We have investigated the role of ginsenoside Re (Re) in preventing 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced apoptosis of the substantia nigra neurons in the mouse model of Parkinson's disease (PD). C57BL mice have been administrated i.s.c. with MPTP to establish the PD model. Pretreatment groups were given different doses of Re (6.5, 13,(More)
The effect of (3,5,6-trimethylpyrazin-2-yl)methyl 2-[4-(2-methylpropyl)phenyl]propanoate (ITE) on type II collagen (CII)-induced arthritis in mice was studied. Mice were immunized twice with CII, ITE being given orally once a day for 40 d after the 1st immunization. Clinical assessment showed that ITE had no effect on the day of onset of arthritis but did(More)
Two new 27-hydroxyoleanolic acid type triterpenoid saponins were isolated from the rhizomes of Anemone raddeana Regel. The structures of the two compounds were elucidated as 27-hydroxyoleanolic acid 3-O-beta-D-glucopyranosyl (1 --> 2)-alpha-L-arabinopyranoside (1) and 3-O-alpha-L-rhamnopyranosyl (1 --> 2)[beta-D-glucopyranosyl (1 -->(More)
