e6“The ethanolic extract 1 000-4 000 μg·mL-1 in concentration and the water extract 4 000 μg·mL-1 in concentration both inhibited growth of B.pekinensis roots in length”
e7“both the ethanolic and water extracts 2 000-4 000 μg·mL-1 in concentration did the plants in height,and the water extract 4 000 μg·mL-1 in concentration did seedling dry weight of the plant,too,with the highest inhibition rates being 37.00%,20.95%,25.63%,22.30%,and 13.67%,respectively”
