[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
