Activity-guided fractionation of a MeOH extract of the roots of Saussurea lappa C.B.Clarke (Compositae), using an in vitro protein tyrosine phosphatase 1B (PTP1B) inhibition assay, led to the isolation of four active constituents: betulinic acid (1), betulinic acid methyl ester (2), mokko lactone
BACKGROUND
Severe destructive hepatic injuries can be induced by acetaminophen overdose and may lead to acute hepatic failure.
OBJECTIVE
To investigate the ameliorative effects of Arctium lappa root extract on acetaminophen-induced hepatotoxicity.
METHODS
Rats were divided into 4 groups: normal
The sesquiterpene lactone fraction of Saussurea lappa roots was evaluated for its effect on the transudative, exudative and proliferative phases of inflammation using the cotton pellet granuloma assay in rats. The fraction (25-100 mg/kg, p.o.) showed significant dose-dependent inhibition of the
A new lignan glycoside, named 1,5-dihydroxypinoresinol-4'-O-beta-d-glucopyranoside (1), has been isolated from the EtOH extract of the roots of Saussurea lappa, together with twenty known compounds: (+)-1-hydroxypinoresinol-1-O-beta-D-glucopyranoside (2), fraxiresinol-4'-O-beta-D-glucopyranoside
In the present study, we obtained a dried burdock root extract (DBRE) rich in caffeoylquinic acids derivatives. We performed the chemical characterization of DBRE and explored its antihyperglycemic potential in both in vitro and in vivo experiments. Chemical analysis of DBRE using LC-MS and GC-MS
OBJECTIVE
Arctium lappa (burdock), (A. lappa) root has hypoglycemic and antioxidative effects, and has been used for treatment of diabetes in tradition medicine. This study was conducted to evaluate the antidiabetic and hypolipidemic properties of A. lappa root extract on nicotinamide-streptozotocin
