To analyse the extraction quatity of total chromone, factor A and factor B have significant difference, the best extraction technology is A_2B_3C_(1-3)D_(1-3);
to analyse the extraction quantity of prim-o-glucosylcimifugin, factor A, factor B, factor C and factor D all have significant difference, the best extraction technology is A_2B_(2-3)C_3D_(2-3);
The results indicated that the optimum extraction technology was as follows: ginger 100 g,60 % acetone 1 000 ml,refluxing for 3 times and 2 hours per time.
The result showed that the optimal extraction technology conditions of aloe gel juice were : blanching treatment of 90℃/5min, color retention treatment of 0.05% sodium erythorbate+0.1%CA, enzymolysis of 0.05% Pectase under 45℃ for 1h.
Conclusion: The optimum extraction process was as follows: with 500 ml/L alcohol for 2 times, with the solvent volume 6,5 folds amount and reflux for 1.5,1.5 hours in turn.
ResultsThe optimum extraction process of the total saponins of Gymnema sylvestre has been established as follows:the concentration of ethanol 70%,ratio of material to liquid 1:6,extraction time 3h,2 times.
The results showed that the optimal extracting technology was different among the skins of selected fish. Under the optimal extraction conditions, the extraction ratios of collagens from these skins were 36.57%, 30.58%, 35.14% and 45.17% respectively, while the corresponding yields were 8.93%, 8.52%, 9.03% and 6.50% respectively.
An analytical procedure based on the solid phase extraction technology has been developed for the clean-up and concentration of Soxhlet soil extracts containing fluazifop-butyl and fluazifop by the use of a phenyl phase cartridge.
Pilot-scale reactive-extraction technology for fully integrated L-phenylalanine (L-Phe) separation in Escherichia coli fed-batch fermentations was investigated in order to prevent an inhibition of microbial L-Phe production by-product accumulation.
The effect of the intermode coupling at the exit window of a cavity on the energy extraction process is analyzed in a simple model in which the interacting modes are represented in the form of a system of two coupled cavities.
The water-soluble glucan was obtained from Pleurotus florida fruit bodies by hot water extraction, ethanol precipitation, DEAE cellulose dialysis and Sephadex G-75 gel filtration.
