Embodiment 1

[0057] Method for Determination of C21 Steroid Weight Percentage in Radix Radix C21 Steroid Extract by Colorimetry

[0058] Solution preparation

[0059] Preparation of reference solution

[0060] Accurately weigh an appropriate amount of nodolimonin reference substance, add methanol to make each 1 ml containing 198.72 mu g solution, as the reference solution.

[0061] Preparation of the test solution

[0062] Take 0.1 g of radish C21 steroid extract, weigh it accurately, add methanol to dissolve, transfer to a 50 ml measuring bottle, add methanol to the mark, shake well, accurately draw 10 ml, put it in a 100 ml measuring bottle, add methanol to scale, shake well, filter, and take the continued filtrate as the test solution.

[0063] Assay method

[0064] Precisely draw the test solution 100 mu l, put it in a stoppered test tube, evaporate the solvent, add 5 ml of freshly prepared concentrated sulfuric acid-methanol (6:1) precisely, shake well, put it ...

Embodiment 2

[0066] Take 100 Kg of dried cane powder of radish, add 8 times the amount of water to reflux and extract 3 times, each time for 2 hours, filter, combine the extracts, recover ethanol under reduced pressure to obtain the extract. Take the extract and dissolve it in water, add it to the HPD100 macroporous adsorption resin column, elute with water until the eluent is nearly colorless, discard the eluent, and elute with 10% ethanol until the eluent is nearly colorless, discard the eluent Remove the liquid, elute with 90% ethanol until the eluate is nearly colorless, collect the eluate, add the 90% ethanol eluate to the D941 decolorization resin column, elute with 6 times the column volume of 90% ethanol, collect the eluate liquid, concentrated under reduced pressure, and dried to obtain 1.47 Kg of Radix Radix C21 steroid extract, wherein the weight percentage of C21 steroid is 52%.

Embodiment 3

[0068] Take 100 Kg of dried cane powder of radish, add 8 times the amount of 30% ethanol to reflux and extract 3 times, each time for 2 hours, filter, combine the extracts, and recover the ethanol under reduced pressure to obtain the extract. Take the extract and dissolve it in water, add it to HPD300 macroporous adsorption resin column, elute with water until the eluent is nearly colorless, discard the eluent, and elute with 50% ethanol until the eluent is nearly colorless, discard the eluent Remove the liquid, elute with 60% ethanol until the eluate is almost colorless, collect the eluate, add the 60% ethanol eluate to the D941 decolorization resin column, elute with 6 times the column volume of 90% ethanol, collect the eluate liquid, concentrated under reduced pressure, and dried to obtain 0.46 Kg of Radix Radix C21 steroid extract, wherein the weight percentage of C21 steroid is 91%.

Abstract

The invention provides a metaplexis japonica C21 steroid extractive, and a preparation method and an application of the metaplexis japonica C21 steroid extractive. The metaplexis japonica C21 steroid extractive is characterized in that dry metaplexis japonica rattan is extracted by a 0-100% alcohol solution, metaplexis japonica C21 steroids are separated by macroporous adsorption resin and decolorizing resin methods, and the weight percentage of C21 steroids is 50-95%. Proven by a research on pharmacological activities, the prepared metaplexis japonica C21 steroid extractive has the functions of reversing multiple drug resistance of a tumor, and can be used for preparing a tumor cell multi-drug resistance reversal agent.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to a Radix Radix C21 steroid extract and a preparation method thereof, and also relates to the use of the Radix Radix Radix C21 steroid extract in preparing a tumor cell multidrug resistance reversal agent. Background technique [0002] Malignant tumor is one of the diseases that seriously endanger human health. It is characterized by abnormal cell proliferation and metastasis. Statistics from the World Health Organization show that in 2000, there were about 10 million new cases of malignant tumors in the world, 6.2 million deaths, and 22 million cases of illness; it is estimated that by 2020, there will be 15 million new cases of malignant tumors, 10 million deaths, and 30 million illnesses. Thousands of cases. Chemotherapy is one of the methods of comprehensive therapy for malignant tumors. It is widely used before, during and after surgery. However, the phenomenon of multidrug resistance o...
