Embodiment 1
[0024] Example 1 Extraction and Preparation of Tibetan Panmangosteen Volatile Oil
[0025] Take the dry whole herb of Tibetan flat mans chrysanthemum (W. glabra), pulverize it with a traditional Chinese medicine grinder, pass it through a (40 mesh) sieve, weigh 100 g, and soak it in distilled water overnight. According to the "National Pharmacopoeia of the People's Republic of China 2010 Edition Appendix XD" volatile oil determination method extraction 4h, get 1.5% light yellow essential oil;
[0026] Carry out chemical composition analysis according to " Chinese National Pharmacopoeia 2010 edition appendix XD " volatile oil determination method; Adopt gas chromatography-mass spectrometry detection (GC-MS) analysis, chromatography-mass spectrometry analysis condition is as follows:
[0027] Detection instrument: American Thermo DSQ gas chromatography-mass spectrometer;
[0028]Chromatographic conditions: Hp-5MS capillary column (5% phenyl methyl siloxane, 30m×0.25mm×0.25μm) c...
Embodiment 2
[0033] Example 2 Screening experiment of anti-influenza virus activity of volatile oil of chrysanthemum chrysanthemum
[0034] Detect the volatile oil of Tibetan chrysanthemum chrysanthemum made by MTT method to MDCK cytotoxicity, and CPE method (cytopathic) detects that the volatile oil of Tibetan chrysanthemum chrysanthemum is to influenza A virus A3 (H3N2) (A3 / Jingke) of influenza virus type A / 30 / 95) (purchased from Shanghai Center for Disease Control and Prevention), inhibitory effect, using ribavirin as positive control experiment:
[0035] First, the cytotoxicity test of the drug was carried out. After the MDCK cells were cultured in the cell culture plate to form a monolayer, different concentrations of the drug solution were added to continue the culture. The cytopathic or MTT staining method was used as the observation index, and the drug effect was calculated by the Reed-Muench method. The maximum concentration at which cells are not toxic (TD 0 ) and the median to...
Embodiment 3
[0039] Example 3 Screening experiment of anti-inflammatory activity of volatile oil of Tibetan chrysanthemum chrysanthemum
[0040] LPS and PolyI:C were used as stimulants to activate the TLR4 and TLR3 receptors of the macrophage cell line RAW264.7, triggering the downstream inflammatory response, and evaluating the anti-inflammatory effects of volatile oils induced by LPS and Poly IC by detecting NO in the cell supernatant The strength of the ability:
[0041] RAW264.7 cells were digested and counted according to 4*10 5 / ml seed plate, prepare 1mg / ml stimulant, 1mg / mlLPS stock solution, 100uM DEX stock solution and 0.5mg / ml volatile oil stock concentration (preparation concentration: 8, 40, 200ug / ml final concentration: 4, 20, 100ug / ml); prepare stock solution concentration: 0.5mg / ml, DMSO: 1:800, add the plate and place it in a cell incubator for culture, then take out and collect the supernatant (180ul / well) for determining the secretion of relevant inflammatory mediator ...
