利用索氏提取法,通过分离、提取及浓缩获得臭椿树皮提取物。采用不同浓度的提取液处理播娘蒿种子,通过测量发芽率、幼苗高度和重量,确定了臭椿提取物对播娘蒿的抑制作用。试验表明,随着提取液浓度的增加,抑制率明显提高,随着时间的延长,抑制率呈下降趋势。其中,对播娘蒿重量的影响大于高度,对高度影响又大于发芽数。
Soxhlet extraction method was used to obtain the bark extract of Ailanthus altissima by separating, extracting and concentrating. The seeds of Artemisia annua were treated with different concentrations of extracts, and the inhibitory effects of Ailanthus altissima extracts on Artemisia annua were determined by measuring the germination rate, seedling height and weight. Experiments show that with the increase of extract concentration, the inhibition rate was significantly increased, with the extension of time, the inhibition rate showed a downward trend. Among them, the weight of Artemisia annua greater than the impact of height, the height is greater than the number of germination.
