1. (+)-Catechin hydrate has antioxidant activity and is effective in reducing oxidative stress.
1. Corynoline is an acetylcholinesterase inhibitor.
1. Lyoniresinol shows robust anti-melanogenic activity, decreases tyrosinase activity and melanin biosynthesis in B16F10 cells by activating ERK signaling, which downregulated MITF, tyrosinase, but not TRP-1 and TRP-2 protein expression.
2. Lyoniresinol has antioxidant effect.
1. (+)-Praeruptorin A and (-)-praeruptorin A exerted distinct relaxant effects on isolated rat aorta rings, which might be mainly attributed to nitric oxide synthesis catalyzed by endothelial nitric oxide synthase.
1. (+)-Pteryxin has muscle-relaxant props.
2. (+)-Pteryxin shows hepatoprotective and nitric oxide prodn. inhibitory activity.
1. Taxifolin inhibits the cellular melanogenesis as effectively as arbutin.
2. Taxifolin inhibits the ovarian cancer cell growth in a dose-dependent manner.
3. Taxifolin inhibits cholesterol synthesis in a dose- and time-dependent manner.
4. Taxifolin is an important natural antioxidant in Russia, used in both the medical and food industries.
1. 20S, 20R ginsenoside-Rh1 can inhibit the thrombin-induced conversion of fibrinogen to fibrin.
1. (20S)-Protopanaxatriol shows strong and selective antimicrobial activity.
2. (20S)-Protopanaxatriol is the inhibitor of farnesyl-protein transferase.
3. (20S)-Protopanaxatriol exerts cardioprotective effects against myocardial ischemic injury, by enhancing the anti-free-radical actions of heart tissues.
4. (20S)-Protopanaxatriol has anti-oxidant activity, can inhibit the elevation of malondialdehyde content, the reduction of superoxide dismutase activity, glutathione peroxidase and total antioxIdant capacity.
1. 20S-protopanaxdiol saponins (PQDS) injection can obviously improve the ECG in Pit-induced AMI rats, alleviate the degree of cardiamyopathy in Iso-induced AMI rats, may via effect on AMI and anti-lipid peroxidation.
2. PQDS estrain the release of antistreptokinase (ASK), CK and lactate dehydrogenase (LDH), increase the activity of SOD and decrease the content of MDA.
3. PQDS has the effect of anti-tumor through increasing the activity of body immunity,improving the lymphocyte transformation,the activity of NK cells and the contents of IL-2 significantly.
