Optimization of Pectin Extraction from <i>Nephrolepis biserrata</i> Leaves Using Response Surface Methodology

Optimization of Pectin Extraction from Passion Fruit Peel using Response Surface Methodology

Pectin from passion fruit peels was extracted using citric acid extraction. The effects of citric acid concentration from 0.05 to 0.21 % (wt/wt), extraction time from 30 to 120 minutes and extraction temperatures from 35 to 85 ̊C on pectin yield and the degree of esterification (DE) were investigated. Using the central composite design (CCD), the optimized pectin yield was 6.44 % and degree of ...

Optimization of 1-deoxynojirimycin extraction from mulberry leaves by using response surface methodology.

Mulberry 1-deoxynojirimycin (DNJ, a potent alpha-glycosidase inhibitor) has therapeutic potency against diabetes mellitus. However, the amount of DNJ in mulberry leaves is low (about 0.1%), and a more effective extraction method is needed. Ultrasound-assisted extraction (UAE) was applied in this study for mulberry DNJ extraction, and five factors, the percentage of ethanol in the extraction sol...

Optimization of pectin extraction from pomegranate peels by 1 response surface methodology

Optimization of Ultrasound-assisted Acidic-solvent Extraction of Colchicine from Colchicum kurdicum (Bornm.) Stef. Using Response Surface Methodology

Background and objectives: Colchicum kurdicum (Bornm.) Stef. is a flowering perennial monocotyledon plant that has many important bioactive compounds especially colchicine and colchicine derivatives. In this study, the ultrasound-assisted acidic-solvent extraction method coupled with response-surface method was presented as the successful method for large scale extract...

Optimization of the Glycyrrhizic Acid Extraction from Licorice by Response Surface Methodology

This study aims to extract Glycyrrhizic Acid (GA) from Glycyrrhiza glabra L. (licorice) using a novel, high efficiency, and low-cost extraction method. Water was chosen as the proper solvent for the extraction process to eliminate the requirement of harmful and toxic solvents, prepare an environmentally friendly process, and reduce the costs. The effect of differe...
