Embodiment

[0031] (1) Preparation method of compound 1

[0032] The present invention has no special limitation on the preparation method of the compound 1, which can be prepared by conventional preparation methods known in the art. In the embodiment of the present invention, the preparation method is preferably as follows:

[0033] Dried chamaejasma root (10kg) was cut and pulverized and leached three times with 95% ethanol (20 liters each time), the extracts were combined and concentrated under reduced pressure to obtain the extract; the above extract was suspended in 4 liters of alkaline water ( PH=10-12) water, extracted 5 times with chloroform (1 L each time), concentrated under reduced pressure to obtain chloroform extract (122 g). The chloroform extract was passed through a silica gel column (silica gel 200-300 mesh, the same below), and carried out gradient elution with an organic solvent (petroleum ether-ethyl acetate 40:1, petroleum ether-ethyl acetate 20:1, petroleum ether-eth...

Abstract

The invention belongs to the technical field of medicinal chemistry, and particularly relates to application of a diarylpentane compound in stellera chamaejasme roots in herbicides. The diarylpentanecompound disclosed by the invention is a compound 3-Methoxy-1, 5-diphemylpentan-1-one, the compound has an obvious inhibition effect on the growth of elymus nutans roots, and the compound can be usedas an effective component of herbicides. Results of embodiments show that the diarylpentane compound provided by the invention has an obvious inhibition effect on growth of elymus nutans roots when the concentration is 10-100 [mu] g / mL.

Description

technical field [0001] The invention belongs to the technical field of medicinal chemistry, and in particular relates to the application of a diarylpentane compound in herbicides. Background technique [0002] Weeds in farmland refer to those herbaceous plants other than crops that grow in the field and on the edge of the field. They survive for a long time by adapting to local crops, cultivation, climate, soil and other ecological conditions and other social factors, and are an integral part of the agricultural ecosystem. . Many weeds have well-developed root systems, strong absorption capacity, fast growth at the seedling stage, and high photosynthetic efficiency, which seriously affect the yield and quality of crops. [0003] Weeds have strong growth ability, and the use of chemical herbicides is one of the main means of controlling weeds. Chemical herbicides are also known as herbicides, and there are more than 400 kinds of chemical herbicides commonly used around the ...
