A Novel Method to Extract Juglone from Juglans mandshurica Waste Branches Using a Water-in-Oil Microemulsion

نویسندگان

چکیده

Pruning of Juglans mandshurica produces many branches, which are potentially a rich source juglone although they usually discarded as waste. Herein, we describe water-in-oil microemulsion-based microwave-assisted extraction (MBMAE) method to isolate the found in waste branches from J. mandshurica. In our experiment, branch powder was added MBMAE system. Using optimized microemulsion system comprising Tween 80:n-propanol:n-hexane:water at 27:13.5:4.5:55 (w/w/w/w), and pH 5.6, an operating temperature 40 °C, time 63 s, power 400 W, yield 4.58 mg/g ratio 20:1 (mL/g). The using 1.86- 6.65-fold better than that obtained by ethanol (Ethanol-MAE) heat reflux (Ethanol-HRE), respectively. may be useful alternative traditional methods juglone.

Macrofluid-like Water-in-Oil Microemulsion

A self-consistent picture of the structure and structural changes in a water-in-oil microemulsion (as a model of supermolecular fluids) close to the percolation threshold has been established. The self-consistency is evidenced by the demonstration that light-scattering and viscosity data for these systems can be quantitatively predicted by a model based on fractal cluster distribution. The mode...

Sequential ultrasound-microwave associated extraction (SUMAE) is a combination of ultrasound waves and microwaves energies in which ultrasonic extraction is used as a pretreatment. It was performed to extract essential oil from Zataria multiflora. The extraction conditions were optimized by response surface methodology (RSM) and Central Composite Design (CCD). The antioxidant and antibacterial ...
