Description
Technical Field
The invention belongs to the technical field of natural product chemistry, and particularly relates to a compound with tobacco black shank resistance activity extracted from Dai medicine ear leaf shell of the genus Cassia of the family Leguminosae, and application thereof in preparing a medicine for resisting tobacco black shank.
Background
Tobacco black shank is one of the most destructive diseases in tobacco production, also called tobacco epidemic disease, and tobacco growers are called black stem crazy, black root and aconite. The main smoke producing areas in China all occur to different degrees, wherein Anhui, shandong and Henan provinces are historic severe areas; southern smoke areas such as Yunnan, guizhou, sichuan, hunan, guangdong, guangxi and Fujian are also quite common. At present, the prevention and control of the black shank are mainly realized by methods of rotation cultivation, variety gene improvement, biological pesticide and the like. Among them, control with biopesticides is the most commonly used and readily achievable method. Therefore, searching for more efficient biopesticide lead compounds has important significance for preventing and controlling tobacco black shank.
Radix seu folium Juglandis ImmaturusCassia auriculataL.) is a perennial shrub shawl herb of the genus Cassia of the family Leguminosae, is a common Chinese medicinal material in Yunnan province, has the effects of promoting heat and removing dampness, eliminating dampness and toxin, and treating main heat syndrome and heart failure, and is often used for treating cold-dampness diarrhea, wind-heat cough, conjunctival congestion and swelling and pain, carbuncle, sore furuncle and other diseases. Previous studyThe main active ingredients in the concha haliotidis are anthraquinone and chromone compounds. Of these two main active ingredients, anthraquinone (Anthraquinone) is a quinone type chemical. Anthraquinone derivatives are widely found in nature or can be synthesized artificially. Anthraquinones include products and dimers of varying degrees of reduction, such as anthracenols, oxidized anthracenols, anthracnones, and the like, and in addition, glycosides of these compounds. In natural products, anthraquinone is often present in the metabolites of higher and lower plant lichens and fungi, and has hemostatic, antibacterial, toxic materials removing, purgation, and diuretic effects. The invention discovers a novel anthraquinone compound from the cassia ear of the genus Cassia of the family Leguminosae, and is notable that the compound contains [2,3- ] in rare anthraquinone structurec]The novel skeleton molecule of the aza Zhuo Huanjie structural fragment has higher novelty in structure, and the compound has remarkable tobacco black shank resistance activity, has a control effect (72.6+/-3.8)% on tobacco black shank, is superior to a control effect (63.2+/-3.5) of control agricultural chloramphenicol, and can be used as a lead compound for resisting tobacco black shank for researching and developing biological pesticide for resisting tobacco black shank.
Disclosure of Invention
The first object of the present invention is to provide an anthraquinone compound having an activity against tobacco black shank; the second aim is to provide a preparation method of the anthraquinone compound with the activity of resisting tobacco black shank; the third aim is to provide the application of the anthraquinone compound with the activity of resisting tobacco black shank.
The first object of the present invention is achieved in that the anthraquinone compound with activity of resisting tobacco black shank is a light red jelly, and the molecular formula is: c (C) 21 H 17 NO 4 Designated as 2',3' -dihydro-5, 4' -dimethyl-6-methoxy-1HAnthracene [2,3 ]c]Azepine-1',9,10-trione, english name: 6-methoxy-5,4'-dimethyl-2',3'-dihydro-1'H-anthra[2,3-c]Azepine-1',9,10-trione. Characterized in that the compound contains [2,3 ]c]An aza Zhuo Huanjie fragment, the structure of the compound is as follows:
。
the second object of the invention is realized by taking concha haliotidis as a raw material, which comprises the following steps:
1) Sun-drying and pulverizing the whole plant of ear leaf Concha Haliotidis, extracting with a first solvent, concentrating, extracting with a second solvent, saturating the water phase with sodium carbonate, extracting with the second solvent, mixing, and concentrating to obtain extract a; the first solvent is an ethanol aqueous solution with the concentration of 90-96%; the second solvent is ethyl acetate;
2) Dissolving the extract a with a third solvent, separating by a silica gel column, performing gradient elution with chloroform-acetone solution, and collecting a part with the volume ratio of chloroform-acetone solution of 8:2 to obtain an elution component b; the third solvent is methanol, ethanol or acetone;
3) Purifying the eluting component b by a sephadex column to obtain a crude product of the target compound; and separating the crude target compound by HPLC chromatography to obtain the pure target compound.
The anthraquinone compound structure with the tobacco black shank resistance prepared by the steps can be identified by the following method:
TABLE 1 Compounds 1 H NMR 13 C NMR data (CDCl) 3 )
