To study the dynamic accumulation of glycyrrhizic acid (GA) in semi-wild Glycyrrhiza uralensis Fisch. so as to determine its optimal harvest time.
The content of GA in the plant samples was determined by HPLC.
In the same growth period, the content of GA in the plant reached its highest peak in June or July, decreased gradually from August, and reached the lowest in November or December. Then the content of GA increased gradually from next March, and finally reached the highest in June or July again. There was no obvious difference between the content of GA in the one-year-old and the two-year-old Glycyrrhiza uralensis. But the content of GA in the three-year-old increased markedly, and its GA content was much higher than that of the one or two-year-old.
The optimal harvest time of semi-wild Glycyrrhiza uralensis is in July or August after transplanted three years.
研究半野生乌拉尔甘草中甘草酸(GA)的动态积累情况,以确定其最佳采收期。
采用高效液相色谱法测定植物样品中GA的含量。
在同一生长时期,植物中GA的含量在6月或7月达到最高峰,8月起逐渐下降,11月或12月降至最低。然后从次年3月起GA含量又逐渐升高,最终6月或7月再次达到最高。一年生和两年生乌拉尔甘草中GA的含量无明显差异。但三年生的GA含量显著增加,且其GA含量远高于一年生和两年生的。
半野生乌拉尔甘草的最佳采收期是移栽三年后的7月或8月。
