Embodiment 1
[0049] First, extract the active ingredient 8-hydroxy-2-methoxy-1,4-naphthoquinone:
[0050] (a) Make 28kg of walnut bark into a vermicelli shape, place it in a 30L stainless steel reaction kettle, add about 90kg of 95% industrial alcohol, control the temperature at about 50°C to 60°C, stir mechanically, and extract twice, the first time 2 hour, and 1 hour for the second time. Use a centrifuge to separate, combine the extracts, and discard the residue;
[0051] (b) the extract is concentrated to a small volume with a self-made thin film evaporator, and then concentrated to no alcohol smell with a rotary evaporator to obtain extract A;
[0052] (c) sequentially extracting with petroleum ether, ethyl acetate, and n-butanol, and recovering the solvent, to obtain petroleum ether extract B, ethyl acetate extract C, and n-butanol extract D;
[0053] (d) Take about 100g of ethyl acetate extract extract, and use Na 2 CO 3 After the aqueous solution is dissolved, it is extracted wi...
Embodiment 2
[0058] The process of extracting the active ingredient 8-hydroxy-2-methoxy-1,4-naphthoquinone is the same as that in Example 1.
[0059] Afterwards, antineoplastic drugs are formulated:
[0060] Take 0.1g of the HT-12 crystal extracted in the previous step, and distilled water 99mL to prepare 100g injection according to the conventional method, which can be made into 20 injections according to the specification of 5mL each.
