In this paper, the compatibility rationality of this decoction was investigated. Shaoyao–Gancao decoction, Shaoyao decoction and Gancao decoction were orally administered to rats, respectively. Blood(More)
OBJECTIVE To evaluate the analgesic and anti-migraine activities of senkyunolide I from Ligusticum chuanxiong. METHODS Mice were orally administered various doses of senkyunolide I, and their pain levels were assessed in a hot-plate test and by application of acetic acid. The levels of 5-hydroxytryptamine (5-HT), 5-hydroxytryptophan (5-HTP),(More)
OBJECTIVE To study the changes of the in vitro and in vivo material base of Shaoyao Gancao decoction (SGD) based on HPLC-DAD-ESI-MS, and confirm the migrational constituents in plasma. METHOD Kormasil C18, (4.6 mm x 250 mm, 5 microm with protection column) was employed; acetonitrile and 0.5% acetic acid/water was used as mobile phase for gradient elution,(More)
The two herbs Ligusticum chuanxiong (LC) Hort. (Umbelliferae) and Gastrodia elata (GE) Blume (Orchidaceae), are widely used in the clinic for the treatment of migraine. This article aims to understand the effects of LC and GE on blood-brain barrier (BBB) permeability in migraine rats. Serotonin, excitatory amino acids (EAAs) and matrix metalloproteinase-9(More)

OBJECTIVE To explore an HPLC method for determination of rhnchophylline and isorhnchophylline in Uncaria rhnchophylla. METHOD An HPLC method has been developed for determination of rhnchophylline and isorhnchophylline. The transformation of rhnchophylline and isorhnchophylline after heating was also studied by HPLC-ESI-MS. RESULT Good linearities of(More)
Preparative HPLC was used to prepare ferulic acid, senkyunolide I and senkyunolide H from Ligusticum chuanxiong. The separation was conducted on a Shim-Pack Prep-ODS (20.0 mm x 250 mm, 5 microm) column with the mobile phase of methanol-0.2% glacial acetic acid (50:50)at the flow rate of 5 mL x min(-1). The detection wavelength was 278 nm, and the purity of(More)
