We established the quantitative analysis method of the steroidal saponins in some species of the genus Paris and discussed their relations. Methods We detected the contents of 11 steroidal saponins in Paris samples with a Kromasel C18 （ 150 mm× 4.6 mm ID, 5μm） column which was subjected to gradient elution with acetonitrile-water （30：70- 60：40, V/V） at a flow rate of 1 mL· min^-1 by HPLC-ELSD and established chemical cluster tree using SPSS 11 software. Results All the samples could be separated and calibration curves of 11 saponins were prepared. We successfully detected the contents of 11 steroidal saponins in 14 Paris spp. in 30 min. The recovery for the assay of saponins was between 95 % and 97 %. The RSD of precision of 11 saponins and stability of samples were below 3 %. Chemical phylogenetic tree based on saponin contents indicated that 17 samples of Paris spp. clustered separately. Conclusion The established method is accurate and convenient, and suitable for the quantitative analysis of these 11 steroidal saponins in Paris spp.. The chemical phylogenetic tree is in accordance with Takhtajian classical taxonomy.展开更多

The proliferation of SGC7901 cells was monitored by the MTT cell viability assay, while the nuclear morphology of apoptotic cells was assessed by Hoechst 33258 staining. Flow cytometry was performed to analyze the cell cycle progression of propidium iodide （PI）-stained SGC7901 cells and the apoptotic rate of annexin V/PI-stained ceils. Western blotting was used to examine the expression of several cell cycle proteins, including cyclin 131 and Cdkl, and the apoptosis-regulated proteins Bcl-2, Bax, cytochrome c, procaspase-9, and procaspase-3. The MTT assay demonstrated that PSI could induce significant dose- and time-dependent inhibition of SGC7901 cell proliferation. Marked morphological changes, including condensation of chromatin, nuclear fragmentation and apoptotic bodies were clearly shown on Hoechst 33258 staining. PS I treatment also resulted in the disruption of the cell cycle at Gz/M and the induction of apoptosis. Following PSI treatment, the cell cycle-related proteins cyclin B 1 and Cdkl were down- regulated. Expression of the pro-apoptotic protein Bax was increased, while anti-apoptotic protein Bcl-2 decreased. PSI treatment resulted in elevated cytoplasmic cytochrome c and activation of the apoptotic proteases caspase-9 and caspase-3. These data indicate that PS I acts as an inhibitor of proliferation in SGC7901 cells by inducing cell cycle arrest and mitochondria-dependent apoptosis. PSI is a potential therapeutic agent against human gastric carcinoma.展开更多

[Results]The lowest content of total saponins from cultivated and wild Paris herbs in Southwest China was0. 55%,while the maximum was 12. 24%,with obvious difference. Total saponins from Paris herbs had stronger clearance ability on free radical DPPH and stronger reduction ability on Fe^(3+),and the results showed good dose-effect relationship with concentration. Among them,S6 had the highest clearance ability on DPPH,which reached 89. 66%. In the determination of reduction ability,the absorbance of S16 reached3. 643 and was the highest,with very good reducing property. Content and anti-oxidation capacity of total saponins from Paris herbs in Southwest China did not have obvious correlation with production place,altitude and cultivation but was related to variety. [Conclusions]The quality of Paris herbs in Southwest China was unstable,and their anti-oxidation abilities were also different,and cultivation could not guarantee high quality. It should normalize cultivation,and develop planting industry of Paris herbs,which could guarantee stable supply of Paris herbs and stability and controllability of quality.展开更多

[Methods]Ultraviolet spectrophotometry was used to determine and contrast content of total saponins in root,stem and leaf from healthy and diseased plants. Infrared characteristic absorption peaks of healthy and diseased plants were found by infrared fingerprint method for comparative analysis.[Results]Total saponins content in root sample J4 of healthy plant reached 4. 89% and was the highest,while it was 0. 13% in stem sample J11 of healthy plant and was the lowest. Total saponins content in root sample B1 of diseased plant was 1. 68% and was the highest,while it was 0. 1% in stem sample B7 of diseased plant and was the lowest. In healthy and diseased plants,total saponins content in root was significantly higher than that in stem and leaf. Content of total saponins in root from healthy plant was significantly higher than that from diseased plant,and there was little difference in stem and leaf of healthy and diseased plants. Root sample Jg of healthy plant had obvious C-O characteristic vibration of polysaccharides and glycosides and absorption peak of O-H bending vibration in steroidal saponin near 1 160. 02 cm-1,while diseased plant had no obvious absorption peak. Near 861. 97 and 768. 07 cm-1,root sample Jg of healthy plant had significant C-C stretching vibration in sugar ring and characteristic absorption peak of characteristic vibration of steroidal saponin,while root sample Bg of diseased plant had no obvious characteristic peak. [Conclusions] Diseases significantly affected composition and content of total saponins and steroidal saponins from P. polyphylla var. chinensis,further affecting quality of P. polyphylla var. chinensis.展开更多
