    Triptolide

    Preparation of Triptolide.

    Lei Gongteng herb 300 kg (tested, the content of its Lei Gongteng methylin 0.0043%), crushed to 20 ~ 30 mesh, loaded into the extraction tank, add 3 tonnes of ethyl acetate, and then add 360g of ascorbic acid, heated reflux extraction for 3 times, each time for 5 hours, the extract was filtered, concentrated under pressure to obtain the extract 8.3 kg;

    Dissolve the extract with 360 litres of dichloromethane, hit the extraction tank, another 17.28 kg of NaOH weighing, the preparation of 720 litres of 0.6moL/L NaOH solution, hit the extraction tank in 2 times, the dichloromethane dissolution of alkaline wash 2 times, concentrated dichloromethane phase to get alkaline wash after the extract 2 kg;

    Take 10 kg of 200-300 mesh Qingdao Ocean column chromatography orthophase silica gel, wet packing diameter 35 cm column, alkali wash after the paste on the sample first eluted with dichloromethane, to be eluted after the eluent colour becomes light, with dichloromethane: methanol = 50:1 mixed solvent elution for 2 column volumes, and then eluted with methanol, concentration of the methanol eluent to obtain methanol eluent 427g;

    Take 20 kg of 200-300 mesh Qingdao Ocean column chromatography orthophase silica gel, wet packing diameter 50 cm column, methanol eluent on the sample after the gradient elution with petroleum ether: ethyl acetate = 10:1, 6:1, 4:1, 2:1, 1:1 (v/v) mixed solvents in turn, each ratio elution of about 8 column volumes, collect the eluent containing tretinoin, concentrated to about 1/8 volume after 4 After concentrated to about 1/8 volume and static precipitation at 4 ℃, 13.8 g of crude tretinoin was obtained;

    The crude product was recrystallised with isopropyl ether as the crystallisation solvent at room temperature, and 12.3g of pure tretinoin was obtained by filtration after crystallisation, and its purity was 99.4% by HPLC.
