Embodiment 1
[0114] Embodiment 1: A kind of preparation method of the antitumor compound extracted from gecko, the derivative of general formula (I) is the compound shown in general formula (II), comprising the following steps:
[0115] (1) Purification process: store the captured live geckos for 24-72 hours to digest and drain the existing food and waste in the body, wash with distilled water, and dry;
[0116] (2) Pulverization process: the gecko after the purification is transferred to the soaking tank, and the ethanol solution is added. The ethanol solution has a concentration of 95% by volume and is soaked. After soaking the gecko to death, the gecko and the soaking solution are transferred to In the high-speed crushing machine, the crushing liquid is obtained;
[0117]The volume percent concentration of the ethanol solution in the above steps is 95%. It has been proved by experiments that under the premise that other process conditions and steps remain unchanged, the volume percent c...
Embodiment 2
[0137] Embodiment 2, the compound shown in general formula (II), comprises the following initial purification and purification steps:
[0138] (6.1) Initial purification process of chromatographic samples:
[0139] Add purified water to the crude extract prepared in Example 1, fully dissolve it, let it stand for stratification, and obtain an aqueous solution with a concentration of 1.0 g / mL, take the supernatant, and carry out chromatographic separation. The sample is concentrated by vacuum distillation, the pressure is controlled below -0.096Mpa, the temperature is controlled at 40 ° C ~ 50 ° C, after concentration, it is freeze-dried, the pressure of freeze-drying is controlled at -0.099 ~ -0.100Mpa, and the temperature is controlled at -45 ° C ~-55°C, freeze-dried to obtain the primary purification chromatography sample;
[0140] (7) High performance liquid chromatography process:
[0141] a. Add pure water to the prepared primary purification chromatography sample, fully...
Embodiment 3
[0148] Embodiment 3. This embodiment provides another preparation method different from that of Embodiment 2. The compound represented by the general formula (II) includes the following initial purification and purification steps:
[0149] (6.2) High performance liquid chromatography initial purification process:
[0150] a. After fully dissolving the crude extract obtained in Example 1, let it stand for stratification to obtain an aqueous solution with a concentration of 1.0 g / mL, discard the insoluble solids, take the supernatant, and use a 0.45 μm microporous Injection after membrane filtration;
[0151] b. The filtrate was subjected to HPLC semi-preparative C18 column chromatography. The chromatographic conditions were: column temperature: 35°C, mobile phase: pure water and acetonitrile, C18 filler as the stationary phase, detection wavelength: 210nm, and ultraviolet spectrum wavelength range: 200~380nm, gradient elution: 0~5min, the ratio of acetonitrile is 0~0%, 5~10min...
