Objective: To investigate the factors influencing on the ephedrine contents in different compositions of Maxingshigan decoction.
Method: Adopt mixed uniform design to dismantle recipes, employ the stepping regression analysis to deal with experimental statistics, use the partial correlational analysis to analyze the correlation coefficients and the results were validated.
Result: The regressive equation was of significance, that is Y = 4.
Objective: To determine the contents of amygdalin in traditional and granular decoctions of Maxingshigan decoction.
Methods: The determination was carried out by HPLC with an ODS column and a mobile phase of water-methanol (23:77) at 215 nm.
Results: The content of amygdalin in traditional decoction of Maxingshigan Decoction was 17.
Objective: To investigate the contents of glycyrrhizic acid in hejian decoction (mixed the traditional Chinese herbs together, then boiling them with water) and the fenjian decoction (boiling the single traditional Chinese herb with water separately, then mixed the abstracts) of Sanaotang (composed of Ephedra sinica, Prunus armeniaca and Glycyrrhiza uralensis) and to compare with their anti-bacterial activities in vitro.
Method: A HPLC method was established with a Agilent Zorbax SB-C18 column (4. 6 mm x 250 mm, 5 microm), a mobile phase of acetonitrile-0.
Objective: To compare the contents of baicalin in the raw medical material and the different prepared medical materials of Scutellaria baicalensis.
Method: The contents of baicalin were determined by HPLC. Chromatographic conditions included Hypersil C18 column and the mobile phase consisting of a mixture of methanol-0.
