Wuweizi has been utilized as a sedative and tonic to treat various diseases such as chronic cough and dyspnea, nocturnal emission, spermatorrhea, enuresis, and frequent urination and could also be used as flavouring agent of foods. chinensis have been accepted as two different crude drugs, “Nan-wuweizi” (Fructus Schisandrae Sphenanthera) and “Bei-wuweizi” (Fructus Schisandrae Chinensis), which distributed in the southern provinces (Shanxi, Shaanxi, Gansu, Shandong, Jiangsu, etc.) and northern provinces of China (Heilongjiang, Jilin, Liaoning, Neimenggu, etc.), respectively. Since the 2000 edition of Chinese Pharmacopoeia, the fruits of S. chinensis (Turcz.) (Schisandraceae), is one of the most famous TCMs and has been widely used for thousands of years in China. įructus Schisandrae, the ripe fruits of Schisandra sphenanthera Rehd. Therefore, in recent years, there is an increasing trend to establish multicomponents analysis for the effective quality control of TCMs. There is no denying the fact that multicomponents of TCMs are responsible for the therapeutic effects by the multipath-assisted multitarget approach. Therefore, quality control of TCMs is becoming extremely urgent. However, the quality of TCMs had an important influence on its clinical efficacy due to their different species, harvest season, storage, and geographic origins.
This may be primarily because of the general belief that herbal drugs are without any side effect besides being cheap and locally available. Gradually, TCMs have been attracting interest and acceptance in many western countries. Traditional Chinese Medicines (TCMs) have made great contribution to the health of Chinese people for thousands of years due to its special clinical efficacy. Finally, these pharmacologically active constituents in the titled plant, schisandrins A–C and schizandrols A and B, were quantitatively determined using a validated GC-MS method. Meanwhile, relative peak areas may be a feasible approach to discriminate the S. The relative retention times of these characteristic peaks in the GC-MS fingerprint were established as an important parameter for identification of Schisandra samples. Five peaks were selected as characteristic peaks, and all of these were identified by using GC-MS techniques. The GC-MS fingerprints of 15 batches of Schisandra samples from different regions of China showed similar lignan profiles. The method was established by using specific lignan fingerprint profiles and quantitation of characteristic compounds in this herbal medicine. For fingerprinting, the report emphasized the potential for automating fingerprint analysis, to potentially reduce bias in interpreting match results when fingerprints at a scene are smudged or otherwise unclear.This paper describes a simple, rapid, and effective quality assessment method for Fructus Schisandrae by gas chromatography-mass spectrum (GC-MS). A recent report prepared by the President’s Council of Advisors on Science and Technology (PCAST) makes strong recommendations for improving the scientific basis of forensic evidence used in the courtroom. Recent wrongful convictions and scientific studies of forensic methods have increased scrutiny of the validity and reliability of several forms of forensic evidence, including fingerprints. However, inadequate proficiency testing of investigators has led to inaccurate interpretations of the evidence. Officers often rely on chemical techniques, such as those above, to visualize the evidence. Individual fingerprint identification records have also been used in sentencing, probation, and parole decisions. Investigators use fingerprints to link a perpetrator to a crime scene. Law enforcement has relied on fingerprint analysis to identify suspects and solve crimes for more than 100 years.
