Isatis indigotica is a widely used herb for the clinical treatment of colds, fever, and influenza in Traditional Chinese Medicine (TCM). Various structural classes compounds have been identified as effective ingredients. However, little known at genetics level about these active metabolites. In present study, we performed de novo transcriptome sequencing first time to produce comprehensive dataset I. indigotica. A database 36,367 unigenes (average length = 1,115.67 bases) was generated by...

In the present study, anxiolytic and sedative-hypnotic activities of polygalasaponins extracted from Polygala tenuifolia Willdenow (Polygalaceae) were determined in mice using hole-board, elevated plus maze, open field, sodium pentobarbital-induced hypnosis tests. Moreover, acute toxicity was also estimated mice. Sixty minutes after p.o. administration (40, 80, 160 mg/kg) mice, central crossing counts percentage central/total ambulation significantly increased number rearings defecations...

The protective effects of Semen Hoveniae extract (SHE) from Hovenia dulcis Thunb. (Rhamnaceae) on acute alcohol-induced liver injury were investigated in vivo using mice as test models. In the present study, SHE (150, 300, 600 mg/kg/day) was given to by intragastric administration for 4 days. Mice gavaged with 60% ethanol 10 mL/kg after last dose extract. Six hours alcohol administration, evaluated biochemical examination. Lipid peroxidation and activity antioxidants measured...

1. Antithrombotic agents are effective in the treatment of ischaemic stroke. Timosaponin B-II (TB-II) is a major active component Anemarrhena asphodeloides Bunge (Liliaceae; rhizome) that has protective effects against cerebral damage. The present study examined antiplatelet and antithrombotic actions TB-II. 2. In vitro experiments, TB-II (20, 40 80 mg/mL) potently dose-dependently inhibited ADP-induced platelet aggregation. Furthermore, 1, 3 6 mg/kg prolonged activated partial...
