Method for extracting, separating and preparing lignin monomers from schisandra chinensis

The invention discloses a method for extracting, separating and preparing lignin monomers from schisandra chinensis. The method comprises the following steps: performing supercritical extraction on schisandra chinensis medicinal powder by using CO2 to obtain a crude extract; performing primary high-speed counter-current chromatographic separation on the crude extract; forming a solvent system A by using hexane, ethyl acetate, methyl alcohol and water in the volume ratio of (2-10):(0-10):(0-10):5, wherein the upper phase A is a stationary phase A and the lower phase A is a mobile phase A; preparing a first schizandrol, a second schizandrol and a third schizandrol; recovering the separated stationary A to serve as a sample to be tested; performing secondary high-speed counter-current chromatographic separation; forming a solvent system B by using hexane, ethyl acetate, methyl alcohol and water in the volume ratio of (1-10):(0-4):(0-9):1, wherein the upper phase B is a stationary phase B, and the lower phase B is a mobile phase B; preparing deoxyschizandrin and schisandrin b. By adopting the method which integrates supercritical extraction and high-speed counter-current chromatographic separation, the deoxyschizandrin and the schisandrin b can be directly used for separating and purifying subsequent monomers without complex sample treatment after the extraction; the steps of extracting and separating are simple and efficient.

The invention relates to a method for evaluating quality of FRUCTUSSCHISANDRAE SPHENANTHERAE in commercially available Chinese patent medicines by using a flash-gas chromatography. The method comprises the steps of putting a powdered or liquid Chinese patent medicine sample, which contains the FRUCTUSSCHISANDRAE SPHENANTHERAE, into a pyrolyzer, and placing the pyrolyzer at a sample inlet of a gas chromatograph; when the temperature of the pyrolyzer reaches a certain value, carrying out sample introduction; detecting the sample by using the gas chromatograph to obtain a gas chromatogram; carrying out qualitative analysis on a lignan component in the Chinese patent medicine sample by using standard material retention time, and determining the corresponding peak positions of anwuligan, deoxyschizandrin and schisantherin in the gas chromatogram; (2) then, using the flash-gas chromatography to carry out quantitative analysis on the deoxyschizandrin and the schisantherin in the Chinese patent medicine sample by means of an external standard method; if the quantitative result shows that the relative contents of the deoxyschizandrin and the schisantherin in the Chinese patent medicine sample are within a range of 1.50-2.0, proving that the quality of the FRUCTUSSCHISANDRAE SPHENANTHERAE in the Chinese patent medicine sample is better, and otherwise, proving that the quality of the fructus schisandrae in the Chinese patent medicine sample is poorer. The method has the characteristics of being simple, environmentally friendly and efficient.

Method for carrying out simultaneous quantitative analysis on four lignan components in Chinese magnoliavine raw material and Chinese magnoliavine extract

InactiveCN102419350ARealize simultaneous measurementSolve the problem that the raw materials of Schisandra chinensis cannot be measured at the same timeComponent separationLignanColumn temperature
The invention discloses a method for carrying out simultaneous determination on contents of schisandrin, schisantherin, deoxyschizandrin and schisandrin B in a Chinese magnoliavine raw material or a Chinese magnoliavine extract. The method employs means of crushing, sieving, methanol ultrasonic extraction, calibrating volume and filtering to treat schisandra chinensis or a Chinese magnoliavine extract to obtain a sample solution for testing; a high performance liquid chromatography is utilized for simultaneous determination on contents of four lignan components. The method utilizes a reverse direction distribution chromatographic theory to carry out analysis on the sample by gradient elution, under conditions of a column temperature of 25-45 DEG C, mobile phases of methanol and 0.05-0.2% trifluoroacetic acid aqueous solution (methanol and trifluoroacetic acid aqueous solution in a volume ratio of 50:50-100:0), an elution time of 30-60 min, a flow velocity of 0.7-1.5 ml / min and a detection wavelength of 210-280 nm. The quality detection method is simple, rapid, sensitive and accurate.

Application of Schisandra sphenanthera Rehd.et Wils. extract in preparation of medicament for treating liver injury caused by acetaminophen

The invention discloses an application of a Schisandra sphenanthera Rehd.et Wils. extract in preparation of a medicament for treating a liver injury caused by acetaminophen (APAP). The main ingredients of the Schisandra sphenanthera Rehd.et Wils extract are schisantherin and deoxyschizandrin. Experiments find that the Schisandra sphenanthera Rehd.et Wils. extract can significantly resist serum ALT (alanine aminotransferase)and AST (aspartate amino transferase)level rise and necrosis of liver cells caused by the liver injury caused by APAP, and inhibits consumption of reductive glutathione in the liver cells, so as to relieve the liver injury degree caused by the APAP. The mechanism relates to activation of an Nrf2-ARE (NF-E2-related factor 2-antioxidative responsive element) signal channel, is manifested by raising mRNA (messenger Ribonucleic Acid) expression of Nrf2, facilitating Nrf2 nuclear translocation, starting a downstream medicament-metabolizing enzyme and transcribing an antioxidant gene. The experiment result shows that the Schisandra sphenanthera Rehd.et Wils. extract has a treatment effect on the liver injury caused by the APAP, and novel method and means are provided for clinical prevention and treatment of the liver injury caused by the APAP.
