Abstract

The results showed that the methanol extract from Clausena lansium was very effective against the growth of the Brassica campestris under light and non-light.At the concentration of 4 mg/mL,the inhibition to root,shoot and wet weigh were 99.17%,99.20%,72.42% respectively after lighting 3 h,which was higher than the non-light97.18%,82.07%,69.35%.Results of toxicology showed that the IC_(50) were 0.44 mg/mL under light and 0.48 mg/mL under non-light respectively;the IC_(50) to shoot was 0.99 mg/mL under light and 1.44 mg/mL under non-light;the IC_(50) to wet weigh was 1.48 mg/mL under light and 1.51 mg/mL under non-light;and the correlation coefficient was all above 0.90.Preliminaryly seperated the extract and the results indicated that the extract of ethyl acetate was the best.
