Embodiment 1

[0018] An ultrasonic extraction process of salidroside in natural rhodiola rosea, comprising the following method steps,

[0019] 1) Select natural Rhodiola rosea rhizomes with a water content of less than 15%, then put the natural Rhodiola rosea rhizomes into a screening machine, screen them clean, put them into a slicer, and cut them into 0.2cm thick slices;

[0020] 2) Put the rhodiola slices in the freezing equipment and freeze them at -5°C for 30 to 60 minutes. The purpose is to expand the internal tissues of the rhodiola slices and facilitate the extraction of subsequent processes;

[0021] 3) Put the frozen Rhodiola slices into the de-enzyming machine. The temperature of the inner wall of the de-enzyming machine is controlled at 150°C, and baked at 350 rpm for 1 minute. If it is too long, it will easily damage the internal fibrous tissue, if the time is too short, and the temperature is too low, it will not be completely extracted;

[0022] 4) When the surface temperat...

[0026] An ultrasonic extraction process of salidroside in natural rhodiola rosea, comprising the following method steps,

[0027] 1) Select natural Rhodiola rosea rhizomes with a water content of less than 15%, then put the natural Rhodiola rosea rhizomes into a screening machine, screen them clean, put them into a slicer, and cut them into 0.3cm thick slices;

[0028] 2) Put the rhodiola slices in the freezing equipment and freeze them at -5°C for 30 to 60 minutes. The purpose is to expand the internal tissues of the rhodiola slices and facilitate the extraction of subsequent processes;

[0029] 3) Put the frozen Rhodiola slices into the de-enzyming machine. The temperature of the inner wall of the de-enzyming machine is controlled at 150°C, and baked at 350 rpm for 1 minute. If it is too long, it will easily damage the internal fibrous tissue, if the time is too short, and the temperature is too low, it will not be completely extracted;

Abstract

The invention discloses an ultrasonic extraction technology for salidroside in natural Rhodiola rosea, and relates to the technical field of traditional Chinese medicine extraction. The ultrasonic extraction technology comprises the following steps: firstly, slicing salidroside; freezing, baking, freezing again, and baking again; grinding to obtain powder; adding salidroside powder into purified water at the temperature of 40-60DEG C; adding 10-15 times of water for dipping for 30 minutes; acting for 5-10min at the temperature of 50-55DEG C under the condition of ultrasonic power of 440W / L; carrying out ultrasonic extraction for three times, and combining filtrate; filtering and condensing filtrate; adding 95% alcohol of certain volume; standing for 24 hours; removing supernate; carrying out reduced pressure suction filtration; carrying out vacuum drying at the temperature of 70DEG C; drying to obtain polygahatous polysaccharide. The ultrasonic extraction technology disclosed by the invention has the advantages of short extraction time, low energy consumption, big medicinal material raw material handling capacity which is improved twofoldness or by multiple times, few impurities, low cost and obvious overall economic efficiency, and efficient ingredients can be easily separated and purified.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine extraction, in particular to an ultrasonic extraction process of salidroside in natural rhodiola rosea. Background technique [0002] Rhodiola belongs to the genus Rhodiola in the family Crassulaceae (Crassulaceae). It is a perennial herb or subshrub. It is distributed in Tibet, Yunnan, Guizhou, Northeast, Gansu, Xinjiang, Sichuan and other regions in China. It contains salidroside, flavonoids, Amino acid, tyrosol, trace elements, coumarin and more than 40 kinds of compounds have remarkable effects in anti-hypoxia, anti-fatigue, anti-virus, enhancing body immunity, anti-aging, anti-radiation, and two-way regulation of body functions. [0003] The pharmacological activity of Rhodiola is mainly manifested in anti-hypoxia, anti-fatigue, anti-microwave radiation, scavenging free radicals in the body, regulating and restoring the metabolic balance in the human body. Salidroside ca...
