The present research was the first to evaluate acute and subchronic toxicity in experimental animals of(More)
OBJECTIVE To study the genetic diversity of rDNA ITS sequences in different species of Bai Shouwu, utilize the molecular diversity of ITS sequences to authenticate the different species of Bai Shouwu. METHOD Firstly, total DNA was extracted from the different species of Bai Shouwu. Secondly, the ITS sequence was amplified by PCR with universal primer of(More)
The present study was undertaken with the objective of finding out the comparative analgesic effect of Ligusticum chuanxiong (LC) pieces decoction, LC formula granule decoction, liquored LC pieces decoction and liquored LC formula granule decoction. The analgesic effects were analyzed using the hot plate and acetic-induced writhing test in mice, and(More)
Two sulfated derivatives (PRP-S1 and PRP-S2) of a β-glucan from Phellinus ribis with different degrees of substitution were obtained by chlorosulfonic acid method. The derivatives could block formation of new vessels in zebrafish and inhibit the proliferation of human umbilical vein endothelial cells (HUVECs). The two sulfated derivatives had remarkably(More)
OBJECTIVE To identify three groups of traditional Chinese drugs by electrophoresis finger-prints. METHODS The 3 groups of drugs of different species or varieties were analyzed by protein, peroxidase(POD) isozyme and esterase (ES) isozyme polyacrylamide gel electrophoresis, respectively. And their finger-prints were established. RESULTS Not less than one(More)
