Embodiment 1

[0087] Embodiment 1, the preparation of gerbera officinalis extract and its experiment of inhibiting phytopathogenic fungus

[0088] 1. Preparation of Gerbera officinalis extract

[0089] This step prepared the following eight kinds of gerbera extracts: 95% ethanol extract of gerbera, petroleum ether extract of gerbera, ethyl acetate extract of gerbera, water soluble matter of gerbera, ethyl acetate of gerbera-petroleum ether= 9% eluate, ethyl gerbera acetate-petroleum ether=20% eluate, ethyl gerbera acetate-petroleum ether=50% eluate, ethyl gerbera acetate eluate. The specific preparation method is as follows:

[0090] 1) Grinding and pulverizing the whole gerbera in liquid nitrogen, adding 95% ethanol aqueous solution to extract, collecting the extract, concentrating under reduced pressure to remove the ethanol in the extract to obtain an extract, which is Gerbera 95 % ethanol extract;

[0091] 2) disperse the gerbera 95% ethanol extract of step 1) into a suspension with ...

Abstract

The invention discloses a gerbera piloselloides extractive, as well as a preparation method and application thereof. The gerbera piloselloides extractive is any one of A1)-A7): A1) a gerbera piloselloides 95% ethyl alcohol extractive; A2) a gerbera piloselloides petroleum ether extractant; A3) a gerbera piloselloides ethyl acetate extractant; A4) a gerbera piloselloides ethyl acetate-ligarine = 9% eluate; A5) a gerbera piloselloides ethyl acetate-ligarine = 20% eluate; A6) a gerbera piloselloides ethyl acetate-ligarine = 50% eluate; A7) a gerbera piloselloides ethyl acetate eluate. Experimental results show that the gerbera piloselloides extractive has the inhibiting effect on plant pathogenic funguses, can be directly used for inhibiting plant pathogenic funguses, and can further be used for preparing an inhibitor for plant pathogenic funguses.

Description

technical field [0001] The invention relates to a gerbera officinalis extract, a preparation method and application thereof in the field of biotechnology. Background technique [0002] Plant pathogenic fungi are widely distributed all over the world, causing diseases of crops, forest trees, vegetables, commercial crops, and ornamental crops, often causing early chlorosis, leaf withering, falling leaves, withering and rot of plants, seriously affecting plant growth and development, yield and quality. Agricultural production and people's livelihood have brought serious losses. At present, the control of plant fungal diseases is still dominated by organic synthetic chemical agents, but the use of a large number of chemical pesticides has brought about a great negative ecological impact, and it is easy to cause phytotoxicity and drug resistance in plants, which seriously affects the resistance to phytopathogenic fungi. Application of formulations in agricultural production. In...
