Embodiment 1
[0057] Embodiment 1: the preparation of reference substance
[0058] 1. Preparation of the crude extract of Antrodia camphorata cultured in a dish
[0059] 1) After chopping Antrodia camphorata cultured in a dish, extract it to obtain an extract, wherein the extraction solvent is soaked in 25 L of methanol for overnight extraction, a total of 3 times, and the filtrate is obtained after filtration;
[0060] 2) The filtrate is concentrated under reduced pressure and then vacuum-dried to obtain the crude extract of Antrodia camphorata cultured in a dish.
[0061] 2. Preparation of monomeric compounds by silica gel column chromatography, ODS column chromatography and HPLC
[0062] 1) Dissolve the dish culture Antrodia camphorata crude extract (104.3g) with methanol (25mL) and dichloromethane (25mL) to obtain the methanol and dichloromethane solution of the dish culture Antrodia camphorata crude extract, mix the sample solution Put it into 200g of 80-100 mesh silica gel, and obta...
Embodiment 2
[0070] Embodiment 2: the establishment of quality control method
[0071] The present invention optimizes the HPLC fingerprint conditions of the test product, realizes the baseline separation of the epimers (25R)-Antcin K and (25S)-Antcin K for the first time, and the internal standard (25S)-Antcin C is difficult to The content of separated (25S)-Antcin K and (25R)-Antcin K was determined, and the external standard method was used to prove the reliability of the results again. It laid the foundation for the establishment of the quality standard of Antrodia camphorata cultured in dish culture.
[0072] The specific operation steps are as follows:
[0073] 1. Analysis of HPLC conditions
[0074] The mobile phase is a three-phase system of water (A), acetonitrile (B) and methanol (C), all of which are added with 0.2% acetic acid for gradient elution. The specific elution conditions are: 0-30min, 50%-44%A, 25%-28%B, 25%-29%C, flow rate 0.5mL / min; 30-60min, 36%-22%A, 38% ~63% B...
