Problems solved by technology

However, in the prior art, the utilization and development of the stems and leaves of Panax notoginseng is far from that of the roots, only about 5% of the stock is used, and the rest is discarded, resulting in waste
The reason is that most of the extraction of the stem and leaf components of Panax notoginseng is the purification of a single component. At present, no technology has been seen to extract three components at the same time, resulting in low extraction efficiency.

Embodiment Construction

[0071] S1. After cleaning the stems and leaves of Panax notoginseng, put them into a vacuum freeze dryer, lower the temperature to -30°C to -20°C, and keep it for 3 to 4 hours; vacuum drying: turn on the cold trap refrigeration mode, the cold trap device The refrigeration temperature is controlled at -40°C ~ -60°C, the vacuum degree is maintained at 10 ~ 30Pa for drying treatment, and after drying, it is crushed to 40 mesh;

[0072] S2. Add 50° pure water to the stem and leaf powder at a volume ratio of 1:4 and soak for 24 hours. During this period, put the container in a water-proof electric heating constant temperature incubator to keep the soaking liquid at 50°. After soaking, add 15 times 50° Ultrasonic extraction of pure water for 2 times, each time for 15 minutes, the filtrate was obtained by filtration, and the filtrate was concentrated under reduced pressure to 30% volume under the condition of 60-80°C and vacuum degree of -0.02MPa--0.06MPa to obtain the crude extract o...

Abstract

The major functional components in radix notoginseng stems and leaves comprise total saponins of the radix notoginseng stems and leaves, total flavones of the radix notoginseng and dencichine. The annual stock of the radix notoginseng stems and leaves can reach 8000-10000 tons, but in the prior art, only about 5% of the stock is used for the radix notoginseng stems and leaves, the rest is discarded, waste is caused. The reason is that most of the components of the radix notoginseng stems and leaves are extracted from single component, no technology for extracting three components simultaneously is seen at present, and thus the extraction efficiency is low. The invention provides an extraction process of radix notoginseng stems and leaves components for the problem, three components can beextracted simultaneously, the yield and content of each component are higher than the prior art, and the utilization of the radix notoginseng stems and leaves can be promoted.

Description

【Technical field】 [0001] The invention belongs to the field of extracting and manufacturing traditional Chinese medicines, in particular, it designs a process for extracting components of notoginseng stems and leaves. 【Background technique】 [0002] The main functional components in the stems and leaves of Panax notoginseng include total saponins in stems and leaves of Panax notoginseng, total flavonoids of Panax notoginseng and notoginseng. Different from the cell activation and anti-oxidation effects of Panax notoginseng saponins, the effects of total saponins from Panax notoginseng stems and leaves mainly lie in calming the nerves, analgesia, and lowering lipids. Panax notoginseng total flavonoids have the effects of increasing coronary blood flow, reducing myocardial oxygen consumption, and antiarrhythmia. Panax notoginseng has hemostatic coagulation effect. Therefore, in fact, for different medicinal needs, it is necessary to extract the above three components in the ...
