North American jaundice alkaloids

Extraction source: This product is the north American of the hairy plant, the yellow Hydrastiscanadensis Lroot extracted alkaloids, the total alkaloid content of 80%main ingredient: small carmine Berberine, content: 40%"by-components" North American jaundice Hydrastinesmall coriatorberastineCanadine Canadinecontent: 40% " characteristics" this product is yellow to dark yellow powder, soluble in methanol, hot water, acetone"Identification" take this product with methanol to make 0.5% solution for test ingeTake the standard product small carnitine, small carnitine, North American jaundice, cannadin plus methanol to make each containing 1 mg / ml of solution as a control solutionTake the North American yellow company standard control medicine 0.5g plus methanol 5 ml, ultrasonic vibration up for 10 minutes, filtration, as a control fluidTake the above three liquids each 2 sl, respectively, point on the same silicone G board, to cyclhexane-ethyl-ethyl-isopropanol-methanol-water-triethylamine (3:3:5:1:1:0:5:1) unfolded, in the UV lamp 365nm inspection, the corresponding position shows the same color fluorescent spots, with the control of the drug, the corresponding rate of speckles of 80%Dry weightlessness: No more than 5.0% (Appendix IX.G)Burning Residue: No more than 0.8% (Appendix IX.J)Heavy Metals: No more than 10ppm (Appendix IX.E)"Content Determination" measured by high-efficiency liquid chromatography (Appendix VI.D) to determinechromatography condition C18mobile phase: acetylene-0.05mol/L potassium dihydrophosphate solution (50:50) (0.4g per 100ml plus sodium sulphate of twelve alkyl sulfate, and then pH-4.0 with phosphoric acid) detection wavelength: 345nm The number of theory boards is 5000 control fluid: refined hydrochloric acid small argon-based alkali plus methanol to make 1 ml containing 90.05 sg solution backup for test ingress: Semen-based with methanol is made into 1 ml with 180 sg solution backup the determination method: take the above two liquid 10 sl, respectively injected into the liquid chromatography, and calculate the total alkaloid content with small carbapenems " function" antibacterial, anti-inflammatory, sedative, bile, lower blood pressure, excited uterine storage is cool, dry and light-proof
