Embodiment 1

[0016] The raw material used in the present invention is alfalfa (Medicago sativa L.). The dry aerial part of alfalfa was extracted with boiling water (30L×3). The water extract was concentrated in a water bath to about 10L, and 30L of 95% ethanol was added, stirred and left to stand. The precipitate was discarded, and the alcoholic solution was concentrated under reduced pressure until there was no alcohol smell, and then extracted sequentially with petroleum ether, chloroform, ethyl acetate and n-butanol (10L×3), and the extract was concentrated under reduced pressure to obtain samples of each layer. The chloroform extract was separated by column chromatography on silica gel (petroleum ether-acetone gradient elution). The petroleum ether-acetone (100:3) eluted fraction was further separated by silica gel column chromatography or preparative thin-layer chromatography to obtain compound ring (L-leu-L-isoleu). The ring (L-leuco-L-isoleuence) is made into water, emulsion, etc....

Embodiment 2

[0018] The ring (L-leu-L-isoleuence) that is commercially available or isolated from other animals, plants, microorganisms or obtained through synthesis is prepared into emulsion, water, etc. by conventional methods.

Embodiment 3

[0020] To test the activity of Huan (L-liang-L-isobright) on promoting the growth of wheat roots and shoots, immerse the dry and mature wheat seeds in the aqueous solution of Huan (L-bright-L-isobright) and incubate at 25°C in the dark After 48 hours, the wheat seeds were taken out, the seed shoot length and root length were measured, and compared with the blank group, the growth rate of shoot and root system was calculated. The compound exhibited the activity of promoting the growth of wheat roots at almost all tested concentrations, up to about 30%, but had little or no effect on buds.

Abstract

The invention provides a novel drought-resistant agent and growth regulator, that is, ring dipeptides compound ring (L-leucyl-L-isoleucyl), and the application of ring dipeptides compound ring (L-leucyl-L-isoleucyl) in the agricultural production. The invention systematically separates Medicago sativa L to get ring dipeptides chemical constituents, and analyzes the bioactivity to screen compounds that can reinforce the growth adverse resistance and the root growth of plants. The invention proves that the ring (L-leucyl-L-isoleucyl) can obviously promote the root growth of plants and strengthen the drought-resistant ability of plants. Therefore, the ring (L-leucyl-Lisoleucyl) is expected to be made into a novel plant drought-resistance agent and plant-growth-accelerator and be prepared into a variety of pesticide preparations that meet pesticide requirements. The structural formula is displayed as follow.

Description

technical field [0001] The present invention relates to a novel anti-drought agent and plant growth regulator cyclic dipeptide compound ring (L-leu-L-isoleu) and its application. Background technique [0002] Cyclic dipeptides are found in humans, animals, plants, fungi and bacteria. Cyclic dipeptides with different structures have significantly different biological functions, including inhibiting weeds, regulating calcium ion channels, antibacterial, specific catalytic Three-dimensional configuration and biological activity as a signal molecule for bacterial physiological regulation. Therefore, cyclic dipeptide compounds have great development potential in the development of drugs, antibiotics, agricultural biological herbicides and drought-resistant agents. The research on cyclic dipeptide compounds abroad is relatively active. IenagaK et al. have reported the drought resistance induction effect of cyclic dipeptide compounds containing hydroxyproline residues on plants. ...
