Embodiment 1
[0033] A method for preparing an anti-tumor effective part of Hibiscus chinensis, comprising the following steps:
[0034] (1) Take the trunk of the hibiscus officinalis, dry it in the shade, and remove the miscellaneous trees; cut the hibiscus officinale into small sections, and crush it into 0.5-2cm;
[0035] (2) Use an organic solvent (dichloromethane) to heat and reflux for 6 to 12 hours, and reflux and extract 3 times;
[0036] (3) Filtrate to obtain the total extract of Hibiscus japonica, concentrate under reduced pressure until the fluid paste density is 0.9g / ml, to obtain the total extract;
[0037] (4) Take the obtained total extract, use silica gel dry method to mix the sample, after the organic solvent evaporates to dryness, grind it finely, use silica gel (200-300 mesh) column chromatography, use petroleum ether as eluent, elute 3 The petroleum ether part was obtained by the column volume, and then dichloromethane-methanol (40:1) was used as the eluent to elute fo...
Embodiment 2
[0040] A method for preparing an anti-tumor effective part of Hibiscus chinensis, comprising the following steps:
[0041] (1) Take the trunk of the hibiscus officinalis, dry it in the shade, and remove the miscellaneous trees; cut the hibiscus officinale into small sections, and crush it into 0.5-2cm;
[0042] (2) Use organic solvent (acetone) to extract by cold soaking for 24 hours, and extract 3 times;
[0043] (3) Filtrate to obtain the total extract of Hibiscus japonica, concentrate under reduced pressure until the fluid paste density is 1.2g / ml, to obtain the total extract;
[0044] (4) The obtained total extract was mixed with silica gel dry method, and after the organic solvent was evaporated to dryness, it was ground, and silica gel (200-300 mesh) column chromatography was used to elute 10 samples with petroleum ether as the eluent. The petroleum ether part was obtained by the column volume, and then dichloromethane-methanol (40:1) was used as the eluent to elute for...
Embodiment 3
[0047] The main difference between embodiment 3 and embodiment 2 is:
[0048] In step (5), when performing macroporous adsorption resin elution, the chromatographic column is sequentially filled with D101, D201 and D411 type macroporous adsorption resins (mass ratio is 4:1:2).
