Embodiment 1

[0059] The preparation of embodiment 1 pseudoblack spiny ants extract

[0060] Take 1000g of Pseudomonas spinosa powder, add ethanol with a volume concentration of 95% and heat and reflux for extraction 3 times, 2L each time, combine the extracts, recover the ethanol under reduced pressure to obtain the primary oil. The extract is obtained by extracting with petroleum ether (wherein the boiling point of petroleum ether is 60°C-90°C), recovering the solvent and drying at low temperature.

Embodiment 2

[0061] The preparation of embodiment 2 Pseudomonas spiny ants extract

[0062] Take 1,000 g of Pseudomonas spinosa ants powder, add ethanol with a volume concentration of 90% and heat and reflux for extraction 3 times, 2 L each time, combine the extracts, recover the ethanol under reduced pressure to obtain primary oil. The extract is obtained by extracting with petroleum ether (wherein the boiling point of petroleum ether is 60°C-90°C), recovering the solvent and drying at low temperature.

Embodiment 3

[0063] Embodiment 3 Preparation of Pseudomonas spinosa ants extract

[0064] Take 1000g of Pseudomonas spinosa powder, add 100% ethanol and heat and reflux for extraction twice, 3L each time, combine the extracts, recover the ethanol under reduced pressure to obtain the primary oil. The extract is obtained by extracting with petroleum ether (wherein the boiling point of petroleum ether is 60°C-90°C), recovering the solvent and drying at low temperature.

Abstract

The invention relates to the field of biomedicine, in particular to a Polyrhachis vicina roger extract as well as an extraction method and an application thereof. According to the extraction method of the Polyrhachis vicina roger extract, ethanol and petroleum ether are adopted for extraction. The insect resource is rich, the extraction method is simple and easy to implement, raw materials are convenient and easy to obtain, and mass preparation of the Polyrhachis vicina roger extract can be realized; the cost is low, the pollution is low, mass production is facilitated under energy saving and emission reduction conditions, and the industrialization prospect is very bright. The Polyrhachis vicina roger extract has multiple purposes in aspects of food, health-care products and preparation of drugs for special diseases, and the clinical application of the Polyrhachis vicina roger extract has the scientific basis in prevention or treatment of depression.

Description

technical field [0001] The invention belongs to the technical field of natural extracts, and in particular relates to an extract of Pseudomonas spp. and its extraction method and application. Background technique [0002] Depression, also known as depressive disorder, is the main type of mood disorder with significant and persistent low mood as the main clinical feature. The main clinical manifestations are depression, slow movement, guilt, self-blame and self-crime; in severe cases, there will be suicidal tendencies and other symptoms. It has the characteristics of high morbidity, high disability, high suicide rate, high recurrence and heavy social burden. In recent years, the incidence of depression has risen sharply, and it currently ranks fourth among disabling diseases in the world. It is estimated that by 2020, the incidence will be second only to ischemic heart disease. Moreover, the treatment cost of depression is expensive at present, and it is estimated that its ...
