Embodiment 1
[0040] The preparation of embodiment 1 macrocyclic polyphenol compound
[0041] (1) Extraction and preliminary separation of herbal medicines
[0042] Grind 5kg of root vegetables, extract three times with 70% ethanol under hot reflux, each extraction time is 1 hour, add 15L of liquid each time, combine the extracts, concentrate under reduced pressure (55°C) until there is no alcohol smell to obtain the crude extract extract (relatively The density is 1.12~1.18), and its weight is 625g, and the yield is 12.5%. Then water (650ml) was suspended and passed through a macroporous resin column (D-101), followed by elution with water, 10% ethanol, 20% ethanol, 30% ethanol, 50% ethanol, 70% ethanol and 95% ethanol. The liquid is 10 to 12 times the volume of the column, and the eluents of water, 10% ethanol, 20% ethanol, 30% ethanol, 50% ethanol, 70% ethanol and 95% ethanol are respectively obtained, and concentrated under reduced pressure (55°C) to The extracts (relative density: 1....
Embodiment 2
[0049] Example 2 Determination of Macrocyclic Polyphenol Compounds 1-4 in Rhizoma Rhizoma Medicinal Materials
[0050] Its method and operation steps are as follows
[0051] (1) HPLC conditions
[0052] Chromatographic column: Diamonsil C18column (4.6mm×250mm, 5μm, Dikma);
[0053] Mobile phase: Gradient elution, A phase is acetonitrile, B phase is 0.2% formic acid aqueous solution;
[0054] Flow rate: 1.0ml / min, running time 70min, detection wavelength 280nm,
[0055] The column temperature is 25°C; the injection volume is 10 μl;
[0056] Table 1 Gradient elution program
[0057]
[0058]
[0059] (2) Content determination of compound 1-4
[0060] Take the compound 1-4 reference substance (prepared in Example 1), weigh it accurately, and prepare compound 1-4 solutions containing 350 μg, 100 μg, 200 μg, and 50 μg in each 2 mL with 60% methanol, respectively, as the reference solution.
[0061] Take an appropriate amount (equivalent to 10 g of the root vegetable) of...
Embodiment 3
[0062] Example 3 Compound 1-4 Hypoglycemic Activity Experiment in Vitro
[0063] 1 Materials and methods
[0064] 1.1 Test drugs
[0065] Embodiment 1 prepares gained monomer compound 1-4
[0066] Experimental Materials
[0067] Acarbose (Bayer, 50mg / tablet, commercially available), glucose detection kit (glucose oxidase-peroxidase method, Shanghai Rongsheng Biotechnology Co., Ltd.), α-amylase (Wako Pure Chemicals Ind., Osaka, Japan), microplate reader (EIx800, Biotek), 96-well cell culture plate (Corning / Costar)
[0068] 1.2 Experimental method
[0069] 1.3.1 Chromogenic reagent: Dissolve 10.8 grams of sodium benzoate and 5 grams of potassium iodide in 400ml of water, then dilute to 500ml.
[0070] 1.3.2 Make 1-4 into 10mg / ml solution with DMSO (dimethyl sulfoxide), and then dilute with water to 0.556mg / ml, 0.185mg / ml, 0.062mg / ml, 0.020mg / ml and 0.007mg / ml respectively There are 5 different concentrations of mg / ml; the starch is prepared into a starch solution with a co...
