Phytochemicals and Constituents of Burdock root.
Main Effective Content:
Arctiin,C27H34O11,4.39%~6.35%. Arctigenin; Glucose; Matairesinol; Trachelogenin; Sesquilignan AL-D, AL-F; Lappaol A-F, H; Arachic acid; Stearic acid; Palmitic acid; Linoleic acid.
Burdock root contains: Approximately 27-45% up to 50% inulin, mucilage (up to 75% of the root is carbohydrate in the form of fructo-oligo-saccharides (FOS) including inulin); 0.06-0.18% essential oil with so far 66 identified components; antibacterial polyacetylenes; bitter substances (i.e. lactones); 1.9-3.65% polyphenols including caffeic acid, chlorogenic acid and other powerful flavonoid-type antioxidants; sitosterol and stigmasterol,volatile acids (acetic acid,propionic acid, butyric acid, isovaleric acid), non-hydroxyl acids (lauric acid, myristic acid, stearic acid, palmitic acid), tannin, polyphenolic acids.
Seeds:15-30% fixed oils, a bitter glycoside (arctiin), chlorogenic acid and vitamins A and vitamin B2.
Leaves: contain flavonoids and antibacterial substances, arctiol, fukinone and taraxasterol.
The roots contain starch, and the ashes of the plant, burnt when green, yield carbonate of potash abundantly, and also some nitre.

Isolation and Identification of Trace Lignans, Arctiin and Arctigenin, in Arctium lappa L. Leaves:
Burdock's fibrous primary root and rhizome expand to about 1 ft (0.3 m) underground. Most of the herb's medicinal constituents are stored in these underground parts. The entire plant has both nutritive and medicinal uses. The roots contain as much as 45% inulin, as well as alkaloids, essential oil, flavonoids, glycosides, mucilage, polyacetylenes, resin, tannins, and volatile oil. The seeds are rich in vitamins A and vitamins B and essential fatty acids. Both the seeds and the root have a demulcent quality that is soothing to the mucous membranes of the body. The leaves are generally less potent than the root and seed when used in medicinal preparations.
Abstract:The methods of polyamide column chromatography, reversed-phase high performance liquid chromatography (RP-HPLC), liquid chromatography-electrospray ionization mass spectrometry (LC-ESI-MS) and Fourier transform infrared spectroscopy (FTIR) for the isolation and identification of trace lignans, arctiin and arctigenin.
in, in Arctium lappa L. leaves were established. When the crude extracts of Arctium lappa L. leaves were chromatographed by polyamide column, and the fraction eluted by 100% methanol were concentrated and refrigerated, a white precipitate was obtained. Two main constituents were purified from the precipitate by
RP-HPLC. Compared with the UV-, LC-ESI-MS, HPLC and FTIR spectra of standard samples of arctiin and arctigenin, the two main purified constituents were identified as arctiin and arctigenin.
