Contrastive Study on Content and Anti-oxidation Activity of Total Saponins from Cultivated and Wild Paris Plants in Southwest China

[Objectives]To study content of total saponins from cultivated and wild Paris herbs in Southwest China,evaluate its in vitro antioxidation activity,and explore the correlation between quality of Paris herbs and production place,variety,cultivated and wild varieties.[Methods]Colorimetric method of perchloric acid reaction was used,and content of total saponins from Paris herbs was determined by ultraviolet spectrophotometer at 406 nm. [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,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.
