The third procedure was microwave resonant cavity dynamic extraction(MRCDE). The results obtained by the three microwave-assisted extraction procedures were compared with those obtained by using traditional Soxhlet extraction.

A variety of physiological and biochemical parameters in the leaves of two Leguminosae species were monitored for 1, 7, 14, 21 and 28 d of drought stress. Soil water content decreased from 38.58% to 7.33% after exposure to 28 d of water stress. The photosynthetic carbon-assimilation rates of the two Leguminosae plants decreased for non-stomatal limitation with processing water stress. The malondialdehyde content and cell membrane relative conductivity of the two species increased significantly from 1 to 21 d and then decreased. S. moorcroftiana showed higher superoxide dismutase and peroxidase activities than C. maximovicziana during the 28 d treatment period. However, the catalase activities and proline content of C. maximovicziana were higher than those of S. moorcroftiana before the water stress treatment reached 21 d. Nine physiological and biochemical parameters were selected to comprehensively evaluate the two species' drought-resistance by the membership function values(MFV). The mean MFV indicated that S. moorcroftiana has a relatively stronger drought defense capability than C. maximovicziana. S. moorcroftiana mainly uses carbon-assimilation rate and osmotic adjustment to combat water deficiency.展开更多

The modified sophora japonica leaves possessed more adsorption sites and had more strongly adsorbed chemical groups, which were beneficial to the adsorption. We have further investigated the adsorption performance of the indoor benzene. The secondary regression orthogonal rotation was employed to optimize the preparation process for the optimal processing conditions and regression model. The effects of single factors such as particle size, temperature, and adsorbent dosage of the sophora japonica leaves were analyzed, and adsorption isotherms and adsorption kinetics were studied. The results show that the optimal adsorption conditions were as follows: sodium hydroxide concentration with 0.1 mol/L, water bath time for 70 min, water bath temperature at 60 ℃ and Ymax = 21.38%. The best single factors included particle size with 30 mesh, temperature at 25 oC, 3 g dosage, which are consistent with the Freundlich model, and the adsorption state was more inclined to multilayer active site adsorption with 25 mg/g of saturated adsorption amount;furthermore, the adsorption kinetics followed the quasi-secondary kinetic model(R2 = 0.9731) and the adsorption process was a physicochemical mixed adsorption process controlled by chemisorption;Compared with the adsorption effect, the removal rate to the benzene of modified sophora japonica leaves was significantly superior to other materials at the level 1%, namely, modified sophora japonica leaves > diatomite> bamboo charcoal > activated carbon > macroporous resin, and the modified biosorbent had a good cycle regeneration ability.展开更多

文摘Background:Cancer cachexia is a complex disease secondary to cancer,and no specific therapy for it has been found.The Chinese herb Kushen(Radix Sophorae flavescentis)is the dried root of Sophora flavescens Aiton,which has been widely applied in treating digestive and urinary inflammatory diseases.Matrine,one of the main components of Radix Sophorae flavescentis,can alleviate cancer cachexia.Methods:Compounds from Radix Sophorae flavescentis were screened using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform.The targets related to cancer cachexia were queried from the Therapeutic Target Database(http://db.idrblab.net),DisGeNET database(http://www.disgenet.org),and Search Tool for Interacting Chemicals database,related literature,and constructed cancer cachexia-protein network.Cancer cachexia-protein network was merged with compound-protein networks respectively using Cytoscape software as well as network topology data and key targets counting.Pathway enrichment analysis was conducted via the Database for Functional Annotation Bioinformatics Microarray Analysis.Protein crystal structures and compound structures were queried from RCSB and PubChem databases,respectively.Molecular docking was conducted using Discovery Studio software.Results:The anticancer cachexia compounds of Radix Sophorae flavescentis were screened as oxymatrine,matrine,and kurarinol,and targets such as BIRC2,TNF and STAT3 were found.The mechanisms of oxymatrine,matrine,and kurarinol have the characteristics of synergy and complementarity.Kurarinol has a mechanism similar to that of matrine,which includes the FoxO signaling pathway,insulin resistance and mTOR signaling pathway.TNF signaling pathway is a common signaling pathway of kurarinol,oxymatrine and matrine.Adipocytokine signaling pathway is the other common pathway of kurarinol and oxymatrine except for the TNF signaling pathway.Kurarinol can be successfully docked with CYCS,GPX2,BIRC7,etc.,and kushenol C can be successfully docked with IKBKB and PIK3CD.Conclusion:Kurarinol,matrine,oxymatrine,and kushenol C may be the key compounds of Radix Sophorae flavescentis treating cancer cachexia.Additionally,TNF signaling pathway is the key pathway for the synergistic action of kurarinol,matrine and oxymatrine.
