The invention discloses a quality detection method of a coptis-gardenia medicine pair. According to the quality detection method, analysis conditions such as optimal mobile phase composition, elution procedure, mass spectrum, flow velocity and chromatographic column are screened through a large number of experiments. The chemical components of the coptis chinensis-gardenia medicine pair are analyzed and identified by adopting a UPLC-Q-TOF / MS technology, 99 components are identified, 41 coptis chinensis and 60 gardenia are common, and alkaloids, phenylpropanoids, iridoids, organic acids and flavonoids are taken as main components. On the basis, the UPLC-PDA (Ultra Performance Liquid Chromatography-Personal Digital Assistant) technology is used for carrying out content determination on the main effect components of the coptis-gardenia medicine pair, such as genipin 1-O-gentiobioside, geniposide, coptisine, epiberberine, cotetrandrine, jateorhizine, berberine hydrochloride and palmatine hydrochloride. Systematic methodology investigation and content determination prove that the method is good in precision, stability and repeatability, and reliable technical support is provided for quality control of coptis chinensis-gardenia medicine pairs and basic research of pharmacodynamic substances.

The above-mentioned effective part for resisting pulmonary fibrosis is first discovered, the active ingredients are clear, the effect of treating pulmonary fibrosis is comprehensive, the effect of treating pulmonary fibrosis is obviously superior to that of the prior art, and the Nanshanhuagen extract can produce a synergistic effect with a chemical medicine for resisting pulmonary fibrosis. According to specific effective compounds in the above-mentioned extract, it is found that the compounds have a synergistic effect, and a corresponding medicine composition for treating pulmonary fibrosis is disclosed.

The application discloses a mutant of iridoid synthetase with improved specificity and enzyme activity and application thereof. The mutant of iridoid synthetase is obtained by mutation of wild-type iridoid synthetase NmISY2 derived from Nepeta mussinii. The mutant has higher catalytic activity to 8-oxogeranial, and the enzyme activity to geranial is obviously decreased. The ratio of the enzyme activity of the mutant to 8-oxogeranial and geranial is up to 293 times, which is greatly improved compared with the parent iridoid synthetase. The mutant can be used for heterologous synthesis and in-vitro synthesis of iridoid compounds and derivatives, and has a good application prospect.

The invention discloses an iridoid compound with anti-aging activity in rhododendron simsii as well as a preparation method and application of the iridoid compound, and belongs to the technical field of natural product chemistry. According to the present invention, the two iridoid compounds such as pacyodiridoid A and splendoside with anti-aging activity are separated from the rhododendron simsii for the first time, and the experiment results show that in the caenorhabditis elegans model, the two compounds can improve the physiological status of caenorhabditis elegans from multiple dimensions, can significantly improve the anti-oxidative stress ability of caenorhabditis elegans, and can provide the anti-aging activity for the caenorhabditis elegans, such that the anti-aging activity of the caenorhabditis elegans can be significantly improved, and the anti-aging activity of the caenorhabditis elegans can be significantly improved; the two compounds have obvious effects in the aspects of aging-related indexes (life, exercise ability and food intake) and growth and development indexes, fully prove that the two compounds have excellent anti-aging activity, lay a new material basis and theoretical basis for the research of an anti-aging mechanism, and open up a new direction for the development of novel anti-aging drugs at the same time.
