(NO) production, and expression of pro-inflammatory genes interleukin-1β(IL-1β) and inducible nitric oxide synthase(iNOS) in a lipopolysaccharide(LPS)-stimulated mouse macrophage cell line RAW 264.7. All the extracts suppressed α-glucosidase and α-amylase activities, two primary enzymes responsible for carbohydrate digestion. A. mearnsii bark samples possessed significantly stronger inhibitory effects against α-glucosidase enzyme(IC_(50) of 0.4-1.4 μg·mL^(-1)) than the pharmaceutical acarbose(IC_(50) 141.8 μg·mL^(-1))). B6 and B7(IC_(50) 17.6 and 11.7 μg·mL^(-1), respectively) exhibited α-amylase inhibitory activity as efficacious as acarbose(IC_(50) 15.4 μg·mL^(-1))). Moreover, B extract, at 25 μg·mL^(-1), significantly decreased the non-mitochondrial oxidative burst that is often associated with inflammatory response in human monocytic macrophages.

Objective:To search for an efficient and inexpensive source of phytoconstituents with antioxidant potential and health promoting traits from bark and empty pods of acacia auriculiformis （A.auriculiformis）.Methods:Samples of bark and empty pod extracts were analyzed for bioactives（phenolics,flavonoids and proanthocyanidins） and subjected to free radical scavenging activity on DPPH*,ABTS?,OH?,O2*,and NO along with the determination of reducing power, iron chelating activity and peroxidation inhibition.Defensive action of extracts on biomolecules and cell membranes were evaluated by DNA nicking assay and haemolysis inhibition assay respectively,α-amylase andα-glucosidase inhibitory potentials were also determined. Results:All the bioactives analyzed were higher in bark（B） than empty pods（EP）[TPC:B （574.51±16.11）;EP（96.80±3.45） mg GAE/g.TFC:B（94.71±7.65）;EP（24（?）87±20.45） mg RE/g. Proanthocyanidins:B（2.81±0.31）;EP（1.25±0.01） mg LE/100 g DM]except flavonoids.Both the extracts showed higher quenching capacity on DPPH and ABTS（DPPH:B（0.21±0.01）;EP（1.51±0.17） g extract/g DPPH.ABTS:B（111 519.14±79 340.91）;EP（80 232.55±32 894.12） mmol TE/g） with the FRAP of B（84 515.63±3 350.69） and EP（47 940.79±1 257.60） mmol Fe（（?））/g.Iron chelation was not observed.In addition,they showed lower quenching activity on OH?（B（48.95±1.72）;EP（34.94±1.62）%） and equivalent quenching on O2?（B（53.47±3.92）;EP（24.41±2.61）%）,NO（B（49.04±5.04）; EP（51.00±5.13）%）,peroxidation inhibition（B（67.50±5.50）;EP（55.l±2.3）%） and antihaemolytic potential（B（87.60±6.84）%） towards authentic antioxidant standards.Interestingly,Empty pod extracts are devoid of antihaemolytic activity.Both the extracts showed dose dependent DNA protection.Besides this,bark and empty pod extracts exhibited dual inhibiting potential againstα-amylase andα-glucosidase enzymes.Conclusions:On summarization,it insinuated that both bark and empty pods can be used for the preparation of antioxidant/nutraceuti

The aim of this study was to enhance the solubility and stability of acacia concinna extract by loading in a microemulsion for topical application. Both physical appearance and biological activities of the extract-loaded microemulsion were determined in comparison with the extract solution. Pseudoternary phase diagrams of three oil types including tea seed oil, grape seed oil, and sesame oil, together with polysorbate 85 or the mixture of polysorbate 85 and sorbitan oleate as surfactants, and absolute ethanol as a co-surfactant were constructed to optimize the microemulsion area. The selected microemulsion was then characterized for droplet size, polydispersity index, and viscosity. Tea seed oil exhibited the highest microemulsion area in the phase diagram because it had the highest unsaturated fatty acid content. The microemulsion composed of tea seed oil(5%), polysorbate 85(40%), ethanol(20%), and water(35%) exhibited Newtonian flow behavior with the droplet size and polydispersity index of 68.03 ± 1.09 nm and 0.44 ± 0.04, respectively. After 4% w/w of the extract was incorporated into the microemulsion, larger droplets size was observed(239.77 ± 12.69 nm)with a lower polydispersity index(0.37 ± 0.02). After storage in various conditions, both physical appearances and the stability of biological activity of the extract-loaded microemulsion were improved compared to the solution. Therefore, the A. concinna loaded microemulsion may be a promising carrier for further development into a topical formulation and clinical trials for pharmaceutical and cosmeceutical applications are also suggested.

The competition-density (C-D) effects for mean mass for tree, stem, branch and leaf were analyzed in acacia auriculiformis stands. Mean tree mass-density and mean organ mass-density were well explained by the C-D equation of tree and the C-D equation of tree organ, respectively. An equation describing the relationship between mean leaf area u and density was formulated that fit the u-data well. The relationship between mean tree mass w and the ratio of each organ to mean tree mass (wo/ w) was examined. With increasing w, the stem mass ratio wS/w increased, whereas the branch mass ratio wB/w and the leaf mass ratio wL/w decreased. The yield difference between the lowest-density stand and the high-density stand became greater with stand growth. However, the yield of the mid-density stand was slightly lower than the yield of the high-density stand during the experimental period. To produce the most desirable combination of demanding individual-tree size and relative high stem yield, the mid-density is recommended as proper planting density for future management of A. auriculiformis stands.
