On the basis of the previous work of the research group, the orthogonal design method was further used to optimize the processing technology for reducing toxicity of fried Tripterygium wilfordii in Lysimachia christinae Decoction. A total of 9 processed products of T.wilfordii in L.christinae decoction were prepared by four factors and three levels orthogonal design table. The contents of triptolide in T.wilfordii were determined by high performance liquid chromatography(HPLC) before and after processing: 4.27, 3.92, 3.57, 2.75, 2.42, 2.66, 3.51, 1.87, 1.75, 2.03 μg·g~(-1). On this basis, the above processed products were orally given to mice for 28 days. 12 hours after the last administration, food fasting except water was provided, and 24 hours later, the eyeballs were taken for blood and liver tissue. Serum biochemical indexes, liver lipid peroxidation and antioxidant related indexes were detected by kit method. Twenty-eight days after oral administration of raw T.wilfordii, the levels of serum alanine aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP) and liver malondialdehyde(MDA) in mice increased by 91%(P<0.01), 46%(P<0.05), 73%(P<0.01) and 99%(P<0.01), while the liver antioxidant indexes such as superoxide dismutase(SOD), glutathione(GSH), glutathione peroxidase(GPX) and glutathione-S transferase(GST) significantly decreased(P<0.01). After administration of the processed products, the above indexes were significantly reversed(P<0.01 or P<0.05). Especially, the processing conditions of A_3B_2C_1D_3 had the best detoxification effect on T.wilfordii, which decreased the high levels of AST, ALT, ALP and MDA by 49%(P<0.01), 32%(P<0.01), 42%(P<0.01), and 17%(P<0.05). Therefore, the best processing conditions for T.wilfordii in L.christinae decoction were A_3B_2C_1D_3, namely "15% mass fraction of L.christinae, 1 h moistening time, 160 ℃ frying temperature, and 9 min frying time".

Purification, structure characterization and antioxidant activity of polysaccharides from Saposhnikovia divaricata / 中国天然药物

Polysaccharide from traditional Chinese herb, Saposhnikovia divaricata (Turcz.) Schischk. (SD) was extracted, fractionated and characterized in this work. Four fractions were prepared. Their molecular weight, monosaccharide compositions, linkage modes and structural properties were characterized with SEC-MALS-RI, HPAEC-PAD, GC-MS and NMR. SDP1 was assigned as a 1, 4-α-glucan with small amount of O-6 linked branches. SDP2 contained a big amount of the 1, 4-α-glucan and a small amount of arabinogalactan, while SDP3 possessed relatively lower amount of the 1, 4-α-glucan and a big amount of the arabinogalactan. SDP4 was defined as a pectic arabinogalactan. Four fractions showed antioxidant activities in both molecular and cellular levels and their activity was ranked as SDP4 ≈ SDP3>SDP2>SDP1. The 1, 4-α-glucan in SDP1 had the weakest, while SDP3 and SDP4 showed similar and the highest antioxidant activity. The arabinogalactan was the major component of both SDP3 and SDP4, which significantly contributed to the antioxidant activity of SDP.

Rapid Identification of Oligosaccharide Isomers by Electron Capture Dissociation in Combination with Metal Ions / 分析化学

Oligosaccharide isomers were distinguished by electron capture dissociation Fourier transform ion cyclotron resonance mass spectrometry ( ECD-FT-ICR-MS ) in combination with utiliZing alkali, alkaline earth, and transition metals ( Na+, Ca2+, Ba2+, Mg2+, Mn2+ and Co2+) as charge carriers in electrospray.Maltoheptaose, mannohexaose and laminarihexaose were taken as examples to investigate influence of metal ions on the extent of oligosaccharide fragmentation.The same types of fragmentation ions ( 0,2 A and 2,4 A) were obtained for barium- and calcium-adducted maltoheptaose.Mg2+ and Mn2+ had the similar influence ( 0,2 A, 2,4 A and 2,5 A ).Three cross-ring cleavage ions ( 1,4 A, 2,4 A and 2,5 A ) were generated in the spectrum of cobalt-associated maltoheptaose.But in the case of doping Na+into maltoheptaose, only 0,2 A ion was detected.It was found that the signals in the spectra of mannohexaose and laminarihexaose were worse than that in the spectrum of maltoheptaose, probably resulting from different numbers of adducted metal ions.The isomers, mannohexaose and laminarihexaose could be distinguished by ECD-MS in conjunction with the addition of Ca2+, Mg2+ or Co2+.The addition of Ca2+ was the best choice for analysis of oligosaccharides.

Effect of Sinomenine Hydrochloride on TLR4/NF-κB Pathway in Mice with Experimental Colitis / 中国药师

Objective:To study the effect of sinomenine hydrochloride on dextran sulfate sodium(DSS) induced experimental colitis in mice. Methods:The colitis model of BALB/c mice was established with DSS. The mice were randomly divided into six groups (n = 6):the normal control group and the model group(giving normal saline,0.2 ml),salicylazosulfapyridine treatment group (100 mg·kg-1) and sinomenine treatment groups (30,90,270 mg·kg-1). After continuous administration for 10 d,the disease activity index (DAI) and the tissue damage index in each group were evaluated. The mouse colons of TLR4 and Myd88 were detected using Western-blotting, and the expression of NF-κB in the colon tissues was detected using immunohistochemical method. Results:The DAI and the tissue damage index, and the expressions of TLR4, Myd88 and NF-κB in the colon tissues were significantly higher in the model group than those in the normal group (P < 0.01). Sulfasalazine treatment group and sinomenine at low,medium and high dose groups could reduce the DAI and the tissue damage score,and the expressions of TLR4, Myd88 and NF-κB in the colon tissues (P < 0.01) in a concentration-dependent manner. There was no significant difference between salicylazosulfapyridine treatment group and sinomenine at medium/high dose groups. Conclusion:Sinomenine reduces the expression of TLR4,Myd88 and NF-κB in mice with experimental colitis by regulating the TLR4/NF-k B signaling pathway to play a therapeutic role.
