英文摘要: Four oligosaccharides (penta-, hexa-, hepta- and octa-saccharide) derived from Paris polyphylla var. yunnanensis have been synthesized efficiently using a convergent glycosylation strategy. The tobacco (Nicotiana tabacum L.) growth bioactivities of the synthesized oligosaccharides were examined, using tissue-cultured seedlings grown on solid MS medium. After 2 or 3 weeks, all four oligosaccharides had stimulated tobacco seedling growth at 1.0 ppm and the pentasaccharide showed the most significant stimulus effects. Further experiments showed that the effects of pentasaccharide on tobacco growth had an obvious concentration-dependent relationship in the range of 0.1-1.0 ppm. This stimulus effect showed some decrease when the pentasaccharide concentration was higher than 1.0 ppm. At 1.0 ppm, pentasaccharide had the most significant effects, which caused a 520% fresh weight increase of tobacco. The bioactivity of these synthesized oligosaccharides suggested that they may be good prospects for the application in the control of plant growth and development.
