[0007] The preparation method of the present invention is as follows:
[0008] One, the preparation method of extracting 7,16-pimarinadienoic acid from Torreya aril:
[0009] 1. Extraction: after crushing, the aril of Torreya torreya is soaked with 5-8 times the amount of petroleum ether, percolated for 3 times, and then the dregs are extracted by percolation with 10 times the amount of 85% ethanol, and the extract is recovered to obtain the extract. After suspending the ointment with 2 times of water, extract 5 times with an equal amount of ethyl acetate, combine the ethyl acetate extracts, recover the solvent under reduced pressure, and obtain the ethyl acetate extract.
[0010] 2. Separation: carry out silica gel column chromatography on ethyl acetate extract, carry out gradient elution with petroleum ether: ethyl acetate = 9: 1 ~ 7: 3, thin-layer detection, collect the fraction containing the chemical component, and then pass through Purified by Sephadex LH-20 column chro...
Embodiment 1
[0032] Embodiment 1: the preparation of 7,16-pimaric dienoic acid
[0033] Take 6 kg of Torreya sinensis from Zhejiang, soak in 30 liters of petroleum ether for 3 days, then infiltrate, use 60 kg of 85% ethanol to extract the dregs, collect the ethanol leachate, recover under reduced pressure, and obtain 1.3 kg of ethanol extract , the extract was suspended with 2.6 kg, extracted with an equal amount of ethyl acetate to obtain an ethyl acetate extract, and the ethyl acetate was recovered under reduced pressure to obtain 620 grams of extract.
[0034] The above-mentioned extract was subjected to silica gel column chromatography, and about 30 liters of petroleum ether: ethyl acetate (9: 1 ~ 7: 3) was used for elution, and every 200 milliliters was 1 fraction, and the 110th to 130th fractions were combined and subtracted. The solvent was recovered under pressure, and the residue was subjected to gel Sephadex HL-20 column chromatography, and eluted with 5 liters of dichloromethane...
