Jigucao capsule is a well‐known Chinese patent medicine for the treatment of acute and chronic hepatitis and cholecystitis. The chemical components of Jigucao capsule were not clear resulting from the paucity of relevant studies, which hindered the research of the pharmacological mechanism, the comprehensive development, and utilization of Jigucao capsule in clinical studies. By establishing a high‐throughput ultra‐performance liquid chromatography quadrupole time of flight mass spectrometry in combination with intelligent UNIFI software data processing platform to automatically characterize and identify the chemical profile of Jigucao capsule, 144 compounds were determined rapidly, including 34 terpenoids, 25 flavonoids, 22 steroids, 21 phenylpropanoids, 10 glycosides, six alkaloids, 13 organic acids, and other 13 components. These compounds may be the active components of Jigucao capsule. In this study, a rapid and robust method for comprehensively analyzing the chemical composition of Jigucao capsule was described and established for the first time. The results will provide a reference for the quality control of Jigucao capsule and the establishment of a higher quality standard, as well as for the pharmacodynamic material basis research.
Background
Illicium verum is widely cultivated in southern
China especially in Guangxi province. Its fruits has been traditionally used in
Chinese medicine. In recent years, it has been the industrial source of shikimic
acid. Usually the residues after extracting shikimic acid are treated as waste.
Thus, the aim of this study was to optimize the extraction conditions of
cellulase-ultrasonic assisted extraction technology for flavonoids from I. verum residues.ResultsThe optimum extraction conditions with a maximum flavonoids yield of
14.76 % are as follows: the concentration of ethanol is 51.14 %, the liquid–solid
ratio is 20.52 mL/g, the enzymatic hydrolysis pH is 5.303, the sonication time is
60 min, the enzyme solution temperature is kept at 45 °C, the amount of added
enzyme is 70 mg/g, the enzymatic hydrolysis time is 2 h and the crushed mesh size
is 0.355–0.85 mm.ConclusionsThe data indicate that the cellulase-ultrasonic assisted extraction
technology has the potential be used for the industrial production of flavonoids
from I. verum.
Dampness-heat Jaundice Syndrome (DHJS) is a complex Chinese medicine syndrome, while Jigucao capsule (JGCC) is an effective compound preparation of Chinese medicine for the treatment of DHJS about liver and gallbladder, but its mechanism is not clear yet. The purpose of this study is to clarify the pathogenesis of DHJS and the treatment mechanism of JGCC. We used ultra-high performance liquid chromatography/mass spectrometry (UPLC/MS) combined with pattern recognition, accompanied the advanced software and online database for the urine metabolomics of rats. The potential biomarkers disturbing metabolism were identified and the metabolic pathway was analyzed. We investigated the callback of biomarkers after treatment with JGCC. Finally, A total of 25 potential urine biomarkers were identified, including Arachidonic acid, Phenylpyruvic acid, L-Urobilin and so on, and 14 related metabolic pathways were disturbed. After treatment with JGCC, the clinical biochemical indexes and histopathological were significantly improved, and the disturbed biomarkers were also obviously adjusted. It is proved that JGCC has remarkable effect on the treatment of DHJS.

The death toll associated with cancer worldwide is constantly on the increase. Efforts to combat and treat the
different forms of this disease is also evolving. Nasopharyngeal carcinoma (NPC) is a lethal form of cancer which is
prevalent in Southern China that is normally treated by using radiotherapy. Here we review products obtained from natural
sources that have potential cytotoxic and apoptotic properties against NPC. These include grifolin, dihydroartemisinin,
luteolin, honokiol, indole-3-carbinol, caffeic acid phenethyl ester, 6-O-angeloylenolin, cucurbitacin E, genistein, helenalin,
celastrol, coronarin D, quercetin, trans-cinnamaldehyde, 5'-epimer episilvestrol, silvestrol, arnicolide D, brevilin A and
baicalin hydrate. Ethyl acetate extracts of Wedelia chinensis and aqueous extracts of Ajuga bracteosa are also included
although the bioactive compounds involved have yet to be identified. The known mechanism of action of these products are
discussed. It is anticipated that one or more of these substances may provide the general population with alternative and cost
effective ways to combat this fatal disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
