Embodiment 1

[0020] Embodiment one: the preparation method of compound artoheteronin

[0021] A. The dried Jackfruit pulp (10.7kg, Hainan) was pulverized and extracted four times by cold soaking with 75% ethanol solution, each time for one week, filtered, and the filtrate was collected and concentrated under reduced pressure to obtain the ethanol extract;

[0022] B. The ethanol extract was added with distilled water to make a suspension, which was sequentially extracted with petroleum ether and ethyl acetate, and the petroleum ether extract was concentrated under reduced pressure to obtain 518.8 g of petroleum ether extract;

[0023] C. Purify the petroleum ether extract by column chromatography:

[0024] (1) The petroleum ether extraction extract was separated by silica gel column chromatography, and gradient elution was carried out with petroleum ether-ethyl acetate (volume ratios of 83:17, 68:32 and 55:45) as the eluent, and collected Petroleum ether-ethyl acetate (volume ratio 68:32)...

Embodiment 2

[0030] Embodiment two: the preparation method of compound artoheteronin

[0031] A. The dried jackfruit pulp (100.8kg, Hainan) was pulverized and then extracted four times by cold immersion in methanol, each time for one week, filtered, the filtrate was collected, and concentrated under reduced pressure to obtain a methanol extract;

[0032] B. The methanol extract was added with distilled water to make a suspension, which was sequentially extracted with petroleum ether and ethyl acetate, and the petroleum ether extract was concentrated under reduced pressure to obtain 5218.7 g of petroleum ether extract;

[0033] C. Purify the petroleum ether extract by column chromatography:

[0034] (1) Use silica gel column chromatography to separate the extract from petroleum ether, use petroleum ether-ethyl acetate (83:17, 68:32 and 55:45 by volume) as the eluent for gradient elution, and collect petroleum Ether-ethyl acetate (volume ratio 68:32) eluate;

[0035] (2) Take petroleum eth...

Description

technical field [0001] The invention belongs to the field of natural medicines, and in particular relates to a preparation method of an isopentenyl-substituted coumarin compound derived from jackfruit and having a novel chemical structure and its application in antitumor drugs. Background technique [0002] Malignant tumor is a frequently-occurring disease with a high mortality rate. It is currently seriously threatening human life and health, and is gradually becoming the number one killer of human life and health. The treatment of malignant tumors in modern medicine mainly includes surgical treatment, chemical drug therapy, radiotherapy and biological therapy, with chemical drug therapy as the main treatment. Even if surgical treatment is adopted, it is often necessary to routinely use chemical drugs for adjuvant treatment after surgery . With the rapid development of life sciences, the mechanism of malignant tumors has been elucidated, and new anti-tumor targets have bee...
