摘要： In first part of this study, the potato variety Q9 was found the most allelopathic variety. Therefore, in present study chemical analysis of variety Q9 was done and 7 compounds [1- (2, 6-Dihydroxy-4-methoxy-3-methylphenyl) ethanone (I), Gentiopicroside (II), beta-sitosterol (III), palmitic acid (IV), kaempferol (V), verbascoside (VI), and isoverbascoside (VII) were isolated by column chromatography and identified by structural analysis. Compounds I, II, VI and VII were present in methanolic extracts. These compounds stimulated the seedlings growth of A. fatua, however, but inhibited the seedlings growth of B. campestris. Hence, we presumed that these compounds in potato variety Q9, may control the B. campestris weed, hence, more in-depth research is needed.
