Problems solved by technology

[0003] The composition of natural plants is complex. At present, the application of its active ingredients is mainly focused on the single extraction of one active ingredient, and the other ingredients are discarded. It is only simple to carry out direct extraction or reflux extraction, which has low technical content and is difficult to achieve additional value industrial upgrading

Embodiment 1

[0032] This embodiment proposes a method for simultaneously preparing sesame polysaccharides and oligosaccharide extracts, the flow process is as follows figure 1 shown. The specific implementation steps are as follows:

[0033] (1) Wash the sesame root and dry it in an oven at 60°C for 7 hours;

[0034] (2) crushed through a 60 mesh sieve;

[0035] (3) Take 10 g of pulverized mountain sesame powder, add 300 mL of distilled water, and stir evenly;

[0036] (4) heat up to 70°C, extract for 40 minutes under ultrasonic conditions with a power of 400W, the number of extractions is 2 times, and combine the extracts;

[0037] (5) The extract is cooled and left to stand, and the rotating speed is 8000r / min to centrifuge for 15min, and the upper layer is taken as clear night;

[0038] (6) The supernatant is distilled under reduced pressure at a temperature of 60° C., and the concentrated solution obtained is about 1 / 10 of the original volume;

[0039] (7) After adding 3 times the...

Abstract

The invention discloses a method for simultaneously preparing helicteres angustifolia polysaccharides and helicteres angustifolia oligosaccharide. The method mainly comprises the following preparation steps of: pre-treating andhelicteres angustifolia roots, performing water extraction, performing centrifugation, performing alcohol precipitation, concentrating liquid supernatant and performing drying, thereby obtaining helicteres angustifolia polysaccharides and helicteres angustifolia oligosaccharide. According to the method disclosed by the invention, the interaction effect, activity and an extraction rate of various ingredients in an extraction process are sufficiently taken into consideration by utilizing difference of the polysaccharides and oligosaccharide; an ultrasonic method is adopted to extract, so that the advantages of being high in extraction rate and saving time are achieved; and ethyl alcohol is recycled in an extraction process, so that cost is greatly saved. The helicteres angustifolia polysaccharides and helicteres angustifolia oligosaccharide extracted by the method have the effects of decreasing blood sugar, resisting oxidization and having antitumor activity, and can be developed into healthcare food and drugs.

Description

technical field [0001] The invention relates to the field of natural plant extracts, in particular to a method for simultaneously separating and extracting polysaccharides and oligosaccharides from Sesame chinensis. Background technique [0002] Sesame (Helicteres angustifolia L) is a sycamore plant, which has a bitter taste and a cold nature, and can relieve exterior heat, detoxify and reduce swelling. Sesame is first recorded in "The Nature of Raw Herbal Medicine", and it is a commonly used Chinese herbal medicine among the people. Sesame polysaccharides and oligosaccharides have various biological activities such as lowering blood sugar, anti-tumor, and enhancing immunity, and have shown good application prospects in the fields of medicine and food. [0003] The composition of natural plants is complex. At present, the application of its active ingredients is mainly focused on the single extraction of one active ingredient, and the other ingredients are discarded. It is ...
