摘　　要：为确定玉竹品系优劣及不同品系最佳采收期,以二年生长叶小玉竹、长叶大玉竹、圆叶小玉竹、圆叶大玉竹4个品系为供试材料,采用回流提取法对其不同采收期的多糖含量进行提取和测定。结果表明:长叶小玉竹最佳采收期为9月15日,多糖含量为6.61%;长叶大玉竹最佳采收期为9月15日,多糖含量为3.24%;圆叶小玉竹最佳采收期为8月31日,多糖含量为3.65%;圆叶大玉竹最佳采收期为9月15日,多糖含量为4.14%;最佳品系为长叶小玉竹。In order to determine the quality and the best harvest time,taking small long-leaf and big long-leaf,small round-leaf and big round-leaf Polygonatum odoratum as materials which grown for two years.The polysaccharide content of four strains of Polygonatum odoratumin different picking time were extracted and determined through water extraction and alcohol precipitation method.The results showed that the best harvest time of small long-leaf Polygonatum odoratum was on September 15 th,whose polysaccharide content was about6.61%.The best harvest time of the big long-leaf Polygonatum odoratum was on September 15 th,whose polysaccharide content was about 3.24%.The best harvest time of small round-leaf Polygonatumodoratum was on August 31 th,whose polysaccharide content was 3.65%.The best harvest time of big round-leaf Polygonatum odoratum was on September 15 th,,whose polysaccharide content was 4.14%,and the best strain was small long-leaf Polygonatum odoratum.
