Description

Technical Field

[0001] The invention relates to the technical field of plant adventitious root tissue culture technology, and in particular to a method for producing notoginseng saponins and ginsenosides by utilizing cotyledon embryos of notoginseng. Background Art

[0002] Panax notoginseng, also known as Tianqi, belongs to the genus Panax in the Araliaceae family, along with ginseng, American ginseng, and bamboo ginseng. It is a perennial herbaceous plant with perennial roots. It is mainly distributed in Yunnan and Guangxi in China, growing under forests or on hillsides at an altitude of 400-1800 meters. Panax notoginseng usually takes more than three years to be harvested, and the harvest period is from October to December. The main medicinal parts are roots and rhizomes. "Supplement to Compendium of Materia Medica" records that "ginseng is the best for replenishing qi, and Panax notoginseng is the best for replenishing blood." Modern pharmacological studies have shown that Panax notoginseng has anti-inflammatory, lipid-regulating, anti-platelet aggregation, anti-tumor, anti-thrombotic, prevention and treatment of atherosclerosis and fatty liver, prevention of myocardial infarction, and promotion of liver regeneration and angiogenesis.

[0003] As the medicinal effects of Panax notoginseng are gradually discovered, wild Panax notoginseng has become extinct due to the excavation of the dry pond. Panax notoginseng cultivated in the field has serious problems such as continuous cropping obstacles, diseases, heavy metal residues in the soil and long growth cycle, which affect the quality of Panax notoginseng and restrict the development and application of Panax notoginseng products. As the country's requirements for the quality of medicinal plant products increase and the application of Panax notoginseng is gradually expanded to the fields of skin care products and cosmetics, Panax notoginseng cultivated in the field is difficult to meet the requirements. Since the cultivation process of Panax notoginseng cotyledon embryos is completely separated from the soil, does not involve pesticides, has no heavy metal pollution, and has a short cycle and is not affected by the external climate environment, it overcomes the above-mentioned problems of field cultivation and provides a new way for the production of Panax notoginseng saponin R1, ginsenoside Rg1 and ginsenoside Rb1. However, there are few reports on the method of producing Panax notoginseng saponin R1, ginsenoside Rg1 and ginsenoside Rb1 using Panax notoginseng cotyledon embryos.

[0004] In the related art, one scheme for producing Panax notoginseng cotyledon embryos is to first induce Panax notoginseng embryonic callus through different explants such as Panax notoginseng embryos, stem segments, young shoots, adventitious roots, etc. under different concentrations of hormones (2,4-D and 6-BA), and then use the embryonic callus to differentiate into somatic embryos on a hormone-free medium, and then use different concentrations of hormone GA to induce somatic embryos. 3Act on the somatic embryo to develop into a cotyledon embryo. The disadvantage of this scheme is that the entire culture cycle starting from the induction of embryonic callus is time-consuming, and the complexity and high cost of the process limit its application in industrial production. Another scheme is to induce the embryonic callus of Panax notoginseng through different explants such as Panax notoginseng seed embryos, stem segments, tender shoots, adventitious roots, etc. on different concentrations of hormones (2,4-D and 6-BA). The embryonic callus differentiates for 6 weeks on a low concentration of 2,4-D culture medium to form a spherical embryo, and the spherical embryo differentiates for 4 weeks in a bioreactor to form a cotyledon embryo containing a radicle morphology. The disadvantage of this scheme is that a large number of secondary embryos will be produced, that is, multiple embryos are combined together, affecting subsequent normal development. Secondly, deformed embryos may appear during the culture process in the reactor. In addition, the culture cycle of this scheme is relatively long, and the whole process needs to last for more than 10 weeks. At present, the production of saponins using bioreactors generally uses Panax notoginseng callus, but the saponin content of callus is low and the production efficiency is low. Therefore, it is necessary to provide a method for producing notoginsenosides and ginsenosides using notoginseng cotyledon embryos, which is suitable for industrial mass production needs and has high production efficiency. Summary of the invention

[0005] In order to overcome the problems existing in the background technology, the present invention provides a method for producing notoginsenosides and ginsenosides using Panax notoginseng cotyledon embryos. Large-scale production of cotyledon embryos can be completed in only 4-6 weeks, which significantly accelerates the production process, is suitable for industrial mass production needs, and has high production efficiency.

[0013] S6. Dry the cotyledon embryos obtained in step S4 at 45° C. and grind the powder. Pass the powder through a No. 3 sieve to extract notoginsenoside and ginsenoside.

[0014] In the above technical solution, the plate culture medium in step S2 is WPM culture medium with a pH of 5.8 and 30 g / L sucrose, 2 mg / L 2,4-D, 1 g / L CH, 1 g / L PVP, 1 g / L activated carbon and 3 g / L Phytagel added.

[0015] In the above technical solution, the embryonic callus tissue described in step S3 is placed in a conical flask containing 30-50 mL WPM culture solution supplemented with 30 g / L sucrose, and a magnetic stirring rotor is placed in the flask to stir for 10 minutes to disperse the cells.

[0016] In the above technical solution, the mechanical stirring bioreactor in step S4 is a 7L mechanical stirring bioreactor.

[0017] In the above technical solution, the input parameters of the mechanical stirring bioreactor described in step S4 are pH 5.6-5.7, temperature 23-25°C, rotation speed 150-250rpm, and ventilation volume 1-3L / min.

[0019] In the above technical solution, the conical flask in step S5 contains 30-100 mL of liquid culture medium.

[0020] In the above technical solution, the liquid culture medium in step S5 is a WPM liquid culture medium supplemented with 50-80 g / L sucrose / maltose, 4-16.6 g / L MES, and 0.5-1 g / L glutamine.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention proposes a new method for obtaining notoginseng saponins and ginsenosides (mainly notoginseng saponin R1, ginsenoside Rg1 and ginsenoside Rb1) of the medicinal ingredients of Panax notoginseng without destroying natural resources and relying on land. This method breaks through the limitation of relying on land resources in the traditional planting process, does not need to destroy the natural environment, ensures the green production of Panax notoginseng medicinal materials, and has no chemical residues, thereby realizing a pure and safe raw material supply. In addition, this method has a short culture cycle, and only 4-6 weeks are required to complete the large-scale generation of cotyledon embryos, which significantly accelerates the production process and is suitable for industrial mass production needs.

[0023] 2. The present invention produces notoginsenoside R1, ginsenoside Rg1 and ginsenoside Rb1 by culturing cotyledon embryos. The total saponin content in the cotyledon embryos obtained by the present invention is much higher than the saponin content in the callus tissue, which can improve the production efficiency of saponins and enhance product quality.

[0024] 3. The present invention has an efficient circular production, which obtains spherical embryos and heart-shaped embryos by directly utilizing the differentiated Panax notoginseng embryonic cells in the liquid culture medium, thereby eliminating the step of starting over from seed embryos. These Panax notoginseng embryonic cells can rapidly differentiate into a large number of spherical embryos and heart-shaped embryos in just 3 to 5 weeks, which can then be efficiently used for the large-scale production of cotyledon embryos, thus constructing a closed production loop.

[0025] 4. In order to meet the specific needs of different culture stages, the present invention adopts a strategy of step-by-step expansion of culture and combines a variety of culture methods and containers: embryonic callus induction stage - solid culture medium; globular embryo heart-shaped embryo differentiation stage - triangular flask liquid culture; cotyledon embryo differentiation stage - liquid fermentation tank culture.
