The tests were performed using a rotary evaporator reflux system (Marconi). The initial pectin concentration was 1.0% (w/v), and temperature and acid concentration were the independent variables . For this, a 5.0 g portion of pectin was added to 500 mL of a solution of sulfuric acid in a distillation flask, and the mixture was refluxed for 5 hours.
Calebin-A is a curcuminoid compound reported to be present in Curcuma longa rhizome. The current study was aimed to isolate and characterize calebin-A from Curcuma caesia rhizome and its production through biotransformation approach using endophytic fungus. C. caesia rhizomes of different ages were subjected to analysis in order to investigate the age at which maximum calebin-A content is present.

The List of Possibilities is Endless The PolyScience Rotary Vacuum Evaporation System provides virtually unlimited possibilities to evaporate, distill, separate and purify liquids. You can now easily concentrate, capture and infuse flavors in your own kitchen. This kitchen breakthrough utilizes a vacuum pump to reduce atmospheric pressure allowing liquids to move to a vapor phase at low .
Then the organic phase was separated, collected, and dried with a rotary evaporator. The residual was dissolved in 500 μL 5% DMSO for immunoassay. The frequency shift in response to the water sample kept nearly the same as the blank, suggesting that the OCS content in the Xiangjiang river water is under the detection limit of this method.
2016-2-25 · 2.1. Origin, Extraction and Processing. The original source of carrageenan was the red seaweed Chondrus crispus (also known as Irish Moss). With the expansion of the carrageenan industry over time, the increasing demand for the raw material led to the introduction of the cultivation of species of Eucheuma, originally E. cottonii and E. spinosum, now referred to as Kappaphycus alvarezii and .
2019-10-29 · The supernatant was then neutralized, spun for 15 min at 20,000 g, and lyophilized overnight in a rotary evaporator (Speedvac, Savant Instruments, Farmingdale, NY; Flexi-Dry microprocessor lyophilizer, FTS Systems, Stone Ridge, NY). The lyophilate was then brought to a volume of ∼550 μl in deuterium oxide (99.8% enrichment; CIL).
2000-2-1 · The aqueous layer was discarded after each wash. The organic layer was then transferred to a 25-mL round-bottomed flask, and the solvents were removed on a rotary evaporator. The remaining 3-OH-ester was hydrolyzed by adding 2 mL of 100 g/L NaOH and refluxing for 15 min. The mixture was cooled and made acidic with 6 mol/L HCI.
Described is a Reactor assembly for analysing the effluent stream from at least one flow-through reactor, comprising: -at least one flow-through reactor for performing at least one chemical reaction, the reactor comprising -a reaction chamber (1), comprising a reaction zone (2), the reaction chamber being connected to -at least one reactor inlet (3) for at least one reactant, 10 upstream of .
2020-5-1 · Blackberries were kindly provided by Verdes Quimeras Ltd. Cy3glc was extracted from crushed blackberries fruits through methanolic solution (1:1; v/v; 0.1M HCl), under shaking for 24 h. The resulting anthocyanin-rich extract was filtered through a nylon membrane and subsequently concentrated on a rotary evaporator under vacuum.
