These results suggest that melilot may promote the creation of glucosides in knotweed produced on low nutrient substrates. In the lack of melilot, the greatest concentration of resveratrol derivatives was found in plants grown on clayC and the cheapest was found in plants grown on clay in both 2006 and 2007. In 2006, higher concentrations of resveratrol derivatives were recorded for c-Met kinase inhibitor plants grown in the presence of melilot on loess, in 2007 the effect of substrate wasn’t significant. Emodin was dramatically higher in plants grown in the presence of melilot on compost in 2006 and in plants grown on all substrates in 2007. In the absence of melilot, a high concentration of emodin was observed in plants grown on clayC in 2006. A low concentration of emodin was within plants grown on compost in 2007. In the presence of melilot, the result of substrate was not significant in either year. In the presence of melilot, the Plastid nitrogen concentration of roots and knotweed rhizomes only increased in plants grown on compost in 2006, during 2007, it increased in plants grown on all substrates except for clayC. Though nitrogen concentrations in knotweed grown without melilot were identical for plants grown on all substrates, nitrogen concentrations were highest in knotweed grown with melilot grown on the two lownutrient substrates, loess and clay. The consequence of melilot was more pronounced in the second year of the research, particularly regarding plants grown on clay, loess and clayCS. These plants accumulated about one gram of nitrogen in their below-ground buildings, which will be about two times as much as that noticed in plants grown on clay and/or loess. Carbon concentration in knotweed roots and rhizomes was not afflicted with the existence of melilot, except in plants grown on loess in 2006. There was a positive correlation between carbon and the concentrations of resveratrol derivatives in 2006, both in the absence CTEP and presence of melilot, indicating a considerable amount of organic carbon was bound in resveratrol and its derivatives. Phosphorus in knotweed rhizomes showed comparable values in 2006 as in 2007. The concentration of phosphorus in melilot reduced in both years in plants grown on clay in 2006, and in plants grown on clayC and loess. Nevertheless, there clearly was a distinct trend of paid off phosphorus levels in crops grown on all substrates. The highest concentration of phosphorus was found in knotweed grown on compost with and without melilot in both 2006 and 2007. Mycorrhizal colonisation was observed only in the origins of knotweed developed with melilot, melilot did actually serve as a mycorrhiza donor for knotweed. The VCD baseline was obtained by subtracting the VCD of just one enantiomer from that of the other, then dividing by two. The infrared standard was obtained by subtracting the IR spectrum of CDCl3 ARN-509 from that of the test. The -conformers of the molecule and a molecule were designed with Hyperchem 7.
