The hepatoprotective activity of flavonoid rhamnocitrin 4'-β-D-galactopyranoside (RGP) obtained from leaves of Astragalus hamosus L. against N-diethylnitrosamine (DENA)-induced hepatic cancer in Wistar albino rats was evaluated. Hepatic cancer in rats was induced by single-dose intraperitoneal
Loranthus tanakae Fr. et Sav. (Loranthaceae) is a species of mistletoe, a semiparasitic plant growing on the branches of Quercus and Betula species as host trees. In our ongoing search for bioactive compounds from endemic species in Korea, we have investigated to isolate the chemical constituents
Repeated chromatography of the EtOAc-soluble fraction from the 70% EtOH extract of the flower buds of Syzygium aromaticum (clove) led to the isolation and characterization of four new flavonol glucuronides, rhamnetin-3-O-β-d-glucuronide (1), rhamnazin-3-O-β-d-glucuronide (2),
Further investigation of the aerial parts of Alomia myriadenia revealed an halimane diterpene identified as ent-8S,12S-epoxy-7R,16-dihydroxyhalima-5(10),13-dien-15,16-olide along with the known ent-16-hydroxylabda-7,13-dien-15,16-olide, ent-12R-hydroxylabda-7,13-dien-15,16-olide,
This work was designed to obtain the valuable compounds with antioxidant, anti-proliferative and anti-inflammatory activities from Astragalus chinensis. Ethyl acetate fraction obtained from A. chinensis L.f. had significant antioxidant, anti-proliferative and anti-inflammatory activities.
Phyllanthus urinaria Linnea (Euphorbiaceae), is a traditional anti-hepatitis herb used in Taiwan. In continuation of our search for potent natural anti-inflammatory agents, from the ethanolic extract of this plant, nine compounds including phyllanthin (1), phyltetralin (2),
