摘　　要：目的比较不同采收期甘草Glycyrrhizae uralensis、光果甘草Glycyrrhizae glabra、胀果甘草Glycyrrhizae inflate、刺果甘草Glycyrrhizae pallidiflora、黄甘草Glycyrrhizae eurycarpa的产量和其有效成分甘草苷、甘草酸的含有量。方法以1~3年生、不同采收期的甘草为原料,称重法测定其干重（产量的主要因素）,HPLC法测定甘草苷和甘草酸含有量。结果甘草苷、甘草酸的含有量以及干重均依次为甘草〉光果甘草〉胀果甘草〉刺果甘草〉黄甘草、3年生〉2年生〉1年生、当年秋季〉次年春季。结论在人工栽培条件下,我国西北干旱荒漠与半荒漠地区应选用3年生的甘草进行培育,最佳采收期为当年秋季。AIM To compare the yields of Glycyrrhizae uralensis,Glycyrrhizae glabra,Glycyrrhizae inflate,Glycyrrhizae pallidiflora and Glycyrrhizae eurycarpa in different picking time and contents of effective constituents（ liquiritin and glycyrrhizic acid）. METHODS With one-,two-and three-year-old licorice in different picking time as raw materials,the dry weight（ main factor of yield） was determined by weighing method,and HPLC was adopted to detect the contents of liquiritin and glycyrrhizic acid. RESULTS The contents of liquiritin and glycyrrhizic acid,together with dry weight,were all in sequence of G. uralensis G. glabra G. inflate G. pallidiflora. G. eurycarpa,three years two years one year,and autumn current year spring next year. CONCLUSION In the condition of artificial cultivation,three-year-old G. uralensis should be selected to cultivate in northwest arid desert and semi-desert areas in China,and the best picking time is autumn current year.
