preparation example Construction

[0027] The extraction methods of plant polysaccharides mainly include hot water extraction, ultrasonic mechanical crushing and microwave extraction. The structures, properties and functions of polysaccharides obtained by different methods are quite different. For Abutilon flower stems, it has been verified by experiments that the hot water extraction method is adopted, and the extraction time is longer. High temperature and long-term water extraction have a greater impact on the polysaccharide structure and the physiological activity of scavenging nitrite; while simple ultrasonic crushing treatment will Break the chemical bonds between polysaccharides, destroy the spatial structure of polysaccharides, and reduce the physiological activity of scavenging nitrite; microwave leakage during microwave extraction has a greater impact on experimental operators, so the requirements for equipment are high, and its research and application Has a certain degree of difficulty. In view of ...

Embodiment 1

[0047] The mensuration of the polysaccharide content of different velvetleaf parts of embodiment 1

[0048] In this embodiment, the structure of Abutilus roots, Abutilus leaves, Abutilus stems, Abutilus flowers and Abutilus fruits at the flowering stage are used as research objects, and the polysaccharide content in the research objects is determined.

[0049] Experimental method: collect samples, dry in the shade, pulverize, make into powder, take 10g of dry powder for later use. The polysaccharide is extracted by the conventional hot water extraction method, the specific method includes: adding 10 times the mass of distilled water to the dry powder, heating under reflux, and controlling the temperature at 70-75°C, extracting 3 times, 2 hours each time, combining the extracts, and reducing pressure Concentrate to about 50mL, add ethanol for alcohol analysis, and let stand for 24h. The sugar content was determined by the sulfuric acid-phenol method, with glucose as the stan...

Embodiment 2

[0051] The mensuration of the polysaccharide content of embodiment 2 different growth periods

[0052] The stems / flowers of Abutilon used in this example were used in different growth periods from April 2018 to October 2018, dried in the shade, and crushed for later use. Harvesting place Xuzhou City, Jiangsu Province Abutilon theophrasti Medicus planting test site. The method for measuring polysaccharide content is with reference to embodiment 1, test result is as follows figure 2 shown.

[0053] Depend on figure 2 It can be seen that with the prolongation of growth time, the content of velvetleum polysaccharides first increases and then decreases, and the content of velvetleum polysaccharides can reach a peak around July, and the velvetleum plants in this growth period can be collected as research objects.

Abstract

The invention relates to a abutilon theophrastiflower stem extract, a preparation method thereof and an application of the abutilon theophrasti flower stem extract in preparation of a nitrite degradation scavenger, aiming at an abutilon theophrasti flower stem plant structure in a specific growth period, a treatment method combining high-efficiency ultrasonic disruption treatment and a xanthan gum solution protective medium is selected, and by means of the treatment method, the abutilon theophrasti flower stem plant structure efficiently releases physiological activators, and the extraction rate is high.

Description

technical field [0001] The disclosure relates to an extract of Abutilon flower stems, a preparation method thereof and an application in preparation of a nitrite degradation scavenger. Background technique [0002] The information disclosed in this background section is only intended to increase some understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Abutilon theophrasti Medicus (scientific name: Abutilon theophrasti Medicus) is an annual subshrub herb of Malvaceae, with pilose stems and branches, heart-shaped leaves, finely serrated edges, dense stellate pilose on both sides; petiole is stellate pilose ; Stipules fall early. Flowers solitary in leaf axils, pedicels pilose; calyx cup-shaped, lobes ovate; flowers yellow, petals obovate; flowering period July-August. Distributed in tro...
