Embodiment 1

[0024] Grind the Panax notoginseng medicinal material to a particle size of 20-80 mesh, weigh 10 g each and put them into four extraction tanks A, B, C, and D, add 5-10 times the volume, 35-90% ethanol solution to D tank, The temperature rises to 35-80°C, and the stage extraction takes 20-60 minutes. Orthogonal experiments were designed and extracted according to the key points of operation. After the extraction, the extracts were combined, the volume was measured, and samples were taken for analysis of notoginseng saponin R 1 , Ginsenoside R g1 and total saponin content. The results are shown in Table 1.

Embodiment 2

[0027] (1) Best technology tank group countercurrent extraction

[0028] Grind the Panax notoginseng medicinal material to a particle size of 20-80 mesh, weigh 10g each and put them into four extraction tanks A, B, C, and D, add 8 times the volume of 70% ethanol solution to the D tank, and the temperature rises to 50 ℃, phase extraction for 30min. Extract by operating points. After the extraction, the extracts were combined, the volume was measured, and samples were taken for analysis of notoginseng saponin R 1 , Ginsenoside R g1 and total saponin content.

Abstract

The present invention discloses a method for extracting saponins effective component from Chinese medicinal material notoginseng. Said method adopts the following steps: firstly, pulverizing notoginseng root to obtain notoginseng powder whose grain size is 20-80 meshes, utilizing four extraction tanks of A,B,C and D, respectively adding 10g of notoginseng powder into every extraction tank, then adding 35%-90% ethyl alcohol solution into said four extraction tanks respectively, heating to 35-80deg.C and extracting for 20-60 min., successively making extraction of D,C.B and A to make effective component contents in extracts of four extraction tanks be successively decreased, then combining extracts. Said method can greatly raise extraction efficiency of notoginseng saponins effective component.

Description

technical field [0001] The invention relates to a method for extracting effective components of saponins from Panax notoginseng medicinal materials, in particular to a method for extracting effective components of saponins from Panax notoginseng by adopting a tank group countercurrent process, belonging to the field of extracting effective components of natural medicines. Background technique [0002] Panax notoginseng is the dried root of Araliaceae (Panax notoginseng (Burk.) F.H.Chen), mainly produced in Yunnan, Guangxi and other regions of my country, and is a traditional precious medicinal material in China. Panax notoginseng mainly includes notoginseng saponin R 1 , Ginsenoside R g1 , R b1 , R d1 Saponins and other non-saponins such as Panax notoginsin, flavonoids, and volatile oils, among which saponin R 1 , R g1 , R b1 The content is higher. Studies have shown that Panax notoginseng has various pharmacological effects such as hemostasis, antithrombosis, protect...
