The invention relates to a method for extracting and separating chlorogenic acid from chrysanthemum. The method comprises the following steps: after water-removing is performed to a chrysanthemum, the raw material is lixiviated with solvent under the ultrasonic or microwave action, the crude extract of the chlorogenic acid is obtained after through solid-liquid separation, and then the chlorogenic acid pure product is obtained after through resin adsorption, separation and elution. The solvent is water, organic solvent or organic solvent-water mixed liquor. The water-removing is performed to the chrysanthemum, and the chrysanthemum is lixiviated with organic solvent or water at assistance of ultrasonic sound and microwave. Therefore, the yield of the chlorogenic acid can be improved, the production cycle is reduced, the chlorogenic acid pure product is obtained not the mixture with other ingredients, and the chlorogenic acid monomer is extracted form one chrysanthemum. Therefore, the range of the raw material of the chlorogenic acid can be extended, especially for the chrysanthemum in Canada, the chrysanthemum can turn the harmful into the beneficial and waste into valuable after development and utilization, and the invention has good economic, social and environmental benefits.

Method for improving coastal saline soil by using solidago canadensis

InactiveCN102144492ASlow down and weaken floodingSimple and fast operationHorticultureSoil scienceLitter
The invention relates to a method for improving coastal saline soil by using solidago canadensis, in particular to a saline soil improvement project for improving the saline soil by using invasive plants, belonging to the technical field of soil improvement. The method comprises the following steps of: marking out a land parcel to be improved; removing a surface soil layer above the ground water level in parallel to form a flat pit; uniformly covering the flat pit with an isolating material to form an isolating layer, and filling soil on the isolating layer for flattening, wherein the isolating material is solidago canadensis, and the isolating layer is made from 1.5-2 m of collected solidago canadensis or dry solidago canadensis branches with nearly equal length; binding the solidago canadensis or dry solidago canadensis branches into bundles with about 40 cm in thickness, spreading the bundles in the pit and compacting the pit; and backfilling the surface soil. The method has the advantage of changing the waste solidago canadensis litters into the valuable for improving coastal saline soil, not only can a great amount of solidago canadensis litters be consumed, but also saline soil can be improved. Through the massive application of the method provided by the invention, the wide spreading of solidago canadensis can be relieved and weakened. The method is simple and convenient to operate, has low cost and is applicable to large-scale popularization and application.

Method for preventing and controlling invasion weeds solidago canadensis L. through animal and plant synergy effect

The invention belongs to the technical field of treatment of biological invasion malignant weeds, and particularly relates to a method for preventing and controlling invasion weeds solidago canadensisL. through the animal and plant synergy effect. The implementation method comprises the steps of putting of insects in the seedling stage, planting of cuscuta chinensis in the growing period, and secondary putting of insects in the growing period. Specifically, in the invasion area of the solidago canadensis L., larvae of argyrogramma albostriata bremeret grey are put, thus solidago canadensis L.leaves are eaten, and it is difficult for the leaves to carry out photosynthesis; cuscuta chinensis seeds are sowed in the later period, so that stalks of the solidago canadensis L. are killed, so that the nutrition transfer on the solidago canadensis L. is limited, the solidago canadensis L. is finally dead, and thus the ecological function is restored. The method is simple and high in operability, and has small interference with the ecology of the area, and the disadvantage is turned into the advantage. The multi-trophic-level co-evolution principle can be sufficiently utilized, the ecological chain of the argyrogramma albostriata bremeret grey, solidago canadensis L. and mantises is adopted, diffusion and spreading of the solidago canadensis L. can be effectively controlled, and the situation that the released argyrogramma albostriata bremeret grey is widespread and uncurbed can be avoided; the ecological balance is maintained.
