Embodiment 1
[0043] A method for simultaneously determining six components in Xiangsha Yangwei Tablets, the specific steps are as follows:
[0044] Step S1, preparation of dehydrocresinide reference substance solution: accurately weigh 4.00 mg of dehydrocresinides reference substance, put it in a 10ml volumetric flask, add absolute ethanol to dilute to the mark, and mix well to obtain dehydrocresinides Fragrant lactone reference substance solution;
[0045] Step S2, preparation of the oleic acid reference substance solution: accurately weigh 3.01 mg of the oleic acid reference substance, put it in a 10ml volumetric flask, add absolute ethanol to dilute to the mark, and mix well to obtain the oleic acid reference substance solution;
[0046] Step S3, preparation of stearic acid reference substance solution: accurately weigh 10.01 mg of dehydrocresinolide reference substance, put it in a 10ml volumetric flask, add absolute ethanol to dilute to the mark, and mix well to obtain stearic acid re...

Abstract
The invention provides a method for simultaneously detecting six ingredients in elecampane and fructus amomi stomach-nourishing tablets. The method comprises the following steps: respectively weighingdehydrocostus lactone, oleic acid, stearic acid, magnolol, 4-O-methyl and magnolol, and magnolol, putting into a volumetric flask, adding absolute ethyl alcohol, and uniformly mixing to obtain a reference substance solution; precisely absorbing the reference substance solution into the volumetric flask, adding absolute ethyl alcohol, and uniformly mixing to obtain a mixed reference substance solution; finely grinding elecampane and fructus amomi stomach-nourishing tablets, precisely weighing, putting into a conical flask, adding absolute ethyl alcohol, performing ultrasonic treatment, uniformly mixing, and filtering with a filtration membrane; precisely absorbing the mixed reference substance solution and a test sample solution, injecting into a gas chromatograph, and detecting, wherein the chromatographic condition is carrier gas to nitrogen; the sample inlet has a temperature of 250 DEG C, a column oven has a temperature of 210 DEG C, a detector has a temperature of 280 DEG C, the carrier gas has a flowing speed of 3.0ml / min, the make-up gas is 30ml / min, the split ratio is 2:1, the air flow rate is 200ml / min, the nitrogen gas flow rate is 30ml / min, the sample amount is 1mu l, and the detector is an FID (Flame Ionization Detector) detector. The method is simple to operate, and the detection result is more accurate and more trustable.
Description
technical field [0001] The invention relates to the field of chemical drug quality detection, in particular to a method for simultaneously measuring six components in Chinese patent medicine Xiangsha Yangwei Tablets by using gas chromatography. Background technique [0002] The prescription of Xiangsha Yangwei Tablets is composed of woody fragrance, malt, tangerine peel, Atractylodes macrocephala, atractylodes rhizome, Magnolia officinalis, licorice, etc. It has the effects of invigorating the stomach and eliminating food, promoting qi and relieving pain, and is used for gastrointestinal weakness, indigestion, fullness of the chest and diaphragm , abdominal pain, vomiting, borborygmus and diarrhea. In Xiangsha Yangwei Tablets, the woody aroma can promote qi and relieve pain, invigorate the spleen and eliminate food. , is a ministerial drug, its main components are magnolol, 4-O-methyl honokiol, and honokiol, which have pharmacological effects such as antioxidant, antibacter...
