| 中文摘要: |
| 陇西人工栽培黄芪不同生长期黄芪甲甙含量的定期检测结果表明,不同时期黄芪甲甙含量变化较大。生长初期,甲甙快速积累,6月中旬含量比例达到最高,随后甲甙含量比例下降,至9月中旬达到最低点。其后又快速增长,到10月中旬再次达到高峰。按照黄芪的产量和甲甙含量积累变化规律,为保障产量和活性成分含量最大,确定10月中旬为最佳采收时间。 |
| 英文摘要: |
| According to the observation in different growing stage of Astragalus membranaceus of artificial planting, the result indicates that contents of Astragaloside Ⅳ in the Astragalus membranaceus changed bigger in different growing stage. The contents reach the highest in the June, then the contents gradually descend by its lowest in September, subsequently, the contents rapidly raised until the middle of the October. Therefore, it is suggested that selecting the harvest time should be mainly based on the highest contents and yields of Astragaloside Ⅳ of Astragalus membranaceus in order to gain the highest yields and active ingredient. According to the result of the Growing Astragalus membranaceus harvest time is the middle ten days of October in Longxi. |
