Embodiment 1

[0017] Embodiment 1: the chemical structural formula and physical constant of ferulic acid and derivative thereof, see table 1:

[0018] Table 1. Chemical structural formulas and physical constants of some ferulic acid and its derivatives

[0019]

Embodiment 2

[0024] Embodiment 2: the synthesis of trans-ferulic acid (1)

[0025] In a 50mL round bottom flask, add vanillin (10g, 0.065mol), malonic acid (7.5g, 0.07mol), toluene (15mL), pyridine and aniline in sequence, and react at 85-95°C for 2 hours. A 25% aqueous solution of potassium carbonate (35 mL) was added, followed by stirring. The aqueous layer was separated, and the pH was adjusted with concentrated hydrochloric acid. A large amount of solid was precipitated, filtered, washed with water, and dried to obtain trans-ferulic acid (11.6 g, 92%) in pale yellow needle crystals, mp 172-173°C.

Embodiment 3

[0026] Embodiment 3: the synthesis of target compound 20

[0027] Add 0.5g of trans-ferulic acid, 30mL of absolute ethanol, 0.1g of 10% Pd-C catalyst into a 100mL round-bottomed flask, blow hydrogen into it from a hydrogen balloon for 6 hours at room temperature, remove the Pd-C catalyst by filtration, and precipitate White solid 0.48g, yield 96%, mp 91-92°C.

Abstract

Anti-plant virus agent of ferulic acid, its derivatives, and the use thereof are provided. The structure of the ferulic acid is showed as formula (I). As a new anti-plant virus agent, the ferulic acid and its derivatives can well inhibit tobacco mosaic virus, pepper virus, tomato virus, sweet potato virus, potato virus, melon virus and maize dwarf mosaic virus and so on, and can effectively control viral diseases of many kinds of crops like tobacco, pepper, tomato, melon, foodstuff, vegetable, bean, etc., especially tobacco mosaic disease.

Description

technical field [0001] The present invention relates to a class of novel anti-plant virus agents and their applications, in particular to ferulic acid and its derivatives as anti-plant virus agents, and the interaction composition of ferulic acid and its derivatives and active components with anti-plant virus as anti-plant virus agents. Plant virus agents and their application in preventing and treating plant virus diseases belong to the technical field of pesticides. Background technique [0002] Ferulic acid (FA), chemical name 4-hydroxy-3-methoxyphenylacrylic acid) is a ubiquitous phenolic acid that cross-links with polysaccharides and lignin in plant cell walls to form part of the cell wall , is one of the active ingredients of traditional Chinese medicines such as Ferulicum, Angelica, Chuanxiong, Cimicifuga, etc. It has been widely used in medicine, health care products, cosmetic raw materials and food additives because of its strong antioxidant activity and antiseptic ...
