The invention provides a detection method of a medicament for treating angina pectoris. According to the detection method, ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1 in the medicament are detected by high performance liquid chromatography. Conditions of the high performance liquid chromatography comprise: octadecylsilane bonded silica gel is used as a chromatographic column for a filler; and an acetonitrile solution is used as a mobile phase A and water is used as a mobile phase B for gradient elution. The gradient elution process is as follows: during the first 25 minutes, the mobile phase A acetonitrile solution is 15% by volume and the mobile phase B water is 85% by volume; from the 25th minute to the 70th minute, the mobile phase A acetonitrile solution is 15-22% by volume and the mobile phase B water is 85-78% by volume; from the 70th minute to the 80th minute, the mobile phase A acetonitrile solution is 22-30% by volume and the mobile phase B water is 78-70% by volume; from the 80th minute to 105th minute, the mobile phase A acetonitrile solution is 30-40% by volume and the mobile phase B water is 70-60% by volume; and from the 105th minute to 120th minute, the mobile phase A acetonitrile solution is 40-15% by volume and the mobile phase B water is 60-85% by volume.

Wuji gastric floating sustained-release pellet and preparation method thereof

The invention relates to a pharmaceutical composition for treating liver-stomach disharmony, bitter taste, epigastric upset, vomiting, acid regurgitation, stomachache and dysentery, especially to an oral gastric floating pellet preparation prepared mainly on the basis of a set traditional Chinese medicine prescription. The pellet preparation is mainly composed of a lightweight drug-loaded pellet core and a retardant layer coating, wherein the lightweight drug-loaded pellet core comprises 10 to 15% of extract of a Wuji prescription, 0 to 20% of a filler, 60 to 65% of an adhesive, a skeletal material and a floating aid, 5 to 10% of a hydrophilic gel material and 5 to 10% of a floating sustaining agent, and the retardant layer coating comprises 90 to 95% of a coating material and 5 to 10% of an anti-adherent. According to the invention, a high-speed fusion and stirring method is employed to prepare a pellet; the prepared pellet floats upon entering water and continuously floats for 6 h, so drugs in the pellet are slowly released; the prepared pellet has the characteristics of a great distribution area, small local irritation, etc., and due to the floating characteristic of the pellet, retention time of the pellet in the stomach is substantially prolonged, which enables bioavailability of the drugs to be greatly improved; and since the high-speed fusion and stirring method is utilized to prepare the pellet, the advantages of easiness, economic performance and no risks of fire outbreak and explosion are obtained compared with a conventional wet-rolling preparation method.
