Notoginseng folium P.E Chemical Properties,Usage,Production

Preparation

Infiltration method: Pulverize Panax notoginseng into coarse powder (20-40 mesh), soak in 75% ethanol for 12 hours, and slowly infiltrate at about 2mL/kg·min-1 degree Reel, and collect the permeate liquid equivalent to the selected times of Panax notoginseng, which is concentrated under reduced pressure and vacuum-dried to give Notoginseng folium P.E.

Composition

Panax notoginseng contains a variety of active components of dammarane-type tetracyclic triterpenoid saponins. Ginsenosides-Rb1,-Rd,-Re,-Rgl,-Rg2,-Rhl, 20-O-glucose ginsenoside Rf, Panax notoginsenoside-R1,-R2,-R3,-R4,- R6, -R7, Gynostemma glycoside XVII; isolated from tuberous rhizomes: ginsenoside-Rb1, -Rb2, -Rd, -Re, -Rg1 and notoginsenoside R1; isolated from velvet root: ginsenoside -Rb1, Rg1, Rh1 and Dama-20(22)-ene-3β, 12β, 25-triol-6-OBD-glucopyranoside, etc.; isolated from Rhododendron: Ginsenosides Rb1, Rd, Re , Rg1, Rg2, Rh1, Panax notoginseng saponins R1, R2, R4. And from the water-soluble part of the root, the hemostatic active ingredient tahlin, also known as Panax notoginseng, is a special amino acid whose structure is β-N-oxalyl-D-α-β-diaminopropionic acid. , the content reaches 0.90%, and its optical isomer β-N-oxalyl-D-α-β-diaminopropionic acid is also separated, which also has hemostatic activity, but the content is very small; it also contains aspartic acid ( Aspartic acid), glutamic acid, arginine, lysine, leucine and other 16 amino acids, 7 of which are essential for human body, and the average content of total amino acids is 7.73%. The root also contains anticancer polyacetylene components: panaxine triol.
An active Panax notoginseng polysaccharide A is also obtained from the root, which is an arabinogalactan. It also contains inorganic elements such as iron, copper, cobalt, manganese, zinc, nickel, vanadium, molybdenum, and fluorine.
