Embodiment 1
[0029] The preparation of embodiment 1 toosendan extract
[0030] Get 4 kg of Toosendan medicinal material, crush it into a coarse powder, and reflux extract it with 50 L of 75% ethanol for 3 times, each time for 2 hours, combine the extracts, recover the solvent under reduced pressure, and obtain 550 g of Toosendan extract, disperse it with 4 L of water, and use Ethyl acetate was shaken and extracted 4 times, 4 L each time, the ethyl acetate extracts were combined, and the solvent was recovered under reduced pressure to obtain Toosendan extract (180 g).
Embodiment 2
[0031] The separation and identification of chemical constituents in the extract of Toosendan in embodiment 2
[0032] Take Toosendan extract (100 g) obtained in Example 1, perform normal pressure silica gel column chromatography, petroleum ether (60-90° C.)-ethyl acetate system gradient elution, and obtain 140 fractions, which were detected by TLC and combined There are 10 components (F1~10). Using various adsorption materials such as silica gel, reversed-phase silica gel, gel, etc., through various separation methods such as normal pressure column chromatography, medium pressure column chromatography and high pressure liquid phase preparation technology, the compound is separated from F6 (Fr 87~92) 1 (51 mg) and compound 2 (14 mg); compound 3 (22 mg) was obtained from F5 (Fr 73-86); compound 4 (300 mg) was obtained from F8 (Fr 98-109).
[0033] MS, NMR and other data of compounds 1, 2 and 4 were confirmed as Nimbolin A (Nimbolinin A), Nimbolin B (Nimbolinin B) and 1-deacety...
