Embodiment 1
[0023] Embodiment 1, the research of the method for measuring ergosterol content in Ganoderma lucidum spore oil by high performance liquid chromatography
[0024] (1) Instruments and samples
[0025] Instruments: Agilent 1100 high performance liquid chromatography, DAD detector, quaternary gradient pump, G2170AA data processing software system (USA). Methanol was chromatographically pure, water was ultrapure water, and other reagents were analytically pure.
[0026] Samples: The reference substance ergosterol was provided by sigma; Ganoderma lucidum spore oil was provided by Guangzhou Hanfang Modern Chinese Medicine Research and Development Co., Ltd.
[0027]Preparation of the test solution: Accurately weigh 1g of Ganoderma lucidum spore oil, add 10ml of petroleum ether to dissolve it, add it on a silica gel column (100-200 mesh, 10g, inner diameter 15mm), use petroleum ether: ethyl acetate as 90: 10 solution 100ml elution, discard the eluent, and then use petroleum ether: e...
Embodiment 2
[0053] Embodiment 2, determination of ergosterol content in Ganoderma lucidum spore oil
[0054] According to the method for content determination of the above-mentioned Example 1, the content of ergosterol in 10 samples of Ganoderma lucidum spore oil was determined, and the results are shown in Table 6.
[0055] sample
[0056] The content of ergosterol in every 1g of Ganoderma lucidum spore oil is measured to be between 0.423-1.920mg.
Embodiment 3
[0057] The content determination of ergosterol in embodiment 3, Ganoderma lucidum spore oil emulsion
[0058] Determination by high performance liquid chromatography:
[0059] Chromatographic conditions and wavelength selection Octadecyl bonded silica gel is used as filler; methanol is used as mobile phase; detection wavelength is 280nm. The number of theoretical plates is calculated according to the ergosterol peak and should not be less than 2000;
[0060] Preparation of reference substance solution: take an appropriate amount of ergosterol reference substance, add methanol to make a solution containing 0.08mg per 1ml, and obtain the reference substance solution;
[0061] Preparation of test solution: Accurately weigh 10 g of ganoderma lucidum spore oil emulsion, add 2 g of anhydrous sodium sulfate, heat on a water bath to rupture the emulsion, transfer to a separatory funnel, extract 3 times with ether, 20 ml each time, combine Diethyl ether solution, evaporated to drynes...
