Comfrey (Symphytum officinale L.) ialah tumbuhan saka yang berasal dari Eropah dan Asia yang diperkenalkan di Amerika Syarikat dan Amerika Selatan.Pada masa ini, tumbuhan ini boleh ditemui di beberapa negara termasuk Brazil. Lastly, the antioxidant activity was determined using four assays: DPPH and ABTS radicals scavenging assays, reducing power assay and 15-lipoxygenase inhibition assay. In addition, pyrrolizidine alkaloids were evaluated by HPLC-QQQ-MS/MS and acetylintermedine, acetyllycopsamine and their N-oxides were determined as major pyrrolizidine alkaloids in the comfrey root sample. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. Moreover, trimers and tetramers of caffeic acid (isomers of salvianolic acid A, B and C) were identified and quantified for the first time in comfrey root.

Up to date, key activity-determining constituents of comfrey root extracts have not been completely elucidated. Comfrey root preparations are used for the external treatment of joint distortions and myalgia, due to its analgesic and anti-inflammatory properties.
