Problems solved by technology

[0013] The existing Rhizoma chamaejasma preparations include chamaejasma injection, chamaejasma solution (external use), chamaejasma ointment, etc., the main active ingredient is ethanol extract or water extract, due to the simple extraction process, which contains a large number of mixed ingredients, resulting in side effects of the preparation Large, poor preparation stability, high toxicity and poor curative effect
[0014] Using high-purity extracts, some are difficult to make suitable preparations, some have poor stability, some are difficult to dissolve in water, and have low bioavailability, etc.

Embodiment 1

[0077] Preparation of Daphne chamaejasme Component 1:

[0078] A Daphne chamaejasme extract is characterized in that it is prepared by the following method:

[0079] Step 1. After crushing 1kg of Rhizoma chamaejasma, add 10L of acetone:ethanol=2:1(v:v) mixed solution, heat and reflux for 1 hour, filter out the extract, and add 10L of acetone:ethanol=2:1( v: the mixed solution of v), heated to reflux for 1 hour, filtered out the extract, and combined the filtrate to obtain the extract;

[0080] Step 2, recover the solvent from the combined extract under reduced pressure, concentrate and dry to obtain 85g of dry extract, take 2kg of HPD100 macroporous resin, mix with the dry extract and mix the sample; first, use ethanol:ethyl acetate=1: 1 (v: v) 5 L was used as mobile phase for elution, and then 95% ethanol (v: v) 5 L was used as mobile phase for elution to obtain an eluent. After recovering ethanol from the eluent, it was concentrated and dried to obtain a 15 g sample;

Abstract

The invention relates to a Chinese stellera root component patch. The component is prepared by the following method: extracting Chinese stellera root by using an acetone-alcohol mixed solution; processing the extracting liquid with macroporous resin and then carrying out gradient elution by using preparative chromatography, wherein a mobile phase A is water and the mobile phase B is acetonitrile; collecting eluant within a time period of 45-50 minutes, concentrating and drying to obtain the Chinese stellera root component patch.

Description

Technical field: [0001] The invention relates to an anti-tumor traditional Chinese medicine extract, in particular to an anti-tumor extract extracted from the traditional Chinese medicine Daphne chamaejasme and its extraction method and application. Background technique: [0002] Chinese herbal medicine Stellera chamaejasme, English name: RADIX STELLERAE CHAMAEJASMES, is the dry root of Stellera chamaejasme. Excavated in autumn, removed impurities and dried in the sun, the medicinal materials are spindle-shaped, conical or long cylindrical, slightly curved, single or branched, varying in length, with remnants of aboveground stems at the root, brown to tan surface, and twisted Longitudinal grooves and raised lenticels and lateral root scars, and white soft fibers are exposed at the cork peeling off. Light in body, tough in quality, not easy to break, and the section is fibrous. The cortex is white, and the wood is white. Slight gas, slightly pungent taste, slightly lower t...
