摘　　要：目的:通过研究龙葵不同产地、生境、不同生长周期及不同药用部位中可溶性糖的动态规律,为制定龙葵的规范化栽培措施提供理论依据。方法:以80%乙醇8 mL,80℃下超声提取2次,每次30 min;以苯酚—硫酸比色法测定可溶性糖含量。结果:龙葵中可溶性糖的含量基本符合以下规律:根<茎叶<果实。不同生长周期的根及茎叶满足:初果期<花蕾期<成熟期<始熟期<苗期。不同生长周期的果实满足:青果<幼果<成熟果实。结论:在龙葵的生长过程中,龙葵中可溶性糖含量随着其生长发育进程而发生变化。根据龙葵不同时期碳代谢在各器官中的变化,采取合理的栽培技术,统筹控制龙葵生长发育,以促进龙葵高产、优质。Objective：To investigate the origin of different Solanum nigrum,habitat,at different growth stages and different medicinal parts of the dynamics of soluble sugars,for the development of standardization of S.nigrum cultivation measures provide a theoretical basis.Method：80% ethanol 8 mL of ultrasonic extraction two times,each time 30 min,with phenol-sulfuric acid colorimetric determination of soluble sugar content.Result：Solanum nigrum soluble sugar content the comply with the following rules： root stem and lea fruit.Different growth cycle root and stem and leaf to meet： the early fruiting stage bud Issue mature before maturity seedling.Different growth cycle of fruit to meet： fruit young fruit ripe fruit.Conclusion：In the growth process of S.nigrum,S.nigrum soluble sugar content as its growth and development process of change.S.nigrum according to carbon metabolism at different times in its various organs in the development and changes in cultivation techniques to take reasonable and appropriate fertilizer measures to better co-ordinated control of a good growth of S.nigrum,S.nigrum in order to promote high yield,quality.
