A butyrolactone lignan dimer from Arctium lappa
Phytochemistry, 1994Abstract A novel lignan, diarctigenin, together with the known butyrolactone derivatives, arctigenin and arctiin, has been isolated from the seeds of Arctium lappa . Its structure was elucidated as bis-5′,5′-arctigenin by spectral analyses and chemical modification.

A desmutagenic factor isolated from burdock (Arctium lappa Linne)
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1984A desmutagenic factor was isolated from burdock (Arctium lappa Linne). This factor reduced the mutagenicity of mutagens that are active without metabolic activation, such as 4-NO2-1,2-DAB and 2-NO2-1,4-DAB, as well as mutagens such as ethidium bromide, 2-aminoanthracene, Trp-P-1 and Trp-P-2 requiring S9 for metabolic activation. It is resistant to heat

[A new norsesquiterpenoid from Arctium lappa leaves].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2023Chemical constituents were isolated and purified from ethyl acetate fraction of Arctium lappa leaves by silica gel, ODS, MCI, and Sephadex LH-20 column chromatography. Their structures were identified with multiple spectroscopical methods including NMR, MS, IR, UV, and X-ray diffraction combined with literature data.

Effect of Arctium lappa (burdock) extract on canine dermal fibroblasts
Veterinary Immunology and Immunopathology, 2013Although the biological activities of Arctium lappa (burdock) have been already investigated in human and other species, data evaluating the molecular mechanisms have not been reported in the dog. In this study we analyzed for the first time the effect of a root extract of burdock on molecular responses in canine dermal fibroblasts with H2O2 ...

THE CONSTITUENTS OF ARCTIUM LAPPA L
Chemistry Letters, 1972Abstract Ten components including two new sesquiterpenes have been isolated from the leaves of Arctium lappa L. The new compounds, dehydrofukinone (I) and arctiol (II) proved to be Δ9(10)-fukinone and 8α-hydroxyeudesmol respectively.
