摘要
目的 检测芹菜提取物中总黄酮含量 ,为以芹菜提取物为原料的保健食品质量控制提供依据。方法 分别用芦丁和槲皮素作为标准品 ,分别采用比色法检测芹菜提取物中的总黄酮含量 ,并比较了两种方法的回收率。结果 以芦丁为标准品时 ,芹菜提取物中总黄酮含量为 1 0 5 % ,回收率为 10 2 % ,以槲皮素为标准品时总黄酮含量为 1 11% ,回收率为 99 5 6 %。结论 测定芹菜提取物总黄酮的两种方法均简便可行 ,重现性好。
Objective To determine the content of Flavonids in celery extract and provide information of quality controlling for health food which was made of celery extract.Methods Rutin and quercetin were used as standard material respectively.The colormetric method was used to determine the content of flavonoids in celery extract.Also,the recovery ratio of both methods were compared.Results When rutin was used as standard material,the average content of flavonids in celery extract was 1.05% and the recovery ratio was 102% while quercetin was used,the average cotent of flavonids and the recovery ratio were 1.11% and 99.56% respectively.Conclusion Both methods for determing the flavonoid contents in celery extract are simple and useful,meanwhile the determination repeatability is very good.
