Embodiment Construction

[0034] Embodiments of the present invention are described in further detail below:

[0035] A kind of furanone compound, the chemical structural formula of this compound:

[0036]

[0037] The extraction method of this compound is as follows:

[0038] (1) Taking cat feces endophytic fungus DS37 secondary metabolites (9.2kg) as raw material with petroleum ether / ethyl acetate / methanol leaching 8 times, combining the extracts and filtering, recovering the mixed solvent, concentrating under reduced pressure to obtain Crude extract 1500g;

[0039] (2) Put the crude product extract obtained in step (1) on a silica gel chromatographic column, and use petroleum ether with a volume gradient of 1:0:0, 0:1:0, 0:1:1, and 0:0:1 respectively / Ethyl acetate / methanol eluent is eluted, obtains A (110g), B (420g), C (700g), D (100g) four components;

[0040] (3) For the B component extract of step (2), on a silica gel chromatographic column, use different gradients of petroleum ether / ethy...

Abstract

The invention discloses a furanone derivative as well as an extraction method and application thereof. The extraction method comprises the following steps: extracting decaisnea insignis endophytic fungus DS37 secondary metabolic products with petroleum ether / ethyl acetate / methanol, combining extracting liquid, filtering, recovering the mixed solvent and performing reduced-pressure concentration toobtain a crude product extractum; placing the obtained crude product extractum on a silica gel chromatographic column, and performing elution with petroleum ether / ethyl acetate / methanol eluents withdifferent volume gradient to obtain four components, namely A to D; and putting the component B on the silica gel chromatographic column to obtain six components, namely B1 to B6, continuously puttingthe component B6 on the silica gel chromatographic column, performing elution with petroleum ether / ethyl acetate / methanol eluents with different volume gradient to obtain nine components, namely B6.1to B6.9, and recrystallizing the component B6.9 with methanol to obtain the furanone derivative. The furanone derivative is separated from the decaisnea insignis endophytic fungus DS37 secondary metabolic products; and the compound has high bacteriostatic activity.

Description

technical field [0001] The invention relates to the field of preparation of furanone derivatives, in particular to a furanone derivative and its extraction method and application. Background technique [0002] Decaisnea insignis (Griff.) Hook.f. & Thomson) is also called Decaisnea insignis (Griff.) Hook.f. & Thomson, and is a plant of the genus Decaisnea insignis (Lardiya balaeeae). Clumping deciduous erect shrubs, widely distributed in southwestern and central China. Akebia plant cat feces is a traditional folk Chinese herbal medicine in my country. It tastes pungent, sweet, and flat in nature. The root and fruit are sweet and cool. So far, research on cat feces has mainly focused on its phytochemical components, while relatively little research has been done on its endophytic fungi. Endophytic fungi refer to fungi that live in plants during at least one stage of their growth without causing significant adverse effects on plant tissues. According to reports, the main typ...
