以重庆产栀子为试材,采用随机群组抽样,HPLC测定栀子苷含量,x2检测研究群体栀子苷含量分布规律,为客观评价群体栀子质量和优良栀子选育提供依据.结果表明,重庆产栀子的栀子苷含量在1.47%～6.44%之间,平均含量为4.07%;x2=10.68410.05,栀子苷含量实际分布次数与由正态分布的理论次数差异不显著.重庆产栀子的栀子苷含量围绕约4%服从正态分布,质量符合中国药典标准.
Taking gardenia jasminoides in Chongqing as the test material, the content of geniposide was determined by HPLC, the distribution of geniposide in x2 was detected by HPLC, which provided the basis for objectively evaluating the quality of gardenia and the good gardenia. The results showed that the content of geniposide in gardenia produced in Chongqing was between 1.47% ~ 6.44% with the average content of 4.07%; x2 = 10.6841 0.05. And the number of theoretical distributions by normal distribution was not significant.The content of geniposide in gardenia produced in Chongqing was about normal distribution about 4%, and the quality accorded with the standard of Chinese Pharmacopoeia.
